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. FEATURES • Fast access times of 90ns, 120ns, and 150ns • 5.0V ±10%, single power supply operation • Low power consumption typical: 4µA typical CMOS stand-by * ICC(active) <120mA for READ/WRITE • 20 year DATA RETENTION at 125oC • 1,000,000 program/erase cycles • 16 equal sectors of 64 Kbytes each • Any combination of sectors can be erased • Group sector protection • Supports FULL chip erase • Compatible with JEDEC standards • Embedded erase and program algorithms • Data polling and toggle bits for detection of program or erase cycle completion. • Erase suspend/resume • Hardware reset pin (RESET) • Built in decoupling caps and multiple ground pins for low noise operation • Separate power and ground planes to improve noise immunity
