GENERAL DESCRIPTION
The MX29F1610A/B is a 16-mega bit Flash memory organized as either 1M wordx16 or 2M bytex8. The MX29F1610A/B includes 16-128KB(131,072) blocks or 16-64KW(65,536) blocks. MXIC's Flash memories offer the most cost-effective and reliable read/write nonvolatile random access memory. The MX29F1610A/B is packaged in 48-pin TSOP or 44-pin SOP. For 48-pin TSOP, CE2 and RY/BY are extra pins compared with 44pin SOP package. This is to optimize the products (such as solid-state disk drives or flash memory cards) control pin budget. All the above three pins(CE2,RY/BY and PWD) plus one extra VCC pin are not provided in 44-pin SOP. It is designed to be reprogrammed and erased insystem or in-standard EPROM programmers. The standard MX29F1610A/B offers access times as fast as 70ns,allowing operation of high-speed microprocessors without wait. To eliminate bus contention, the MX29F1610A/B has separate chip enables(CE1 and CE2), output enable (OE), and write enable (WE) controls. MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The MX29F1610A/B uses a command register to manage this functionality. The command register allows for 100% TTL level control inputs and fixed power supply levels during erase and programming, while maintaining maximum EPROM compatibility. To allow for simple in-system reprogrammability, the MX29F1610A/B does not require high input voltages for programming. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM. MXIC Flash technology reliably stores memory contents even after 100,000 cycles. The MXIC's cell is designed to optimize the erase and programming mechanisms. In addition, the combination of advanced tunnel oxide processing and low internal electric fields for erase and programming operations produces reliable cycling. The MX29F1610A/B uses a 5V 10% VCC supply to perform the Auto Erase and Auto Program algorithms. The highest degree of latch-up protection is achieved with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on address and data pin from -1V to VCC +1V.

SYMBOL A0 - A19 Q0 - Q7 TYPE INPUT INPUT/OUTPUT NAME AND FUNCTION ADDRESS INPUTS: for memory addresses. Addresses are internally latched during a write cycle. LOW-BYTE DATA BUS: Input data and commands during Command Interface Register(CIR) write cycles. Outputs array,status and identifier data in the appropriate read mode. Floated when the chip is de-selected or the outputs are disabled. HIGH-BYTE DATA BUS: Inputs data during x 16 Data-Write operations. Outputs array, identifier data in the appropriate read mode; not used for status register reads. Floated when the chip is de-selected or the outputs are disabled Selects between high-byte data INPUT/OUTPUT(BYTE = HIGH) and LSB ADDRESS(BYTE = LOW) CHIP ENABLE INPUTS: Activate the device's control logic, Input buffers, decoders and sense amplifiers. With either CE1 or CE2 high, the device is deselected and power consumption reduces to Standby level upon completion of any current program or erase operations. Both CE1,CE2 must be low to select the device. CE2 is not provided in 44-pin SOP package. All timing specifications are the same for both signals. Device selection occurs with the latter falling edge of CE1 or CE2. The first rising edge of CE1 or CE2 disables the device. POWER-DOWN: Puts the device in deep power-down mode. PWD is active low; PWD high gates normal operation. PWD also locks out erase or program operation when active low providing data protection during power transitions. OUTPUT ENABLES: Gates the device's data through the output buffers during a read cycle OE is active low. WRITE ENABLE: Controls writes to the Command Interface Register(CIR). WE is active low. READY/BUSY: Indicates the status of the internal Write State Machine(WSM). When low it indicates that the WSM is performing a erase or program operation. RY/BY high indicate that the WSM is ready for new commands, sector erase is suspended or the device is in deep power-down mode. RY/BY is always active and does not float to tristate off when the chip is deselected or data output are disabled. WRITE PROTECT: All sectors can be protected by writing a non-volatile protectbit for each sector. When WP is low, all prottect-bits status can not be changed, i.e., the user can not execute Sector Protection and Sector Unprotect. The WP input buffer is disabled when PWD transitions low(deep power-down mode). BYTE ENABLE: BYTE Low places device in x8 mode. All data is then input or output on Q0-7 and Q8-14 float. AddressQ15/A-1 selects between the high and low byte. BYTE high places the device in x16 mode, and turns off the Q15/ A-1 input buffer. Address A0, then becomes the lowest order address.

