6 Power Supplies

The PIC32CM JH00/JH01 has the following power supply pins:

Table 6-1. Power Supply Pins
Name	Associated Ground	Description	Voltage Range ⁽³⁾	Decoupling Capacitors ⁽³⁾
VDDIN = VDD ⁽¹⁾	GND	Powers I/O lines, OSC48M and internal regulator	REG_37	REG_7, REG_8
AVDD = VDD ⁽¹⁾	AVSS	Powers I/O lines, ADC, AC, DAC, PTC, OSCULP32K, OSC32K, and XOSC32K	REG_37	REG_17, REG_19
VDDIO ⁽²⁾	GND	Powers I/O lines and XOSC	REG_37	REG_4, REG_5
VDDCORE	GND	Internal regulated voltage output. Powers the core, memories, peripherals, and FDPLL96M. Note: VDDCORE is not an input for an external power supply.	REG_36	REG_1, REG_3
Note: The same voltage must be applied to both the VDDIN and AVDD pins. This common voltage is referred to as VDD in the data sheet. VDDIO must always be less than or equal to VDDIN = AVDD = VDD. REG_X values: refer to Power Supply Electrical Specifications from the Electrical Characteristics chapter.

The PIC32CM JH00/JH01 voltage regulator offers two modes:

Normal mode: This is the default mode in active and idle modes.
Low-Power (LP) mode: The regulator can switch to this mode during Standby mode, depending on the STDBYCFG.VREGSMOD and the presence of sleepwalking peripherals. Refer to Table 19-4: Regulator State in Sleep Mode for additional information.
