HM5164805F Series HM5165805F Series
64 M EDO DRAM (8-Mword × 8-bit) 8 k Refresh/4 k Refresh
ADE-203-1057B (Z) Rev. 2.0 Nov. 30, 1999 Description
The Hitachi HM5164805F Series, HM5165805F Series are 64M-bit dynamic RAMs organized as 8,388,608-word × 8-bit. They have realized high performance and low power by employing CMOS process technology. HM5164805F Series, HM5165805F Series offer Extended Data Out (EDO) Page Mode as a high speed access mode. They have the package variation of standard 32-pin plastic SOJ and standard 32pin plastic TSOPII.