ManufacturerID DeviceID MX29F1610A/B Write NOTES :
1.X can be VIH or VIL for address or control pins except for RY/BY which is either VOL or VOH. 2.RY/BY output is open drain. When the WSM is ready, Erase is suspended or the device is in deep power-down mode, RY/BY will be at VOH if it is tied to VCC through a 1K ~ 100K resistor. When the RY/BY at VOH is independent of OE while a WSM operation is in progress. 3.PWD at GND 0.2V ensures the lowest deep power-down current. 4. A0 and A1 at VIL provide manufacturer ID codes. A0 at VIH and A1 at VIL provide device ID codes. A0 at VIL, A1 at VIH and with appropriate sector addresses provide Sector Protect Code.(Refer to Table 4) 5. Commands for different Erase operations, Data program operations or Sector Protect operations can only be successfully completed through proper command sequence. 6.While the WSM is running. RY/BY in Level-Mode stays at VOL until all operations are complete. RY/BY goes to VOH when the WSM is not busy or in erase suspend mode. 7. RY/BY may be at VOL while the WSM is busy performing various operations. For example, a status register read during a write operation. 8. VID = 11.5V- 12.5V. 9. Q15/A-1 = VIL, Q0 - Q7 =D0-D7 out . Q15/A-1 = VIH, Q0 - Q7 = D8 -D15 out.

WRITE OPERATIONS
Commands are written to the COMMAND INTERFACE REGISTER (CIR) using standard microprocessor write timings. The CIR serves as the interface between the microprocessor and the internal chip operation. The CIR can decipher Read Array, Read Silicon ID, Erase and Program command. In the event of a read command, the CIR simply points the read path at either the array or the silicon ID, depending on the specific read command given. For a program or erase cycle, the CIR informs the write state machine that a program or erase has been requested. During a program cycle, the write state machine will control the program sequences and the CIR will only respond to status reads. During a sector/chip erase cycle, the CIR will respond to status reads and erase suspend. After the write state machine has completed its task, it will allow the CIR to respond to its full command set. The CIR stays at read status register mode until the microprocessor issues another valid command sequence. Device operations are selected by writing commands into the CIR. Table 3 below defines 16 Mbit flash family command.

DEVICE OPERATION SILICON ID READ
The Silicon ID Read mode allows the reading out of a binary code from the device and will identify its manufacturer and type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the device. To activate this mode, the programming equipment must force VID (11.5V~12.5V) on address pin A9. Two identifier bytes may then be sequenced from the device outputs by toggling address A0 from VIL to VIH. All addresses are don't cares except A0 and A1. The manufacturer and device codes may also be read via the command register, for instances when the MX29F1610A/B is erased or programmed in a system without access to high voltage on the A9 pin. The command sequence is illustrated in Table 3. Byte 0 (A0=VIL) represents the manfacturer's code (MXIC=C2H) and byte 1 (A0=VIH) the device identifier code (MX29F1610A=FAH/MX29F1610B=FBH).
The Silicon ID Read mode will be terminated after the following write command cycle.

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 device remains enabled for reads until the CIR contents are altered by a valid command sequence. 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 content occurs during the power transition. Refer to the AC Read Characteristics and Waveforms for the specific timing parameters. The MX29F1610A/B is accessed like an EPROM. When CE and OE are low and WE is high the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever CE or OE is high. This dual line control gives designers flexibility in preventing bus contention. CE stands for the combination of CE1 and CE2 in MX29F1610A 48-pin TSOP package. CE and stands for CE in 44-pin SOP package. Note that the read/reset command is not valid when program or erase is in progress.
BYTE-WIDE LOAD/WORD-WIDE LOAD
Byte(word) loads are used to enter the 128 bytes(64 words) of a page to be programmed or the software codes for data protection. A byte load(word load) is performed by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE. Either byte-wide load or word-wide load is determined(Byte = VIL or VIH is latched) on the falling edge of the WE(or CE) during the 3rd command write cycle.
PROGRAM
Any page to be programmed should have the page in the erased state first, i.e. performing sector erase is suggested before page programming can be performed. The device is programmed on a page basis. If a byte(word) of data within a page is to be changed, data for the entire page can be loaded into the device. Any byte(word) that is not loaded during the programming of its page will be still in the erased state (i.e. FFH). Once the bytes of a page are loaded into the device, they are simultaneously programmed during the internal programming period. After the first data byte(word) has been loaded into the device, successive bytes(words) are entered in the same manner. The time between byte (word) loads must be less than 30us otherwise the load period could be teminated. A6 to A19 specify the page address, i.e., the device is page-aligned on 128 bytes(64 words)boundary. The page address must be valid during each high to low transition of WE or CE. A-1 to A5 specify the byte address within the page, A0 to A5 specify the word address withih the page. The byte(word) may be loaded in any order; sequential loading is not required. If a high to low transition of CE or WE is not detected whithin 100us of the last low to high transition, the load period will end and the internal programming period will start. The Auto page program terminates when status on DQ7 is '1' at which time the device stays at read status register mode until the CIR contents are altered by a valid command sequence.(Refer to table 3,6 and Figure 1,7,8)
PAGE PROGRAM
To initiate Page program mode, a three-cycle command sequence is required. There are two " unlock" write cycles. These are followed by writing the page program command-A0H. Any attempt to write to the device without the three-cycle command sequence will not start the internal Write State Machine(WSM), no data will be written to the device. After three-cycle command sequence is given, a byte(word) load is performed by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE. Maximum of 128 bytes of data may be loaded into each page by the same procedure as outlined in the page program section below.

