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 32-
pin plastic TSOPII.
