Fast internal RC oscillator (16 MHz) electrical characteristics

The device provides a 16 MHz fast internal RC oscillator. This is used as the default clock at the power-up of the device.

2 All values need to be confirmed during device validation.

3 PLLIN clock retrieved directly from FXOSC clock. Input characteristics are granted when oscillator is used in

functional mode. When bypass mode is used, oscillator input clock should verify fPLLIN and ΔPLLIN.

4 f

CPU 64 MHz can be achieved only at up to 105 °C
