The Hitachi HM628128A is a CMOS static RAM
organized 128 kword
脳
8 bit. It realizes higher
density, higher performance and low power
consumption by employing 0.8 碌m Hi-CMOS
process technology.
It offers low power standby power dissipation;
therefore, it is suitable for battery back-up systems.
The device, packaged in a 525-mil SOP (460-mil
body SOP) or a 600-mil plastic DIP, or a 8
脳
20
mm TSOP with thickness of 1.2 mm, is available
for high density mounting. TSOP package is
suitable for cards, and reverse type TSOP is also
provided.
