INDUSTRIAL AND COMMERCIAL TEMPERATURE RANGES
TIMING WAVEFORM OF WRITE CYCLE NO. 2 (
CS
CONTROLLED TIMING)
(1, 2, 3, 4)
NOTES:
1.
WE
or
CS
must be HIGH during all address transitions.
2. A write occurs during the overlap 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 the write cycle.
4. If the
CS
LOW transition occurs simultaneously with or after the
WE
LOW transition, the outputs remain in a high-impedance state.
5. 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
) 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
WE
controlled write cycle, this requirement does not apply and the write pulse can
be as short as the spectified t
WP.
