32-megabit (2M x 16) 3-volt Only Flash Memory AT49BV320D AT49BV320DT
1. Description
The AT49BV320D(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152 words of 16 bits each. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP package and a 47-ball CBGA package. The device has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it ideally suited for in-system programming. The device powers on in the read mode. Command sequences are used to place the device in other operation modes such as program and erase. The device has the capability to protect the data in any sector (see "Flexible Sector Protection" on page 6). To increase the flexibility of the device, it contains an Erase Suspend and Program Suspend feature. This feature will put the erase or program on hold for any amount of time and let the user read data from or program data to any of the remaining sectors within the memory. The VPP pin provides data protection. When the VPP input is below 0.4V, the program and erase functions are inhibited. When VPP is at 1.65V or above, normal program and erase operations can be performed. With VPP at 10.0V, the program (Dual-word Program command) operation is accelerated.

4. Device Operation
4.1 Command Sequences
When the device is first powered on, it will be in the read mode. In order to perform other device functions, a series of command sequences are entered into the device. The command sequences are shown in the "Command Definition Table" on page 15 (I/O8 - I/O15 are don't care inputs for the command codes). The command sequences are written by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address and data are latched by the first rising edge of CE or WE. Standard microprocessor write timings are used. The address locations used in the command sequences are not affected by entering the command sequences.
4.2
Read
When the AT49BV320D(T) is in the read mode, with CE and OE low and WE high, the data stored at the memory location determined by the address pins are asserted on the outputs. The
3
3581C-FLASH-11/05
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.
4.3
Reset
A RESET input pin is provided to ease some system applications. When RESET is at a logic high level, the device is in its standard operating mode. A low level on the RESET input halts the present device operation and puts the outputs of the device in a high impedance state. When a high level is reasserted on the RESET pin, the device returns to the read mode, depending upon the state of the control inputs.
4.4
Erase
Before a word can be reprogrammed, it must be erased. The erased state of memory bits is a logical "1". The individual sectors can be erased by using the Sector Erase command.
4.4.1
Sector Erase The device is organized into 71 sectors (SA0 - SA70) that can be individually erased. The Sector Erase command is a two-bus cycle operation. The sector address and the D0H Data Input command are latched on the rising edge of WE. The sector erase starts after the rising edge of WE of the second cycle provided the given sector has not been protected. The erase operation is internally controlled; it will automatically time to completion. The maximum time to erase a sector is tSEC. An attempt to erase a sector that has been protected will result in the operation terminating immediately.
4.5
Word Programming
Once a memory sector is erased, it is programmed (to a logical "0") on a word-by-word basis. Programming is accomplished via the Internal Device command register and is a two-bus cycle operation. The device will automatically generate the required internal program pulses. Any commands, except Read Status Register, Program Suspend and Program Resume, written to the chip during the embedded programming cycle will be ignored. If a hardware reset happens during programming, the data at the location being programmed will be corrupted. Please note that a data "0" cannot be programmed back to a "1"; only erase operations can convert "0"s to "1"s. Programming is completed after the specified tBP cycle time. If the program status bit is a "1", the device was not able to verify that the program operation was performed successfully. The status register indicates the programming status. While the program sequence executes, status bit I/O7 is "0".
4.6
VPP Pin
The circuitry of the AT49BV320D(T) is designed so that the device cannot be programmed or erased if the VPP voltage is less that 0.4V. When VPP is at 1.65V or above, normal program and erase operations can be performed. The VPP pin cannot be left floating.

4.7 Read Status Register
The status register indicates the status of device operations and the success/failure of that operation. The Read Status Register command causes subsequent reads to output data from the status register until another command is issued. To return to reading from the memory, issue a Read command. The status register bits are output on I/O7 - I/O0. The upper byte, I/O15 - I/O8, outputs 00H when a Read Status Register command is issued. The contents of the status register [SR7:SR0] are latched on the falling edge of OE or CE (whichever occurs last), which prevents possible bus errors that might occur if status register contents change while being read. CE or OE must be toggled with each subsequent status read, or the status register will not indicate completion of a Program or Erase operation. When the Write State Machine (WSM) is active, SR7 will indicate the status of the WSM; the remaining bits in the status register indicate whether the WSM was successful in performing the preferred operation (see Table 4-1). Table 4-1.

