Description
The AT49BV162A(T)/163A(T) is a 2.7-volt 16-megabit Flash memory organized as
1,048,576 words of 16 bits each or 2,097,152 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 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.
