HM62256AP-12

HM62256AP-12 芯片功能简介

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 ?m 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.
Features
? High speed: Fast Access time 85/100/120/150 ns
(max)
? Low Power
Standby: 5 ?W (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
