NOTES:
1. All read and write cycles are referenced from K.
2. Valid data from clock high will be the data stored at the address or the last valid read cycle.
3. Measured at
±
200 mV from steady state.
4. This is a synchronous device. All synchronous inputs must meet the specified setup and hold times with stable logic levels for
ALL
rising
edges of clock (K) while the device is selected.
