s DESCRIPTION
The MBM29F160TE/BE is a 16M-bit, 5.0 V-only Flash memory organized as 2M bytes of 8 bits each or 1M words of 16 bits each. The MBM29F160TE/BE is offered in a 48-pin TSOP (1) package. The device is designed to be programmed in-system with the standard system 5.0 V VCC supply. 12.0 V VPP is not required for write or erase operations. The device can also be reprogrammed in standard EPROM programmers. The standard MBM29F160TE/BE offers access times of 55 ns, 70 ns and 90 ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention the device has separate chip enable (CE), write enable (WE) and output enable (OE) controls. The MBM29F160TE/BE is pin and command set compatible with JEDEC standard E2PROMs. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from 12.0 V Flash or EPROM devices.

(Continued)
The MBM29F160TE/BE is programmed by executing the program command sequence. This will invoke the Embedded ProgramTM* Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margins. Typically, each sector can be programmed and verified in about 0.5 seconds. Erase is accomplished by executing the erase command sequence. This will invoke the Embedded EraseTM* Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margins. Any individual sector is typically erased and verified in 1.0 second. (If already preprogrammed.) The device also features a sector erase architecture. The sector mode allows each sector to be erased and reprogrammed without affecting other sectors. The MBM29F160TE/BE is erased when shipped from the factory. The device features single 5.0 V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7, by the Toggle Bit feature on DQ6, or the RY/BY output pin. Once the end of a program or erase cycle has been completed, the device internally resets to the read mode. The MBM29F160TE/BE also has a hardware RESET pin. When this pin is driven low, execution of any Embedded Program Algorithm or Embedded Erase Algorithm is terminated. The internal state machine is then reset to the read mode. The RESET pin may be tied to the system reset circuitry. Therefore, if a system reset occurs during the Embedded Program Algorithm or Embedded Erase Algorithm, the device is automatically reset to the read mode and will have erroneous data stored in the address locations being programmed or erased. These locations need re-writing after the Reset. Resetting the device enables the system's microprocessor to read the boot-up firmware from the Flash memory. Fujitsu's Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The MBM29F160TE/BE memory electrically erases all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The bytes/words are programmed one byte/word at a time using the EPROM programming mechanism of hot electron injection. *: Embedded EraseTM and Embedded ProgramTM are trademarks of Advanced Micro Devices, Inc.

MBM29F160TE70/90/MBM29F160BE70/90
s FUNCTIONAL DESCRIPTION
1. Read Mode
The MBM29F160TE/BE has two control functions which must be satisfied in order to obtain data at the outputs. CE is the power control and should be used for a device selection. OE is the output control and should be used to gate data to the output pins if a device is selected. Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable access time (tCE) is the delay from stable addresses and stable CE to valid data at the output pins. The output enable access time is the delay from the falling edge of OE to valid data at the output pins. (Assuming the addresses have been stable for at least tACC - tOE time.) When reading out a data without changing addresses after power-u, it is necessary to input hardware reset or change CE pin from "H" to "L".
2. Standby Mode
There are two ways to implement the standby mode on the MBM29F160TE/BE devices. One is by using both the CE and RESET pins; the other via the RESET pin only. When using both pins, a CMOS standby mode is achieved with CE and RESET inputs both held at VCC 0.3 V. Under this condition the current consumed is less than 5 A Max. During Embedded Algorithm operation, VCC Active current (ICC2) is required even CE = "H". The device can be read with standard access time (tCE) from either of these standby modes. When using the RESET pin only, a CMOS standby mode is achieved with the RESET input held at VSS 0.3 V (CE = "H" or "L"). Under this condition the current consumed is less than 5 A Max. Once the RESET pin is taken high, the device requires tRH of wake up time before outputs are valid for read access. In the standby mode, the outputs are in the high-impedance state, independent of the OE input.
3. Output Disable
If the OE input is at a logic high level (VIH), output from the device is disabled. This will cause the output pins to be in a high-impedance state.
