ADE-203-188H(Z)
HM658128A Series
131072-word × 8-bit High Speed CMOS Pseudo Static
RAM
Rev. 8.0
Jun. 5, 1995
The Hitachi HM658128A is a pseudo-static RAM
organized as 131,072-word × 8-bit. HM658128A
realizes low power consumption and high speed
www.DataShaececte4sUs.ctoimme by employing 1.3 µm CMOS process
technology. The HM658128A supports 3 refresh
functions: address refresh, auto refresh and self
refresh. Low power version dissipates only
350 µW (typ)/500 µW (typ) in self refresh mode
and retains the data with battery. The
HM658128A is pin-compatible with 1-Mbit static
RAM.
