TIMING WAVEFORM OF WRITE CYCLE NO. 2 (

CONTROLLED TIMING)
(1, 2, 3, 5)
NOTES:
1.
WE
or
CS
must be high during all address transitions.
2. A write occurs during the overlap (t
WP
) of a low
CS
and a low
WE
.
3. t
WR
is measured from the earlier of
CS
or
WE
going high to the end of write cycle.
4. During this period, I/O pins are in the output state, and input signals must not be applied.
5. If the
CS
low transition occurs simultaneously with or after the
WE
low transition, the outputs remain in a high impedance state.
6. Transition is measured
±
200mV from steady state with a 5pF load (including scope and jig). This parameter is guaranteed by design, but not tested.
7. If
OE
is low during a
WE
controlled write cycle, the write pulse width must be the larger of t
WP or (
t
WHZ +
t
DW)
.