4. Autoselect
The Autoselect mode allows the reading out of a binary code from the device and will identify its manufacturer and type. The intent is to allow programming equipment to automatically match the device to be programmed with its corresponding programming algorithm. The Autoselect command may also be used to check the status of write-protected sectors. (See "MBM29F160TE/BE Sector Protection Verify Autoselect Code Table" and "Expanded Autoselect Code Table" in sDEVICE BUS OPERATIONS.) This mode is functional over the entire temperature range of the device. To activate this mode, the programming equipment must force VID (11.5 V to 12.5 V) on address pin A9. Two identifier bytes may then be sequenced from the devices outputs by toggling address A0 from VIL to VIH. All addresses are DON'T CARES except A0, A1 and A6 (A-1). (See "MBM29F160TE/BE User Bus Operation Tables (BYTE = VIH and BYTE = VIL)" in sDEVICE BUS OPERATIONS.) The manufacturer and device codes may also be read via the command register, for instances when the MBM29F160TE/BE is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in "MBM29F160TE/BE Standard Command Definitions Table" in sDEVICE BUS OPERATIONS. Byte 0 (A0 = VIL) represents the manufacture's code (Fujitsu = 04h) and byte 1 (A0 = VIH) represents the device identifier code (MBM29F160TE = D2h and MBM29F160BE = D8h for x 8 mode; MBM29F160TE = 22D2h and MBM29F160BE = 22D8h for x 16 mode). These two bytes/words are given in "MBM29F160TE/BE Sector Protection Verify Autoselect Code Table" and "Extended Autoselect Code Table" (sDEVICE BUS OPERATIONS). All identifiers for manufactures and device will exhibit odd parity with DQ7 defined as the parity bit. In order to read the proper device codes when executing the Autoselect, A1 must be VIL. (See "MBM29F160TE/BE Sector Protection Verify Autoselect Code Table" and "Extended Autoselect Code Table" in sDEVICE BUS OPERATIONS.)

5. Write
Device erasure and programming are accomplished via the command register. The command register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. The command register itself does not occupy any addressable memory location. The register is latch used to store the commands, along with the address and data information needed to execute the command. The command register is written by bringing WE to VIL, while CE is at VIL and OE is at VIH. Addresses are latched on the falling edge of CE or WE, whichever occurs later, while data is latched on the rising edge of CE or WE pulse, whichever occurs first. Standard microprocessor write timings are used. Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.
6. Write Protect (WP)
The write Protect function provides a hardware method of protecting certain boot sectors without using VID. If the system asserts VIL on the WP pin, the device disables program and erase functions in the "outermost" 16K byte boot sectors independently of whether this sector was protected or unprotected using the method described in "Sector / Sector Block Protection and Unprotection". The outmost 16K byte boot sector is the sector containing the lowest addresses in a bottom-boot-configured devices, or the sector containing the highest addresses in a top-boot-configured device. If the system asserts VIH on the WP pin, the devices reverts to whether the outmost 16K byte boot sector was last set to be protected or unprotected. That is, sector protection or unprotection for this sector depends on whether it was last protected or unprotected using the method describe in "Sector / Sector Block Protection and Unprotection".
