8kx8 Asynchronous CMOS Static RAM
Jump to Page Section:
Overview
Description
The HM-65642/883 is a CMOS 8192 x 8-bit Static Random Access Memory. The pinout is the JEDEC 28 pin, 8-bit wide standard, which allows easy memory board layouts which accommodate a variety of industry standard ROM, PROM, EPROM, EEPROM and RAMs. The HM-65642/883 is ideally suited for use in microprocessor based systems. In particular, interfacing with the Renesas 80C86 and 80C88 microprocessors is simplified by the convenient output enable (G) input. The HM-65642/883 is a full CMOS RAM which utilizes an array of six transistor (6T) memory cells for the most stable and lowest possible standby supply current over the full military temperature range.
