2. All address inputs must meet the specified setup and hold times for all rising clock(CLK) edges when ADV is sampled low and CS is sampled
3. Chip selects must be valid at each rising edge of CLK(when ADV is Low) to remain enabled.
4. A write cycle is defined by WE low having been registered into the device at ADV Low, A Read cycle is defined by WE High with ADV Low,
5. To avoid bus contention, At a given voltage and temperature t
It is not possible for two SRAMs on the same board to be at such different voltage and temperature.
low. All other synchronous inputs must meet the specified setup and hold times whenever this device is chip selected.
The specs as shown do not imply bus contention because t
(0 C,3.465V) than t
Both cases must meet setup and hold times.
