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 sectors for

erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA pack-

age. 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.