7. Sector Protection
The MBM29F160TE/BE features hardware sector protection. This feature will disable both program and erase operations in any number of sectors (0 through 34). The sector protection feature is enabled using programming equipment at the user's site. The device is shipped with all sectors unprotected. To activate this mode, the programming equipment must force VID on address pin A9 and control pin OE, (suggest VID = 11.5 V), CE = VIL and A6 = VIL. The sector addresses (A19, A18, A17, A16, A15, A14, A13 and A12) should be set to the sector to be protected. "Sector Address Tables (MBM29F160TE/BE)" in sFLEXIBLE SECTOR-ERASE ARCHITECTURE define the sector address for each of the thirty five (35) individual sectors. Programming of the protection circuitry begins on the falling edge of the WE pulse and is terminated with the rising edge of the same. Sector addresses must be held constant during the WE pulse. See "13. AC Waveforms for Sector Protection Timing Diagram" in sTIMING DIAGRAM and "6. Temporary Sector Unprotection Algorithm" in sFLOW CHART for sector protection waveforms and algorithm. To verify programming of the protection circuitry, the programming equipment must force VID on address pin A9 with CE and OE at VIL and WE at VIH. Scanning the sector addresses (A19, A18, A17, A16, A15, A14, A13 and A12) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" code at device output DQ0 for a protected sector. Otherwise the devices will read 00h for unprotected sector. In this mode, the lower order addresses, except for A0, A1 and A6 are DON'T CARES. Address locations with A1 = VIL are reserved for Autoselect manufacturer and device codes. A-1 requires to apply to VIL in byte mode. It is also possible to determine if a sector is protected in the system by writing an Autoselect command. Performing a read operation at the address location XX02h, where the higher order addresses pins (A19, A18, A17, A16, A15, A14, A13 and A12) represents the sector address will produce a logical "1" at DQ0 for a protected sector. See "MBM29F160TE/BE Sector Protection Verify Autoselect Code Table" and "Extended Autoselect Code Table" in sDEVICE BUS OPERATIONS for Autoselect codes.
8. Temporary Sector Unprotection
This feature allows temporary unprotection of previously protected sectors of the MBM29F160TE/BE devices in order to change data. The Sector Unprotection mode is activated by setting the RESET pin to high voltage (12 V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once the 12 V is taken away from the RESET pin, all the previously protected sectors will be protected again. Refer to "14. Temporary Sector Unprotection Timing Diagram" in sTIMING DIAGRAM and "6. Temporary Sector Unprotection Algorithm" in sFLOW CHART. 16

s COMMAND DEFINITIONS
Device operations are selected by writing specific address and data sequences into the command register. Writing incorrect address and data values or writing them in an improper sequence will reset the device to the read mode. "MBM29F160TE/BE Standard Command Definitions Table" in sDEVICE BUS OPERATIONS defines the valid register command sequences. Note that the Erase Suspend (B0h) and Erase Resume (30h) commands are valid only while the Sector Erase operation is in progress. Moreover both Read/Reset commands are functionally equivalent, resetting the device to the read mode. Please note that commands are always written at DQ7 to DQ0 and DQ15 to DQ8 bits are ignored.
1. Read/Reset Command
The read or reset operation is initiated by writing the Read/Reset command sequence into the command register. Microprocessor read cycles retrieve array data from the memory. The devices remain enabled for reads until the command register contents are altered. The device will automatically power-up in the Read/Reset state. In this case, a command sequence is not required to read data. Standard microprocessor read cycles will retrieve array data. This default value ensures that no spurious alteration of the memory contents occurs during the power transition. Refer to the AC Read Characteristics and Waveforms for specific timing parameters.
2. Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such, manufactures and device codes must be accessible while the device resides in the target system. PROM programmers typically access the signature codes by raising A9 to a high voltage. However, multiplexing high voltage onto the address lines is not generally desired system design practice. The device contains an Autoselect command operation to supplement traditional PROM programming methodology. The operation is initiated by writing the Autoselect command sequence into the command register. Following the last command write, a read cycle from address XX00h retrieves the manufacture code of 04h. A read cycle from address XX01h for x16 (XX02h for x8) retrieves the device code (MBM29F160TE = D2h and MBM29F160BE = D8h for x8 mode; MBM29F160TE = 22D2h and MBM29F160BE = 22D8h for x16 mode). (See "MBM29F160TE/BE Sector Protection Verify Autoselect Code Table" and "Extended Autoselect Code Table" in sDEVICE BUS OPERATIONS.) All manufactures and device codes will exhibit odd parity with DQ7 defined as the parity bit. The sector state (protection or unprotection) will be indicated by address XX02h for x16 (XX04h for x8). Scanning the sector addresses (A19, A18, A17, A16, A15, A14, A13 and A12) while (A6, A1, A0) = (0, 1, 0) will produce a logical "1" at device output DQ0 for a protected sector. The programming verification should be perform margin mode verification on the protected sector. (See "MBM29F160TE/BE User Bus Operation Tables (BYTE = VIH and BYTE = VIL)" in sDEVICE BUS OPERATIONS.) To terminate the operation, it is necessary to write the Read/Reset command sequence into the register and, also to write the Autoselect command during the operation, by executing it after writing the Read/Reset command sequence.
