Description
The HM-65162 is a CMOS 2048 x 8 Static Random Access
Memory manufactured using the Intersil Advanced SAJI V
process. The device utilizes asynchronous circuit design for
fast cycle time and ease of use. The pinout is the JEDEC 24
pin DIP, and 32 pad 8-bit wide standard which allows easy
memory board layouts flexible to accommodate a variety of
industry standard PROMs, RAMs, ROMs and EPROMs. The
HM-65162 is ideally suited for use in microprocessor based
systems with its 8-bit word length organization. The conve-
nient output enable also simplifies the bus interface by allow-
ing the data outputs to be controlled independent of the chip
enable. Gated inputs lower operating current and also elimi-
nate the need for pull-up or pull-down resistors.

Timing Waveforms
Addresses must remain stable for the duration of the read
cycle. To read, G and E must be
V
IL
and W
V
IH
. The
output buffers can be controlled independently by G while E
is low. To execute consecutive read cycles, E may be tied
low continuously until all desired locations are accessed.
To write, addresses must be stable, E low and W falling low
for a period no shorter than TWLWH. Data in is referenced
with the rising edge of W, (TDVWH and TWHDX). While
addresses are changing, W must be high. When W falls low,
the I/O pins are still in the output state for a period of TWLQZ
and input data of the opposite phase to the outputs must not
be applied, (Bus contention). If E transitions low
simultaneously with the W line transitioning low, or after the
W transition, the output will remain in a high impedance
state. G is held continuously low.
