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.