3. Byte/Word Programming
The device is programmed on a byte-by-byte (or word-by-word) basis. Programming is a four bus cycle operation. There are two "unlock" write cycles. These are followed by the program set-up command and data write cycles. Addresses are latched on the falling edge of CE or WE, whichever happens later and the data is latched on the rising edge of CE or WE, whichever happens first. The rising edge of the last CE or WE (whichever happens first) begins programming. Upon executing the Embedded Program Algorithm command sequence, the system is not required to provide further controls or timings. The device will automatically provide adequate internally generated program pulses and verify the programmed cell margin. (See "3. AC Waveforms for Alternate WE Controlled Program Operations" and "4. AC Waveforms for Alternate CE Controlled Program Operations" in sTIMING DIAGRAM.) The automatic programming operation is completed when the data on DQ7 is equivalent to data written to this bit at which time the device return to the read mode and addresses are no longer latched. (See "Hardware 17
MBM29F160TE70/90/MBM29F160BE70/90
Sequence Flags Table".) Therefore, the device requires that a valid address to the devices be supplied by the system at this particular instance of time. Hence, Data Polling must be performed at the memory location which is being programmed. Any commands written to the chip during this period will be ignored. If hardware reset occurs during the programming operation, it is impossible to guarantee the data are being written. Programming is allowed in any sequence and across sector boundaries. Beware that a data "0" cannot be programmed back to a "1". Attempting to do so may either hang up the device or result in an apparent success according to the data polling algorithm but a read from read/reset mode will show that the data is still "0". Only erase operations can convert "0"s to "1"s. "1. Embedded ProgramTM Algorithm" in sFLOW CHART illustrates the Embedded ProgramTM Algorithm using typical command strings and bus operations.
4. Chip Erase
Chip erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the chip erase command. Chip erase does not require the user to program the device prior to erase. Upon executing the Embedded EraseTM Algorithm command sequence the device will automatically program and verify the entire memory for an all zero data pattern prior to electrical erase. (Preprogram Function.) The system is not required to provide any controls or timings during these operations. The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates when the data on DQ7 is "1" (See "8. Write Operation Status".) at which time the device returns to read mode. (See "5. AC Waveforms for Chip/Sector Erase Operations" in sTIMING DIAGRAM.) "2. Embedded EraseTM Algorithm" in sFLOW CHART illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
5. Sector Erase
Sector erase is a six-bus cycle operation. There are two "unlock" write cycles, followed by writing the "set-up" command. Two more "unlock" write cycles are then followed by the Sector Erase command. The sector address (any address location within the desired sector) is latched on the falling edge of WE, while the command (Data = 30h) is latched on the rising edge of WE. After a time-out of 50 s from the rising edge of the last sector erase command, the sector erase operation will begin. Multiple sectors may be erased concurrently by writing six-bus cycle operations on "MBM29F160TE/BE Standard Command Definitions Table" in sDEVICE BUS OPERATIONS. This sequence is followed with writes of the Sector Erase command to addresses in other sectors desired to be concurrently erased. The time between writes must be less than 50 s otherwise that command will not be accepted and erasure will start. It is recommended that processor interrupts be disabled during this time to guarantee this condition. The interrupts can be re-enabled after the last Sector Erase command is written. A time-out of 50 s from the rising edge of the last WE will initiate the execution of the Sector Erase command(s). If another falling edge of the WE occurs within the 50 s time-out window the timer is reset. Monitor DQ3 to determine if the sector erase timer window is still open. (See "12. DQ3", Sector Erase Timer.) Any command other than Sector Erase or Erase Suspend during this time-out period will reset the device to the read mode, ignoring the previous command string. Resetting the device once execution has begun will corrupt the data in the sector. In that case, restart the erase on those sectors and allow them to complete. (Refer to "8. Write Operation Status" for Sector Erase Timer operation.) Loading the sector erase buffer may be done in any sequence and with any number of sectors (0 to 34). Sector erase does not require the user to program the device prior to erase. The device automatically programs all memory locations in the sector(s) to be erased prior to electrical erase. When erasing a sector or sectors the remaining unselected sectors are not affected. The system is not required to provide any controls or timings during these operations. (See "5. AC Waveforms for Chip/Sector Erase Operations" in sTIMING DIAGRAM.) The automatic sector erase begins after the 50 s time out from the rising edge of the WE pulse for the last sector erase command pulse and terminates when the data on DQ7 is "1" (See "8. Write Operation Status".) at which time the device returns to the read mode. Data polling must be performed at an address within any of the sectors being erased. Multiple Sector Erase Time; [Sector Program Time (Preprogramming) + Sector Erase Time] x Number of Sector Erase.

