NOTES

1. All voltages are referenced to ground.

2. Logic 0 voltages are specified at a sink current of 4 mA at VCC =5V and 1.5 mA at VCC =2.0V, VOL

=GND for capacitive loads.

3. ICC1T and ICC2T are specified with CE set to a logic 0 and EOSC bit=0 (oscillator enabled).

4. ICC1A and ICC2A are specified with CE=VCC, SCLK=2 MHz (0-VCC) at VCC =5V; SCLK=500 kHz

(0-5V) at VCC =2.0V and EOSC bit=0 (oscillator enabled).

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

6. Measured with 50 pF load.

7. Measured at VOH =2.4V or VOL =0.4V.

8. ICC1S and ICC2S are specified with CE set to a logic 0. The EOSC bit must be set to logic 1 (oscillator

disabled).

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

10. VCC2 =0V.

11. VCC1 =0V.

12. VCC1<VBAT.

13. Logic one voltages are specified at a source current of 1 mA at VCC =5V and 0.4 mA at 2.0V, VOH

=VCC.

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