1. Description

The AT49BV322A(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

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.
