www.DataSheet4U.com ADE-XXX-XXX HM628128A Series 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. Features High speed — Fast access time: 55/70/85/100 ns (max) Low power — Active: 75 mW (typ) It offers low power standby power dissipation; therefore, it is suitable for battery back-up systems. — Standby: 10 µW (typ) The device, packaged in a 525-mil SOP (460-mil Single 5 V supply body SOP) or a 600-mil plastic DIP, or a 8 × 20 Completely static memory mm TSOP with thickness of 1.2 mm, is available No clock or timing strobe required for high density mounting. TSOP package is suitable for cards, and reverse type TSOP is also Equal access and cycle times provided.
