AT49BV321T-11CI Datasheet


The AT49BV/LV32X T is a 3.0-volt 32-megabit Flash memor y organized as 2,097,152 words of 16 bits each or 4,194,304 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 48-lead TSOP, and 48-ball CBGA and µBGA packages. 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.
