Description

The Hitachi HM51(S)4170C are CMOS dynamic RAM organized as 262,144-word ×16-bit. It has realized higher density, higher performance and various functions by employing 0.8 mm CMOS process technology and some new CMOS circuit design technologies. It offers fast page mode as a high speed access mode. Multiplexed address input permits the HM51(S)4170C to be packaged in standard 400-mil 40-pin plastic SOJ and standard 400-mil 44-pin plastic TSOPII. Internal refresh timer enables HM51S4170C self refresh operation.
