1. Typical values not tested in production. Since the peripherals are powered by an internally regulated, constant digital

supply voltage, the values are similar in the full supply voltage range.

2. Data based on a differential IDD measurement between no peripheral clocked and a single active peripheral. This

measurement does not include the pad toggling consumption.

3. Data based on a differential IDD measurement between reset configuration (CAN disabled) and a permanent CAN data

transmit sequence in loopback mode at 1 MHz. This measurement does not include the pad toggling consumption.

4. Data based on a differential IDD measurement between reset configuration and continuous A/D conversions.
