IDT7188S/L
CMOS Static RAM 64K (16K x 4-Bit) Military Temperature Range
Timing Waveform of Write Cycle No. 1 (
WE
Controlled Timing)
(1,2,3)
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 fromthe 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 should not be applied.
5. If the
CS
LOW transition occurs simultaneously with or after the
WE
LOW transition, the outputs remain in the high-impedance state.
6. Transition is measured ±200mV fromsteady state.