"2. Embedded EraseTM Algorithm" in sFLOW CHART illustrates the Embedded EraseTM Algorithm using typical command strings and bus operations.
6. Erase Suspend/Resume
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform data reads from or program to a sector not being erased. This command is applicable ONLY during the Sector Erase operation which includes the time-out period for sector erase. The Erase Suspend command will be ignored if written during the Chip Erase operation or Embedded Program Algorithm. Writing the Erase Suspend command during the Sector Erase time-out results in immediate termination of the time-out period and suspension of the erase operation. Writing the Erase Resume command resumes the erase operation. The addresses are "DON'T CARES" when writing the Erase Suspend or Erase Resume commands. When the Erase Suspend command is written during the Sector Erase operation, the device will take a maximum of 20 s to suspend the erase operation. When the devices have entered the erase-suspended mode, the RY/ BY output pin and the DQ7 bit will be at logic "1", and DQ6 will stop toggling. The user must use the address of the erasing sector for reading DQ6 and DQ7 to determine if the erase operation has been suspended. Further writes of the Erase Suspend command are ignored. When the erase operation has been suspended, the device defaults to the erase-suspend-read mode. Reading data in this mode is the same as reading from the standard read mode except that the data must be read from sectors that have not been erase-suspended. Successively reading from the erase-suspended sector while the device is in the erase-suspend-read mode will cause DQ2 to toggle. (See "13. DQ2".) After entering the erase-suspend-read mode, the user can program the device by writing the appropriate command sequence for Program. This Program mode is known as the erase-suspend-program mode. Again, programming in this mode is the same as programming in the regular Program mode except that the data must be programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector while the devices are in the erase-suspend-program mode will cause DQ2 to toggle. The end of the erasesuspended Program operation is detected by the RY/BY output pin, Data polling of DQ7, or the Toggle Bit (DQ6) which is the same as the regular Program operation. Note that DQ7 must be read from the Program address while DQ6 can be read from any address. To resume the operation of Sector Erase, the Resume command (30h) should be written. Any further writes of the Resume command at this point will be ignored. Another Erase Suspend command can be written after the chip has resumed erasing.
7. Extended Command
(1) Fast Mode MBM29F160TE/BE has Fast Mode function. This mode dispenses with the initial two unlock cycles required in the standard program command sequence writing Fast Mode command into the command register. In this mode, the required bus cycle for programming is two cycles instead of four bus cycles in standard program command. (Do not write erase command in this mode.) The read operation is also executed after exiting this mode. To exit this mode, it is necessary to write Fast Mode Reset command into the command register. (Refer to "7. Embedded Programming Algorithm for Fast Mode" in sFLOW CHART Extended algorithm.) The VCC active current is required even CE = VIH during Fast Mode. (2) Fast Programming During Fast Mode, the programming can be executed with two bus cycles operation. The Embedded Program Algorithm is executed by writing program set-up command (A0h) and data write cycles (PA/PD). (Refer to "7. Embedded Programming Algorithm for Fast Mode" in sFLOW CHART Extended algorithm.) (3) CFI (Common Flash Memory Interface) The CFI (Common Flash Memory Interface) specification outlines device and host system software interrogation handshake which allows specific vendor-specified software algorithms to be used for entire families of devices. This allows device-independent, JEDEC ID-independent and forward-and backward-compatible software support for the specified flash device families. Refer to CFI specification in detail. The operation is initiated by writing the query command (98h) into the command register. Following the command 19
MBM29F160TE70/90/MBM29F160BE70/90
write, a read cycle from specific address retrieves device information. Please note that output data of upper byte (DQ15 to DQ8) is "0" in word mode (16 bit) read. Refer to "Common Flash Memory Interface Code Table" in sFLEXIBLE SECTOR-ERASE ARCHITECTURE. To terminate operation, it is necessary to write the read/reset command sequence into the register.

