M68AW031A
Write Mode
The M68AW031A is in the Write mode whenever
the W and E are Low. Either the Chip Enable input
(E) or the Write Enable input (W) must be de-
asserted
during
Address
subsequent write cycles. When E (W) is Low, write
cycle begins on the W (E)’s falling edge.
Therefore, address setup time is referenced to
Write Enable or Chip Enable as t
AVWL
and t
AVEL
respectively, and is determined by the latter
occurring edge.
transitions
for
The Write cycle can be terminated by the earlier
rising edge of E or W.
If the Output is enabled (E = Low, G = Low), then
W will return the outputs to high impedance within
t
WLQZ
of its falling edge. Care must be taken to
avoid bus contention in this type of operation. Data
input must be valid for t
DVWH
before the rising
edge of Write Enable, or for t
DVEH
before the rising
edge of E, whichever occurs first, and remain valid
for t
WHDX
and t
EHDX
respectively.
