TIMING WAVEFORM OF WRITE CYCLE NO. 2, (
CE
CONTROLLED TIMING)
(1,5)
NOTES:
1. R/
W
or
CE
must be High during all address transitions.
2. A write occurs during the overlap (t
EW
or t
WP
) of
CE
=
V
IL
and R/
W
=
V
IL.
3. t
WR
is measured from the earlier of
CE
or R/
W
going High to the end of the write cycle.
4. During this period, the l/O pins are in the output state and input signals must not be applied.
5. If the
CE
Low transition occurs simultaneously with or after the R/
W
Low transition, the outputs remain in the High-impedance state.
6. Timing depends on which enable signal (
CE
or R/
W
) is asserted last.
7. This parameter is determined be device characterization, but is not production tested. Transition is measured +/- 500mV from steady state
with the Output Test Load (Figure 2).
8. If
OE
is low during a R/
W
controlled write cycle, the write pulse width must be the larger of t
WP
or (t
WZ
+ t
DW
) to allow the I/O drivers to turn off
and data to be placed on the bus for the required t
DW
. If
OE
is High during a R/
W
controlled write cycle, this requirement does not apply and
the write pulse can be as short as the specified t
WP
.
