Notes :
1. Transition is measured
± 500 mV from low or high impedance voltage with load (figures 2 and 3).
2. This parameters is guaranteed but not tested.
3. To access RAM CS = VIL, UB or LB = VIL, SEM = VIH. To access semaphore CS = VIH, SEM = VIL. This condition must be valid
for entire tSW time.
4. The specification for tDH must be met by the device supplying write data to the RAM under all operating conditions. Although tDH
and tOW values will vary over voltage and temperature, the actual tDH will always be smaller than the actual tOW.
5. STD symbol.
6. ALT symbol.
