HM-6516
March 1997
2K x 8 CMOS RAM
Description
The HM-6516 is a CMOS 2048 x 8 Static Random Access
Memory. Extremely low power operation is achieved by the
use of complementary MOS design techniques. This low
power is further enhanced by the use of synchronous circuit
techniques that keep the active (operating) power low, which
also gives fast access times. The pinout of the HM-6516 is
the popular 24 pin, 8-bit wide JEDEC standard, which allows
easy memory board layouts, 鏗俥xible enough to accommo-
date a variety of PROMs, RAMS, EPROMs, and ROMs.
The HM-6516 is ideally suited for use in microprocessor
based systems. The byte wide organization simpli鏗乪s the
memory array design, and keeps operating power down to a
minimum, because only one device is enabled at a time. The
address latches allow very simple interfacing to recent gen-
eration microprocessors which employ a multiplexed
address/data bus. The convenient output enable control also
simpli鏗乪s multiplexed bus interfacing by allowing the data
outputs to be controlled independent of the chip enable.
