Description

The Hitachi HM62W8128B is a CMOS static RAM organized 131,072-word ×8-bit. It realizes higher density, higher performance and low power consumption by employing 0.8 mm Hi-CMOS shrink process technology. HM62W8128B 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) or a 8 mm ×20 mm TSOP with thickness of 1.2 mm, is available for high density mounting. TSOP package is suitable for cards, and reverse type TSOP is also provided.
