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 particu-

lar, interfacing with the Intersil 80C86 and 80C88 micropro-

cessors 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 mili-

tary temperature range.
