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. In addition to this, the high stability
of the 6T RAM cell provides excellent protection against soft
errors due to noise and alpha particles. This stability also
improves the radiation tolerance of the RAM over that of four
transistor or MIX-MOS (4T) devices
