HM62256A Series 32,768-word × 8-bit High Speed CMOS Static RAM The Hitachi HM62256A is a CMOS static RAM organized 32-kword × 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 × 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. Maintenance only Ordering Information Type No.
