IDT71V256SA
3.3V CMOS STATIC RAM 256K (32K x 8-BIT)
INDUSTRIAL AND COMMERCIAL TEMPERATURE RANGES
TIMING WAVEFORM OF READ CYCLE NO. 2
(1, 2, 4)
TIMING WAVEFORM OF READ CYCLE NO. 3
(1, 3, 4)
NOTES:
1.
WE
is HIGH for Read cycle.
2. Device is continuously selected,
CS
is LOW.
3. Address valid prior to or coincident with
CS
transition LOW.
4.
OE
is LOW.
5. Transition is measured
±
200mV from steady state.
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. During this period, I/O pins are in the output state so that the 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.
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
) 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.
