The Hitachi HM62256A is a CMOS static RAM organized 32-kword x 8-bit. It realizes higher performance and low power consumption by employing 0.8 µm Hi-CMOS process technology. The device, packaged in a 8 x 14 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. TSOP package is suitable for cards, and reverse type TSOP is also provided. It offers low power standby power dissipation; therefore, it is suitable for battery back up system.
Features: * High speed: Fast Access time 85/100/120/150 ns (max) * Low Power Standby: 5 µW (typ) (L/L-SL version) Operation: 40 mW (typ) (f = 1 MHz) * 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 back up operation
