21, 1995 Description The Hitachi HM51(S)4170C are CMOS dynamic RAM organized as 262,144-word × 16-bit.
HM51(S)4170C have realized higher density, higher performance and various functions by employing 0.
8 µm CMOS process technology and some new CMOS circuit design technologies.
The HM51(S)4170C offer 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.
Features • • • Single 5 V ( ±10%) High speed — Access time: 70 ns/80 ns (max) Low power dissipation — Active mode: 660 mW/578 mW (max) — Standby mode: 11 mW (max) 1.
