Product Summary
The Hitachi HM62256BLP is a CMOS static RAM organized 32,768-word×8-bit. It realizes higher performance and low power consumption by employing 0.8 mm Hi-CMOS process technology. The HM62256BLP, 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. The HM62256BLP offers low power standby power dissipation; therefore, it is suitable for battery backup systems.
