Atmel AT49BV320D(T) Flash Memory Datasheet

The AT49BV320D(T) is a 2.7V 32-megabit Flash memory organized as 2,097,152 words of 16 bits each. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP package and a 47-ball CBGA package. 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. The device powers on in the read mode. Command sequences are used to place the device in other operating modes.
