Description
The AT49BV/LV16X(T) is a 3.0-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 a 48-lead TSOP, 45-ball 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.
