HM62V16256CI Series Wide Temperature Range Version 4 M SRAM (256-kword × 16-bit) ADE-203-1230A (Z) Rev. 1.0 Feb. 6, 2001 Description The Hitachi HM62V16256CI Series is 4-Mbit static RAM organized 262,144-word × 16-bit. HM62V16256CI 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 plastic TSOPII.
