HM62864

HM62864 Series 65536-word × 8-bit High Speed CMOS Static RAM ADE-203-255B (Z) Rev. 2.0 Jul. 4, 1995 Description The Hitachi HM62864 is a CMOS static RAM organized 64-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 backup systems. The device, packaged in a 525-mil SOP (460-mil body SOP) and a 8 × 20 mm TSOP with thickness of 1.2 mm, is available for high density mounting. TSOP package is suitable for cards. Features High speed — Fast access time: 55/70/85 ns (max) Low power — Active: 50 mW (typ) (f = 1 MHz) — Standby: 2 µW (typ) Single 5 V supply Completely static memory No clock or timing strobe required Equal access and cycle times Common data input and output Three state output Directly TTL compatible All inputs and outputs Capability of battery backup operation 2 chip se...
