*1 : In CE1s controlled data retention mode, input level of CE2s should be fixed Vccs to Vccs–0.2 V or Vss
to 0.2 V during data retention mode. Other input and input/output pins can be used between –0.3 V to
Vccs+0.3 V.
*2 : When CE1s is operating at the VIH Min level (2.2 V), the standby current is given by ISB1s during the
transition of VCCs from 3.3 V to 2.2 V.
