The HM-6516/883 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 cir-
cuit techniques that keep the active (operating) power low,
which also gives fast access times. The pinout of the HM-
6516/883 is the popular 24 pin, 8-bit wide JEDEC Standard
which allows easy memory board layouts, flexible enough to
accommodate a variety of PROMs, RAMS, EPROMs, and
ROMs.
The HM-6516/883 is ideally suited for use in microprocessor
based systems. The byte wide organization simplifies 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
simplifies multiplexed bus interfacing by allowing the data
outputs to be controlled independent of the chip enable.
