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 |
| VSW | - | Switching Regulator Mode (BUCK) Output | - |
Note: REG_X values: refer to 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 AVDD analog cluster must be confined as inputs
only.
Refer to the I/O PINMUX tables from Pinout and Packaging chapter for the list 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.
