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.AT49BV1614A can be read or reprogrammed using a single 2.65V power supply, making it ideally suited for in-system programming.
