GENERAL DESCRIPTION

The Austin Semiconductor, Inc. AS8F1M32 is a 32 Mbit, 5.0 voltonly Flash memory. This device is designed to be programmed insystem with the standard system 5.0 volt VCC supply. The AS8F1M32 offers an access time of 90ns, allowing high-speed microprocessors to operate without wait states. To eliminate bus contention, the device has separate chip enable (CE), write enable (WE) and output enable (OE) controls.
