1. Description

The AT49BV322D(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152

words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on

I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sec-

tors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball

CBGA package. The device has CE and OE control signals to avoid any bus conten-

tion. 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

“Sector Lockdown” on page 7).

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 end of a program or an erase cycle is detected by the

READY/BUSY pin, Data Polling or by the toggle bit.

puts. 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.

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 or standby mode,

depending upon the state of the control inputs.

4.4

Erase

Before a byte/word can be reprogrammed, it must be erased. The erased state of memory bits is

a logical “1”. The entire device can be erased by using the Chip Erase command or individual

sectors can be erased by using the Sector Erase command.

4.4.1

Chip Erase

The entire device can be erased at one time by using the six-byte chip erase software code.

After the chip erase has been initiated, the device will internally time the erase operation so that

no external clocks are required. The maximum time to erase the chip is t

If the sector lockdown has been enabled, the chip erase will not erase the data in the sector that

has been locked out; it will erase only the unprotected sectors. After the chip erase, the device

will return to the read or standby mode.

4.4.2

Sector Erase

As an alternative to a full chip erase, the device is organized into 71 sectors (SA0 - SA70) that

can be individually erased. The Sector Erase command is a six-bus cycle operation. The sector

address is latched on the falling WE edge of the sixth cycle while the 30H data input command is

latched on the rising edge of WE. The sector erase starts after the rising edge of WE of the sixth

cycle. The erase operation is internally controlled; it will automatically time to completion. The

maximum time to erase a sector is t

SEC

. When the sector programming lockdown feature is not

enabled, the sector will erase (from the same Sector Erase command). An attempt to erase a

sector that has been protected will result in the operation terminating immediately.

4.5

Byte/Word Programming

Once a memory block is erased, it is programmed (to a logical “0”) on a byte-by-byte or on a

word-by-word basis. Programming is accomplished via the internal device command register

and is a four-bus cycle operation. The device will automatically generate the required internal

program pulses.

Any commands 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 opera-

tions can convert “0”s to “1”s. Programming is completed after the specified t

cycle time. The

Data Polling feature or the Toggle Bit feature may be used to indicate the end of a program

cycle. If the erase/program status bit is a “1”, the device was not able to verify that the erase or

program operation was performed successfully.
