Note 1.Typical parameter indicates the value for the center of distribution at 3.0V(Ta=+25°C), and not 100% tested.
2.Typical parameter indicates the value for the center of distribution at 3.0V(Ta=+40°C), and not 100% tested.
3.CS2 controls address buffer, WE# buffer, CS1# Buffer, OE# buffer, LB#, UB# buffer and Din buffer.
If CS2 controls data retention mode, Vin levels (address, WE#, OE#, LB#, UB#, DQ) can be in the high
impedance state. If CS1# controls data retention mode, CS2 must be CS2 ⥠VCC-0.2V or 0V ⤠CS2 ⤠0.2V .
The other inputs levels (address, WE#, OE#, CS1#, LB#, UB#, DQ) can be in the high impedance state.
