HM-65642
8K x 8 Asynchronous
CMOS Static RAM
Description
The HM-65642 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 is ideally
suited for use in microprocessor based systems. In particu-
lar, interfacing with the Intersil 80C86 and 80C88 micropro-
cessors is simplified by the convenient output enable (G)
input.
The HM-65642 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.
