Description
The AT49BV16X4(T) is 2.7 to 3.6 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 40 blocks for erase operations. The device is offered in 48-pin TSOP and 48-ball
µBGA packages. The device has CE, and OE control signals to avoid any bus con-
tention. This device can be read or reprogrammed using a single 2.7V power supply,
making it ideally suited for in-system programming.
