1. The typical values are given for V
2. Based on characterization, not tested in production, unless otherwise specified.
3. Based on characterization done with a 32.768 kHz crystal (MC306-G-06Q-32.768, manufacturer JFVNY) with two 6.8pF
loading capacitors.
4. Tested in production.
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 V
•
all peripherals are disabled unless otherwise mentioned
•
the given value is calculated by measuring the current consumption
