HM628100I Series Wide Temperature Range Version 8 M SRAM (1024-kword × 8-bit) ADE-203-1302B (Z) Rev. 1.0 Sep. 25, 2002 Description The Hitachi HM628100I Series is 8-Mbit static RAM organized 1,048,576-word × 8-bit. HM628100I Series has realized higher density, higher performance and low power consumption by employing CMOS process technology (6-transistor memory cell). It offers low power standby power dissipation; therefore, it is suitable for battery backup systems. It is packaged in standard 44-pin TSOP II for high density surface mounting. Features • • • Single 5.0 V supply: 5.0 V ± 10 % Fast access time: 55 ns (max) Power dissipation:  Active: 10 mW/MHz (typ)  Standby: 7.5 µW (typ) Completely static memory.
