M48Z32V
WRITE Mode
The M48Z32V is in the WRITE Mode whenever W
and E are low. The start of a WRITE is referenced
from the latter occurring falling edge of W or E. A
WRITE is terminated by the earlier rising edge of
W or E. The addresses must be held valid through-
out the cycle. E or W must return high for a mini-
mum of t
EHAX
from Chip Enable or t
WHAX
from
WRITE Enable prior to the initiation of another
READ or WRITE cycle. Data-in must be valid t
D-
VWH
prior to the end of WRITE and remain valid for
t
WHDX
afterward. G should be kept high during
WRITE cycles to avoid bus contention; although, if
the output bus has been activated by a low on E
and G, a low on W will disable the outputs t
WLQZ
after W falls.
