131,072-word × 8-bit High Speed CMOS Static RAM

Rev. X

January 1995

The Hitachi HM628128A is a CMOS static RAM

organized 128 kword × 8 bit. It realizes higher

density, higher performance and low power

consumption by employing 0.8 µm 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 × 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.
