READ mode AC characteristics
WRITE mode
The M48Z08/18 is in the WRITE mode whenever W and E are active. 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 throughout the cycle. E or W must return high for a minimum of t
or t
in must be valid t
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
falls.