MX29F1610A/B
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-80H. Two more "unlock" write cycles are then followed by the chip erase command-10H. Chip erase does not require the user to program the device prior to erase. The automatic erase begins on the rising edge of the last WE pulse in the command sequence and terminates when the status on DQ7 is "1" at which time the device stays at read status register mode. The device remains enabled for read status register mode until the CIR contents are altered by a valid command sequence.(Refer to table 3,6 and Figure 2,7,9) Sector erase does not require the user to program the device prior to erase. The system is not required to provide any controls or timings during these operations. The automatic sector erase begins on the rising edge of the last WE pulse in the command sequence and terminates when the status on DQ7 is "1" at which time the device stays at read status register mode. The device remains enabled for read status register mode until the CIR contents are altered by a valid command sequence.(Refer to table 3,6 and Figure 3,4,7,9))
ERASE SUSPEND
This command only has meaning while the the WSM is executing SECTOR erase operation, and therefore will only be responded to during SECTOR erase operation. After this command has been executed, the CIR will initiate the WSM to suspend erase operations, and then return to Read Status Register mode. The WSM will set the DQ6 bit to a "1". Once the WSM has reached the Suspend state,the WSM will set the DQ7 bit to a "1", At this time, WSM allows the CIR to respond to the Read Array, Read Status Register and Erase Resume commands only. In this mode, the CIR will not resopnd to any other comands. The WSM will continue to run, idling in the SUSPEND state, regardless of the state of all input control pins, with the exclusion of PWD. PWD low will immediately shut down the WSM and the remainder of the chip.

This command will cause the CIR to clear the suspend state and set the DQ6 to a '0', but only if an Erase Suspend command was previously issued. Erase Resume will not have any effect in all other conditions.
SECTOR ERASE
Sector erase is a six-bus cycle operation. There are two "unlock" write cycles. These are followed by writing the set-up command-80H. Two more "unlock" write cycles are then followed by the sector erase command-30H. The sector address is latched on the falling edge of WE, while the command (data) is latched on the rising edge of WE.

READ STATUS REGISTER
The MXIC's16 Mbit flash family contains a status register which may be read to determine when a program or erase operation is complete, and whether that operation completed successfully. The status register may be read at any time by writing the Read Status command to the CIR. After writing this command, all subsequent read operations output data from the status register until another valid command sequence is written to the CIR. A Read Array command must be written to the CIR to return to the Read Array mode. The status register bits are output on DQ2 - DQ7(table 6) whether the device is in the byte-wide (x8) or word-wide (x16) mode for the MX29F1610. In the word-wide mode the upper byte, DQ(8:15) is set to 00H during a Read Status command. In the byte-wide mode, DQ(8:14) are tri-stated and DQ15/A-1 retains the low order address function. DQ0-DQ1 is set to 0H in either x8 or x16 mode. It should be noted that the contents of the status register are latched on the falling edge of OE or CE whichever occurs last in the read cycle. This prevents possible bus errors which might occur if the contents of the status register change while reading the status register. CE or OE must be toggled with each subsequent status read, or the completion of a program or erase operation will not be evident. The Status Register is the interface between the microprocessor and the Write State Machine (WSM). When the WSM is active, this register will indicate the status of the WSM, and will also hold the bits indicating whether or not the WSM was successful in performing the desired operation. The WSM sets status bits four through seven and clears bits six and seven, but cannot clear status bits four and five. If Erase fail or Program fail status bit is detected, the Status Register is not cleared until the Clear Status Register command is written. The MX29F1610A/B automatically outputs Status Register data when read after Chip Erase, Sector Erase, Page Program or Read Status Command write cycle. The internal state machine is set for reading array data upon device power-up, or after deep power-down mode.
CLEAR STATUS REGISTER
The Eraes fail status bit (DQ5) and Program fail status bit (DQ4) are set by the write state machine, and can only be reset by the system software. These bits can indicate various failure conditions(see Table 6). By allowing the system software to control the resetting of these bits, several operations may be performed (such as cumulatively programming several pages or erasing multiple blocks in squence). The status register may then be read to determine if an error occurred during that programming or erasure series. This adds flexibility to the way the device may be programmed or erased. Additionally, once the program(erase) fail bit happens, the program (erase) operation can not be performed further. The program(erase) fail bit must be reset by system software before further page program or sector (chip) erase are attempted. To clear the status register, the Clear Status Register command is written to the CIR. Then, any other command may be issued to the CIR. Note again that before a read cycle can be initiated, a Read command must be written to the CIR to specify whether the read data is to come from the Array, Status Register or Silicon ID.

