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.
