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, flexible 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 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.

The write cycle is initiated on the falling edge of E (T = 0),
which latches the address information in the on-chip
registers. If a write cycle is to be performed where the output
is not to become active, G can be held high (inactive).
TDVWH and TWHDX must be met for proper device opera-
tion regardless of G. If E and G fall before W falls (read
mode), a possible bus conflict may exist. If E rises before W
rises, reference data setup and hold times to the E rising
edge. The write operation is terminated by the first rising edge
of W (T = 2) or E (T = 3). After the minimum E high time
(TEHEL), the next cycle may begin. If a series of consecutive
write cycles are to be performed, the W line may be held low
until all desired locations have been written. In this case, data
setup and hold times must be referenced to the rising of E.
