Description

The AT49BV/LV32X(T) is a 3.0-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 48-lead TSOP, and

48-ball CBGA and µBGA packages. 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.