However, successive reads from the erase-suspended sector will cause DQ2 to toggle. Notes: * DQ1 and DQ0 are reserve pins for future use. * DQ4 is Fujitsu internal use only.
9. DQ7
Data Polling The MBM29F160TE/BE device features Data Polling as a method to indicate to the host that the Embedded Algorithms are in progress or completed. During the Embedded Program Algorithm, an attempt to read the devices will produce the complement of the data last written to DQ7. Upon completion of the Embedded Program Algorithm, an attempt to read the device will produce the true data last written to DQ7. During the Embedded Erase Algorithm, an attempt to read the device will produce a "0" at the DQ7 output. Upon completion of the Embedded Erase Algorithm an attempt to read the device will produce a "1" at the DQ7 output. The flowchart for Data Polling (DQ7) is shown in "3. Data Polling Algorithm" in sFLOW CHART. For chip erase and sector erase, Data Polling is valid after the rising edge of the sixth WE pulse in the six-write pulse sequence. Data Polling must be performed at a sector address within any of the sectors being erased and not at a protected sector. Otherwise, the status may not be valid. Once the Embedded Algorithm operation is close to being completed, the MBM29F160TE/BE data pins (DQ7) may change asynchronously while the output enable (OE) is asserted low. This means that the device is driving status information on DQ7 at one instant of time and then that byte's valid data at the next instant of time. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device has completed the Embedded Program Algorithm operation and DQ7 has a valid data, the data outputs on DQ6 to DQ0 may be still invalid. The valid data on DQ7 to DQ0 will be read on successive read attempts. The Data Polling feature is only active during the Embedded Programming Algorithm, Embedded Erase Algorithm or sector erase time-out. See "6. AC Waveforms for Data Polling during Embedded Algorithm Operations" in sTIMING DIAGRAM for the Data Polling timing specifications and diagrams. 20
MBM29F160TE70/90/MBM29F160BE70/90
10. DQ6
Toggle Bit I The MBM29F160TE/BE also feature the "Toggle Bit I" as a method to indicate to the host system that the Embedded Algorithms are in progress or completed. During an Embedded Program or Erase Algorithm cycle, successive attempts to read (OE toggling) data from the device will result in DQ6 toggling between one and zero. Once the Embedded Program or Erase Algorithm cycle is completed, DQ6 will stop toggling and valid data can be read on the next successive attempts. During programming, the Toggle Bit I is valid after the rising edge of the fourth WE pulse in the four write pulse sequence. For chip erase and sector erase, the Toggle Bit I is valid after the rising edge of the sixth WE pulse in the sixwrite pulse sequence. The Toggle Bit I is active during the sector time out. In programming, if the sector being written to is protected, the toggle bit will toggle for about 2 s and then stop toggling without the data having changed. In erase, the device will erase all the selected sectors except for the ones that are protected. If all selected sectors are protected, the chip will toggle the Toggle Bit I for about 100 s and then drop back into read mode, having changed none of the data. Either CE or OE toggling will cause the DQ6 to toggle. In addition, an Erase Suspend/Resume command will cause the DQ6 to toggle. See "7. AC Waveforms for Toggle Bit I during Embedded Algorithm Operations" in sTIMING DIAGRAM and "4. Toggle Bit Algorithm" in sFLOW CHART for the Toggle Bit I timing specifications and diagrams.
