13.3.5 Internal RC oscillator
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
13.3.5.1 Internal RC oscillator calibrated at 5.0V
The ST7 internal clock can be supplied by an internal RC oscillator (selectable by option byte).
Notes:
1. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 22
2. Tested in production at 5.0 V only
13.3.5.2 Internal RC oscillator calibrated at 3.3V
The ST7 internal clock can be supplied by an internal RC oscillator (selectable by option byte).
Notes:
1. See “INTERNAL RC OSCILLATOR ADJUSTMENT” on page 22
2. Tested in production at 3.3 V only
