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 a LOW
CE
and a LOW R/
W
for memory array writing cycle.
3. t
WR
is measured fromthe earlier of
CE
or R/
W
(or
SEM
or R/
W
) going HIGH to the end of write cycle.
4. During this period, the I/O pins are in the output state and input signals must not be applied.
5. If the
CE
or
SEM
LOW transition occurs simultaneously with or after the R/W low transition, the outputs remain in the High-impedance state.
6. Timng depends on which enable signal is asserted last,
CE
, or R/
W
.
7. Timng depends on which enable signal is de-asserted first,
CE
, or R/
W
.
8. If
OE
is LOW during 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 an R/
W
controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified t
WP
.
9. To access SRAM
CE
= V
IL
and
SEM
= V
IH
. To access Semaphore,
CE
= V
IH
and
SEM
= V
IL
. t
EW
must be met for either condition.
