Low power clock/calendar

PCF8593

Notes

1. Typical values measured at Tamb =25 °C.

2. When powering up the device, VDD must exceed the specified minimum value by 300 mV to guarantee correct

start-up of the oscillator.

3. Event counter mode: supply current dependent upon input frequency.

4. Tested on sample basis.
