1. V_DD = 3.3 V ± 10% / 5.0 V ± 10%, T_A = −40 to 125 °C, unless otherwise specified.
2. All values need to be confirmed during device validation.
3. This does not include consumption linked to clock tree toggling and peripherals consumption when RC oscillator is ON.

Slow internal RC oscillator (128 kHz) electrical
characteristics
The device provides a 128 kHz low power internal RC oscillator. This can be used as the
reference clock for the RTC module.
