HM628128D Series
1 M SRAM (128-kword × 8-bit)
ADE-203-996 (Z)
Preliminary, Rev. 0.0
Jan. 20, 1999
Description
The Hitachi HM628128D Series is 1-Mbit static RAM organized 131,072-kword × 8-bit. HM628128D
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
Active: 30 mW/MHz (typ)
Standby: 10 µW (typ)
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
Battery backup operation
2 chip selection for battery backup
