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.