HARDWARE SECTOR PROTECTION
The MX29F1610A/B features sector protection. This feature will disable both program and erase operations. The sector protection feature is enabled using system software by the user(Refer to table 3). The device is shipped with all sectors unprotected. Alternatively, MXIC may protect all sectors in the factory prior to shipping the device.
SECTOR UNPROTECT
It is also possible to unprotect the sector , same as the first five write command cycles in activating sector protection mode followed by the Unprotect Sector command - 40H, the automatic Unprotect operation begins on the rising edge of the last WE pulse in the command sequence and terminates when the Status on DQ7 is '1' at which time the device stays at the read status register mode.(Refer to table 3,6 and Figure 11,12) The users have to write Verify Sector Protect command to verify protect status after executing Sector Unprotect. The device remains enabled for read status register mode until the CIR contents are altered by a valid command sequence. Either Protect or Unprotect sector mode is accomplished by keeping WP high, i.e. protect-bit status can only be changed with a valid command sequence and WP at high. Protect-bit status will not be changed during chip/sector erase operations. Only unprotected sectors can be programmed or erased regardless of the WP pin.
SECTOR PROTECTION
To activate this mode, a six-bus cycle operation is required. 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 Lock Sector command - 20H. Sector address is latched on the falling edge of CE or WE of the sixth cycle of the command sequence. The automatic Lock operation begins on the rising edge of the last WE pulse in the command sequence and terminates when the Status on DQ7 is '1' at which time the device stays at the read status register mode. The users have to write Verify Sector Protect command to verify protect status after executing Sector Protector. The device remains enabled for read status register mode until the CIR contents are altered by a valid command sequence (Refer to table 3,6 and Figure 10,12 ).
DEEP POWER-DOWN MODE
The MXIC's16 Mbit flash family supports a typical ICC of 1uA in deep power-down mode. One of the target markets for these devices is in protable equipment where the power consumption of the machine is of prime importance. When PWD is a logic low (GND 0.2V), all circuits are turned off and the device typically draws 1uA of ICC current. During erase or program modes, PWD low will abort either erase or program operation. The contents of the memory are no longer valid as the data has been corrupted by the PWD function. PWD transitions to VIL or turning power off to the device will clear the status register. PWD pin is not provided in 44-pin SOP package.
VERIFY SECTOR PROTECT
To verify the Protect status, operation is initiated by writing Silicon ID read command into the command register. Following the command write, a read cycle from address XXX0H retrieves the Manufacturer code of C2H. A read cycle from XXX1H returns the Device code FAH/ FBH. A read cycle from appropriate address returns information as to which sectors are protected. To terminate the operation, it is necessary to write the read/ reset command sequence into the CIR. (Refer to table 3,4 and Figure 12)
A few retries are required if Protect status can not be verified successfully after each operation.

RY/BY PIN POLLING AND PROGRAM/ERASE 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 VLKO(= 3.2V , typically 3.5V). 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 user's responsibility to ensure that the control pins are logically correct to prevent unintentional write when VCC is above VLKO.
RY/BY is a dedicated, open-drain page program and sector erase completion. It transitions to VOL after a program or erase command sequence is written to the MX29F1610A/B, and returns to VCC when the WSM has finished executing the internal algorithm. Since RY/BY is an open-drain output, several RY/BY pins can be tied together in parallel with a pull-up resistor to VCC. RY/BY can be connected to the interrupt input of the system CPU or controller. It is active at all times, not tristated if the CE or OE inputs are brought to VIH. RY/ BY is also VCC when the device is in erase suspend or deep power-down modes. RY/BY pin is not provided in 44-pin SOP package.
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 10ns (typical) on CE or WE will not initiate a write cycle.
DATA PROTECTION
The MX29F1610A/B 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 in the Read Array mode. Also, with its control register architecture, alteration of the memory contents only occurs after successful completion of specific multi-bus cycle command sequences. The device also incorporates several features to prevent inadvertent write cycles resulting from VCC power-up and power-down transitions or system noise.
LOGICAL INHIBIT
Writing is inhibited by holding any one of OE = VIL,CE = VIH or WE = VIH. To initiate a write cycle CE and WE must be a logical zero while OE is a logical one.
