Description

The Hitachi HM51(S)4800C are CMOS dynamic RAM organized as 524,288-word ×8-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. The HM51(S)4800C offer Fast Page Mode as a high speed access mode. Multiplexed address input permits the HM51(S)4800C to be packaged in standard 400-mil 28-pin plastic SOJ and standard 400-mil 28-pin plastic TSOPII. Internal refresh timer enables HM51S4800C self refresh operation.