11. DQ5
Exceeded Timing Limits DQ5 will indicate if the program or erase time has exceeded the specified limits (internal pulse count). Under these conditions DQ5 will produce a "1". This is a failure condition which indicates that the program or erase cycle was not successfully completed. Data Polling is the only operating function of the device under this condition. The CE circuit will partially power down the device under these conditions (to approximately 2 mA). The OE and WE pins will control the output disable functions as described in "MBM29F160TE/BE User Bus Operation Tables (BYTE = VIH and BYTE = VIL)" in sDEVICE BUS OPERATIONS. The DQ5 failure condition may also appear if a user tries to program a non blank location without erasing. In this case the device locks out and never completes the Embedded Algorithm operation. Hence, the system never reads a valid data on DQ7 and DQ6 never stops toggling. Once the device has exceeded timing limits, the DQ5 bit will indicate a "1." Please note that this is not a device failure condition since the device was incorrectly used. If this occurs, reset the device with command sequence.
12. DQ3
Sector Erase Timer After the completion of the initial sector erase command sequence the sector erase time-out will begin. DQ3 will remain low until the time-out is complete. Data Polling and Toggle Bit I are valid after the initial sector erase command sequence. If Data Polling or the Toggle Bit I indicates the device has been written with a valid erase command, DQ3 may be used to determine if the sector erase timer window is still open. If DQ3 is high ("1") the internally controlled erase cycle has begun; attempts to write subsequent commands to the device will be ignored until the erase operation is completed as indicated by Data Polling or Toggle Bit I. If DQ3 is low ("0"), the device will accept additional sector erase commands. To insure the command has been accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the command may not have been accepted. See "Hardware Sequence Flags Table".
13. DQ2
Toggle Bit II This Toggle Bit II, along with DQ6, can be used to determine whether the device is in the Embedded Erase Algorithm or in Erase Suspend. Successive reads from the erasing sector will cause DQ2 to toggle during the Embedded Erase Algorithm. If the 21
MBM29F160TE70/90/MBM29F160BE70/90
device is in the erase-suspended-read mode, successive reads from the erase-suspended sector will cause DQ2 to toggle. When the device is in the erase-suspended-program mode, successive reads from the byte address of the non-erase suspended sector will indicate a logic "1" at DQ2. DQ6 is different from DQ2 in that DQ6 toggles only when the standard program or Erase, or Erase Suspend Program operation is in progress. Toggle Bit Status Table Mode Program Erase Erase Suspend Read (Erase Suspended Sector) Erase-Suspend Program DQ7 DQ7 0 1 DQ7 DQ6 Toggle Toggle 1 Toggle *1 DQ2 1 Toggle Toggle 1 *2
*1: Performing successive read operations from any address will cause DQ6 to toggle. *2: Reading the byte address being programmed while in the erase-suspend program mode will indicate logic "1" at the DQ2 bit. However, successive reads from the erase-suspended sector will cause DQ2 to toggle. For example, DQ2 and DQ6 can be used together to determine if the erase-suspend-read mode is in progress. (DQ2 toggles while DQ6 does not.) See also "Toggle Bit Status Table" and "15. DQ2 vs. DQ6" in sTIMING DIAGRAM. Furthermore, DQ2 can also be used to determine which sector is being erased. When the device is in the erase mode, DQ2 toggles if this bit is read from an erasing sector.
14. RY/BY
Ready/Busy Pin The MBM29F160TE/BE provides a RY/BY open-drain output pin as a way to indicate to the host system that the Embedded Algorithms are either in progress or has been completed. If the output is low, the device is busy with either a program or erase operation. If the output is high, the device is ready to accept any read/write or erase operation. When the RY/BY pin is low, the devices will not accept any additional program or erase commands. If the MBM29F160TE/BE is placed in an Erase Suspend mode, the RY/BY output will be high. During programming, the RY/BY pin is driven low after the rising edge of the fourth WE pulse. During an erase operation, the RY/BY pin is driven low after the rising edge of the sixth WE pulse. The RY/BY pin will indicate a busy condition during the RESET pulse. See "8. RY/BY Timing Diagram during Program/Erase Operations" in sTIMING DIAGRAM and 12 for a detailed timing diagram. Since this is an open-drain output, the pull-up resistor needs to be connected to VCC ; multiples of devices may be connected to the host system via more than one RY/BY pin in parallel.
