Description
The Hitachi HM628128D Series is 1-Mbit static RAM organized 131,072-kword
Series has realized higher density, higher performance and low power consumption by employing Hi-
CMOS process technology. The HM628128D Series offers low power standby power dissipation;
therefore, it is suitable for battery backup systems. It has package variations of standard 32-pin plastic DIP,
standard 32-pin plastic SOP and standard 32-pin plastic TSOPI.
Features
Single 5 V supply: 5 V 10%
Access time: 55 ns/70 ns (max)
Power dissipation
Completely static memory.
Equal access and cycle times
Common data input and output
Directly TTL compatible all inputs
Battery backup operation
Active: 30 mW/MHz (typ)
Standby: 10 W (typ)
No clock or timing strobe required
Three state output
2 chip selection for battery backup
1 M SRAM (128-kword
