8.9 Voltage Supply Domains

The CC1311R3 device can interface to two or three different voltage domains depending on the package type. On-chip level converters ensure correct operation as long as the signal voltage on each input/output pin is set with respect to the corresponding supply pin (VDDS, VDDS2, or VDDS3). Pin Function to VDDS Mapping Table lists the pin-to-VDDS mapping.
