NOTES:

1) ICC1T and ICC2T are specified with CE set to a logic 0.

2) ICC1A and ICC2A are specified with CE = VCC, SCLK = 2MHz at VCC = 5V; SCLK = 500kHz at VCC =

2.0V, VIL = 0V, VIH = VCC.

3) Measured at VIH = 2.0V or VIL = 0.8V and 10ms maximum rise and fall time.

4) Measured with 50pF load.

5) Measured at VOH = 2.4V or VOL = 0.4V.

6) VCC = VCC1, when VCC1 > VCC2 + 0.2V (typical); VCC = VCC2, when VCC2 > VCC1.

7) VCC2 = 0V.

8) VCC1 = 0V.

9) VCC1 < VBAT.

10) VCCIF must be less than or equal to the largest of VCC1, VCC2, and VBAT.
