OPERATING CONDITIONS (cont’d)
The RC oscillator and PLL characteristics are temperature-dependent.
13.3.1.1 Operating Conditions (tested for TA = -40 to +125°C) @ VDD = 4.5 to 5.5V
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.
3. Minimum 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 1 MHz.
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 maximum 10% until tSTAB has elapsed. See Figure 11 on page 22.