ESS 6 ES 5 PS 4 VPPS 3 PSS 2 Notes SLS 1 R 0

Check Write State Machine bit first to determine Word Program or Sector Erase completion, before checking program or erase status bits. When Erase Suspend is issued, WSM halts execution and sets both WSMS and ESS bits to "1" - ESS bit remains set to "1" until an Erase Resume command is issued. When this bit is set to "1", WSM has applied the max number of erase pulses to the sector and is still unable to verify successful sector erasure. When this bit is set to "1", WSM has attempted but failed to program a word The VPP status bit does not provide continuous indication of VPP level. The WSM interrogates VPP level only after the Program or Erase command sequences have been entered and informs the system if VPP has not been switched on. The VPP is also checked before the operation is verified by the WSM. When Program Suspend is issued, WSM halts execution and sets both WSMS and PSS bits to "1". PSS bit remains set to "1" until a Program Resume command is issued. If a Program or Erase operation is attempted to one of the locked sectors, this bit is set by the WSM. The operation specified is aborted and the device is returned to read status mode. This bit is reserved for future use and should be masked out when polling the status register.
1. A Command Sequence Error is indicated when SR1, SR3, SR4 and SR5 are set.

3581C-FLASH-11/05
4.7.1
Clear Status Register The WSM can set status register bits 1 through 7 and can clear bits 2, 6 and 7; but, the WSM cannot clear status register bits 1, 3, 4 or 5. Because bits 1, 3, 4 and 5 indicate various error conditions, these bits can be cleared only through the Clear Status Register command. By allowing the system software to control the resetting of these bits, several operations may be performed (such as cumulatively programming several addresses or erasing multiple sectors in sequence) before reading the status register to determine if an error occurred during those operations. The status register should be cleared before beginning another operation. The Read command must be issued before data can be read from the memory array. The status register can also be cleared by resetting the device.
4.8
Flexible Sector Protection
The AT49BV320D(T) offers two sector protection modes, the Softlock and the Hardlock. The Softlock mode is optimized as sector protection for sectors whose content changes frequently. The Hardlock protection mode is recommended for sectors whose content changes infrequently. Once either of these two modes is enabled, the contents of the selected sector is read-only and cannot be erased or programmed. Each sector can be independently programmed for either the Softlock or Hardlock sector protection mode. At power-up and reset, all sectors have their Softlock protection mode enabled.
4.8.1
Softlock and Unlock The Softlock protection mode can be disabled by issuing a two-bus cycle Unlock command to the selected sector. Once a sector is unlocked, its contents can be erased or programmed. To enable the Softlock protection mode, a two-bus cycle Softlock command must be issued to the selected sector. Hardlock and Write Protect The Hardlock sector protection mode operates in conjunction with the Write Protect (WP) pin. The Hardlock sector protection mode can be enabled by issuing a two-bus cycle Hardlock Software command to the selected sector. The state of the Write Protect pin affects whether the Hardlock protection mode can be overridden. * When the WP pin is low and the Hardlock protection mode is enabled, the sector cannot be unlocked and the contents of the sector is read-only. * When the WP pin is high, the Hardlock protection mode is overridden and the sector can be unlocked via the Unlock command. To disable the Hardlock sector protection mode, the chip must be either reset or power cycled.

Sector Protection Detection A software method is available to determine if the sector protection Softlock or Hardlock features are enabled. When the device is in the software product identification mode, a read from the I/O0 and I/O1 at address location 00002H within a sector will show if the sector is unlocked, softlocked, or hardlocked.

