13.3.4 Internal RC Oscillator and PLL
The ST7 internal clock can be supplied by an internal RC oscillator and PLL (selectable by option byte).
The RC oscillator and PLL characteristics are temperature-dependent and are grouped in two tables.
13.3.4.1 Devices with “6” order code suffix (tested for T
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 V
2. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 24
3. Data based on characterization results, not tested in production
4. Averaged over a 4ms period. After the LOCKED bit is set, a period of t
5. After the LOCKED bit is set ACC
6. Guaranteed by design.
