Description

The Hitachi HM62256B is a CMOS static RAM organized 32-kword×8-bit. It realizes higher performance and low power consumption by employing 0.8 mm Hi-CMOS process technology. HM62256B, packaged in 8 ×14 mm TSOP, 8 ´ 13.4 mm TSOP with thickness of 1.2 mm, 450-mil SOP (foot print pitch width), 600-mil plastic DIP, or 300-mil plastic DIP, is available for high density mounting. HM62256B offers low power standby power dissipation; therefore, it is suitable for battery back-up systems.
