1. Guaranteed by characterization results, unless otherwise specified.

2. Guaranteed by test in production.

3. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8pF

loading capacitors.

On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in the following table. The MCU

is placed under the following conditions:

• all I/O pins are in input mode with a static value at VDD or VSS (no load)

• all peripherals are disabled unless otherwise mentioned

• the given value is calculated by measuring the current consumption

– with all peripherals clocked off

– with only one peripheral clocked on