15. RESET
Hardware Reset Pin The MBM29F160TE/BE device may be reset by driving the RESET pin to VIL. The RESET pin has a pulse requirement and has to be kept low (VIL) for at least tRP in order to properly reset the internal state machine. Any operation in the process of being executed will be terminated and the internal state machine will be reset to the read mode tREADY after the RESET pin is driven low. Furthermore, once the RESET pin goes high, the device requires an additional tRH before it allows read access. When the RESET pin is low, the device will be in the standby mode for the duration of the pulse and all the data output pins will be tri-stated. If a hardware reset occurs during a program or erase operation, the data at that particular location will be corrupted. Please note that the RY/BY output signal should be ignored during the RESET pulse. Refer to "9. RESET, RY/BY Timing Diagram" in sTIMING DIAGRAM for the timing diagram. Refer to "8. Temporary Sector Unprotection" in sFUNCTIONAL DESCRIPTION for additional functionality. 22
MBM29F160TE70/90/MBM29F160BE70/90
If hardware reset occurs during Embedded Erase Algorithm, there is a possibility that the erasing sector(s) will need to be erased again before they can be programmed.
16. Byte/Word Configuration
The BYTE pin selects the byte (8-bit) mode or word (16-bit) mode for the MBM29F160TE/BE device. When this pin is driven high, the device operates in the word (16-bit) mode. The data is read and programmed at DQ15 to DQ0. When this pin is driven low, the device operates in byte (8-bit) mode. Under this mode, DQ15/A-1 pin becomes the lowest address bit and DQ14 to DQ8 bits are tri-stated. However, the command bus cycle is always an 8-bit operation and hence commands are written at DQ7 to DQ0 and DQ15 to DQ8 bits are ignored. Refer to "10. Timing Diagram for Word Mode Configuration" and "11. Timing Diagram for Byte Mode Configuration" in sTIMING DIAGRAM for the timing diagrams.
17. Data Protection
The MBM29F160TE/BE is designed to offer protection against accidental erasure or programming caused by spurious system level signals that may exist during power transitions. During power up the device automatically resets the internal state machine to the Read mode. Also, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific multi-bus cycle command sequence. The device also incorporates several features to prevent inadvertent write cycles resulting form VCC power-up and power-down transitions or system noise.
18. Low VCC Write Inhibit
To avoid initiation of a write cycle during VCC power-up and power-down, a write cycle is locked out for VCC less than 3.2 V (typically 3.7 V). If VCC < VLKO, the command register is disabled and all internal program/erase circuits are disabled. Under this condition, the device will reset to the read mode. Subsequent writes will be ignored until the VCC level is greater than VLKO. It is the users responsibility to ensure that the control pins are logically correct to prevent unintentional writes when VCC is above 3.2 V. If the Embedded Erase Algorithm is interrupted, there is possibility that the erasing sector(s) will need to be erased again prior to programming.
19. Write Pulse "Glitch" Protection
Noise pulses of less than 5 ns (typical) on OE, CE, or WE will not change the command registers.
20. Logical Inhibit
Writing is inhibited by holding any one of OE = VIL, CE = VIH, or WE = VIH. To initiate a write, CE and WE must be a logical zero while OE is a logical one.
21. Power-up Write Inhibit
Power-up of the devices with WE = CE = VIL and OE = VIH will not accept commands on the rising edge of WE. The internal state machine is automatically reset to read mode on power-up.
22. Sector Protection
Device user is able to protect each sector individually to store and protect data. Protection circuit voids both write and erase commands that are addressed to protected sectors. Any commands to write or erase addressed to protected sector are ignore. Refer to "7. Sector Protection" in s FUNCTIONAL DESCRIPTION.