Erase Suspend/Erase Resume
The Erase Suspend command allows the system to interrupt a sector erase operation and then program or read data from a different sector within the memory. After the Erase Suspend command is given, the device requires a maximum time of 15 s to suspend the erase operation. After the erase operation has been suspended, the system can then read data or program data to any other sector within the device. An address is not required during the Erase Suspend command. During a sector erase suspend, another sector cannot be erased. To resume the sector erase operation, the system must write the Erase Resume command. The Erase Resume command is a one-bus cycle command. The only valid commands while erase is suspended are Read Status Register, Product ID Entry, CFI Query, Program, Program Resume, Erase Resume, Sector Softlock/Hardlock, Sector Unlock.
4.10
Program Suspend/Program Resume
The Program Suspend command allows the system to interrupt a programming operation and then read data from a different word within the memory. After the Program Suspend command is given, the device requires a maximum of 20 s to suspend the programming operation. After the programming operation has been suspended, the system can then read data from any other word within the device. An address is not required during the program suspend operation. To resume the programming operation, the system must write the Program Resume command. The program suspend and resume are one-bus cycle commands. The command sequence for the erase suspend and program suspend are the same and the command sequence for the erase resume and program resume are the same. The only other valid commands while program is suspended are Read Status Register, Product ID Entry, CFI Query and Program Resume.
4.11
Product Identification
The product identification mode identifies the device and manufacturer as Atmel. It may be accessed by a software operation. For details, see "Operating Modes" on page 21.
4.12
128-bit Protection Register
The AT49BV320D(T) contains a 128-bit register that can be used for security purposes in system design. The protection register is divided into two 64-bit sectors. The two sectors are designated as sector A and sector B. The data in sector A is non-changeable and is programmed at the factory with a unique number. The data in sector B is programmed by the user and can be locked out such that data in the sector cannot be reprogrammed. To program sector

AT49BV320D(T)
3581C-FLASH-11/05
AT49BV320D(T)
B in the protection register, the two-bus cycle Program Protection Register command must be used as shown in the "Command Definition Table" on page 15. To lock out sector B, the two-bus cycle Lock Protection Register command must be used as shown in the "Command Definition Table" . Data bit D1 must be zero during the second bus cycle. All other data bits during the second bus cycle are don't cares. To determine whether sector B is locked out, use the status of sector B protection command. If data bit D1 is zero, sector B is locked. If data bit D1 is one, sector B can be reprogrammed. Please see the "Protection Register Addressing Table" on page 16 for the address locations in the protection register. To read the protection register, the Product ID Entry command is given followed by a normal read operation from an address within the protection register. After determining whether sector B is protected or not, or reading the protection register, the Read command must be given to return to the read mode.
4.13
Common Flash Interface (CFI)
CFI is a published, standardized data structure that may be read from a flash device. CFI allows system software to query the installed device to determine the configurations, various electrical and timing parameters and functions supported by the device. CFI is used to allow the system to learn how to interface to the flash device most optimally. The two primary benefits of using CFI are ease of upgrading and second source availability. The command to enter the CFI Query mode is a one-bus cycle command which requires writing data 98h to any address. The CFI Query command can be written when the device is ready to read data or can also be written when the part is in the product ID mode. Once in the CFI Query mode, the system can read CFI data at the addresses given in "Common Flash Interface Definition Table" on page 27. To return to the read mode, issue the Read command.
4.14
Hardware Data Protection
The Hardware Data Protection feature protects against inadvertent programs to the AT49BV320D(T) in the following ways: (a) VCC sense: if VCC is below 1.8V (typical), the program function is inhibited. (b) VCC power-on delay: once VCC has reached the VCC sense level, the device will automatically time out 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Program inhibit: VPP is less than VILPP.
4.15
Input Levels
While operating with a 2.65V to 3.6V power supply, the address inputs and control inputs (OE, CE and WE) may be driven from 0 to 5.5V without adversely affecting the operation of the device. The I/O lines can only be driven from 0 to VCCQ + 0.6V.
4.16
Output Levels
For the AT49BV320D(T), output high levels (VOH) are equal to VCCQ - 0.1V (not VCC). For 2.65V - 3.6V output levels, VCCQ must be tied to VCC.

Address A20 through A8 are don't care. 2. SA = sector address. Any word address within a sector can be used to designate the sector address (see pages 17 - 20 for details). 3. This fast programming option enables the user to program two words in parallel only when VPP = 9.5V. The addresses, Addr0 and Addr1, of the two words, DIN0 and DIN1, must only differ in address A0. This command should be used during manufacturing purposes only. 4. The status register bits are output on I/O7 - I/O0. 5. Any addresses within the user programmable protection register region. Address locations are shown on "Protection Register Addressing Table" on page 16. 6. If data bit D1 is "0", sector B is locked. If data bit D1 is "1", sector B can be reprogrammed.
