2 All values need to be confirmed during device validation.
3 Stated values take into account only analog module consumption but not the digital contributor (clock tree and
enabled peripherals).
4.13 Slow external crystal oscillator (32 kHz) electrical characteristics
The device provides a low power oscillator/resonator driver.
