Notes:

1. If the RC oscillator clock is selected, to improve clock stability and frequency accuracy, it is recommended to place a

decoupling capacitor, typically 100nF, between the VDD and VSS pins as close as possible to the ST7 device.

2. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 23

3. Min value is obtained for hot temperature and max value is obtained for cold temperature.

4. Data based on characterization results, not tested in production

5. Measurement made with RC calibrated at 1MHz.

6. Guaranteed by design.

7. Averaged over a 4ms period. After the LOCKED bit is set, a period of tSTAB is required to reach ACCPLL accuracy.

8. After the LOCKED bit is set ACCPLL is max. 10% until tSTAB has elapsed. See Figure 12 on page 24.
