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 HiCMOS 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.
