7.2.1 Power Supplies

The PIC32CM SG00/GC00 has the following power supply pins:

• AVDD powers the Backup power domain as well as the ADC, Analog Comparator (AC), and the Peripheral Touch Controller (PTC)
• VDDREG powers the internal regulators for the VDDCORE_SW, VDDCORE_RAM, and VDDCORE_BU power domains
• VDDIO powers I/O lines, an External Crystal Oscillator (XOSC), the 48 MHz Digital Frequency Locked Loop (DFLL48), and two charge pumps which support the Analog Comparator (AC), 48 MHz Oscillator, and the ADCs on the device (ADC0 and PTC ADC). Most VDDIO pins also power the device's Flash panel through double bonding.

For decoupling recommendations for the different power supplies, refer to the schematic checklist.
