HM4-65642B Overview

8K x 8 Asynchronous CMOS Static RAM

®
HM-65642/883
8K x 8 Asynchronous
CMOS Static RAM
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.
