Note 26. Typical parameter indicates the value for the center of distribution at 3.0V (Ta=25ºC), and not 100% tested.
27. CS# controls address buffer, WE# buffer, OE# buffer, LB# buffer, UB# buffer and I/O buffer. If CS# controls
data retention mode, Vin levels (address, WE#, OE#, LB#,UB#, I/O) can be in the high-impedance state.
