Description
The AT49BV/LV16X4A(T) is a 2.65- to 3.3-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 39 sectors for erase operations. The device is offered in 48-lead TSOP and
48-ball CBGA packages. The device has CE and OE control signals to avoid any bus
contention. This device can be read or reprogrammed using a single 2.65V power
supply, making it ideally suited for in-system programming.
