4.6 PIC32MZ DA Power Requirements
Devices in the PIC32MZ DA family are quadruple voltage supply designs. Two of the voltage supplies are identical to the PIC32MZ EC and PIC32MZ EF voltage supplies. The third voltage supply is for the DDR memory interface, and requires a 1.8 volt supply. The fourth voltage supply is for the VBAT pin, but it can be connected to the VDD power supply. See Figure 4-5.
Refer to the AC/DC Characteristics and Timing Requirements and the “Electrical Characteristics” chapter in the specific device data sheet for the power requirements of the device.
