6 Power Supplies
The PIC32CX SG41/SG60/SG61 has the following power supply pins:
| Name | Associated Ground | Description | Voltage Range (Electrical Characteristics Parameters Number) |
|---|---|---|---|
| VDD | VSS | Digital Supply Voltage | REG_37 |
| AVDD | AVSS | Analog Supply Voltage | REG_39 |
| VBAT (PB03) | - | Battery Supply Voltage which powers the Automatic Power Switch | REG_41 |
| VDDCORE | VSS |
Core Supply Voltage Output (LDO mode) Core Supply Voltage Input (BUCK mode) Note: VDDCORE is not an input for an external power supply.
| REG_36 |
| VDDIOB | VSS |
Powers I/O B lines. Voltage is 1.71V to 3.63V. VDDIOB voltage level must be equal or lower than VDD. Note: Only available on the SG41 devices.
| 1.71V to 3.63V |
| VSW | - | Switching Regulator Mode (BUCK) Output | - |
Note: For REG_X values, refer to the Power Supply
Electrical Specifications from the “Electrical Characteristics”
chapter.
Important: The same voltage must
be applied to VDD and AVDD. Refer to the Power-up and Power-down Considerations in the “Device Start-up” chapter for
additional information.
CAUTION: Any and all I/O, as well
as digital alternate functions on the AVDD analog cluster must be confined as inputs
only.
Refer to the I/O PINMUX tables from the Chapter Pinout and Packaging for a list of per package of pins powered by AVDD.
Note: The IOSET configurations for the concerned digital alternate output functions must also be considered, refer to the IOSET Configurations in the "Pinout and Packaging" chapter.
