On-Chip Peripherals

Notes:

Data based on a differential IDD measurement between the on-chip peripheral when kept under reset, not

clocked and the on-chip peripheral when clocked and not kept under reset. This measurement does not

include the pad toggling consumption.

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

conversions.
