NOTES:

1. All voltages are referenced to ground.

2. Logic 1 voltages are specified at VCC = 3.3V, VOH = VCC for capacitive loads. Excludes RST pin.

3. Logic 0 voltages are specified at VCC = 3.3V, VOL = GND for capacitive loads.

4. ICCA is specified with outputs open, CS set to a logic 1, SCLK = 500kHz, oscillator enabled, and

DAC enabled.

5. IADC is specified with CS, VCCO open and I/O, SCLK at logic 0. ADC is enabled.

6. ICCS is specified with CS, VCCO open and I/O, SCLK at logic 0. ADC is disabled.

7. CS has a 40k pulldown resistor to ground.

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

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

10. Load capacitance = 50 pF.

11. ICCO = 100 mA, VCC > VCCTP.

12. VCCO switchover from VCC to VBAT occurs when VCC drops below the lower of VCCSW and VBAT.

13. Current from VCC input pin to VCCO output pin.

14. Current from VBAT input pin to VCCO output pin.

15. Time base is generated by very accurate crystal oscillator. Accuracy of this time period is based on

the crystal that is used. A typical crystal with a specified load capacitance of 6pF will provide an

accuracy within ±100ppm over the 0°C to +70°C temperature range.

16. If the EOSC bit in the Control Register is set to a logic 1, tRPU is equal to 250ms plus the startup time

of the crystal oscillator.
