23.2 Module Overview

A typical MVIO on an 8-bit PIC® microcontroller has an operating voltage range of 1.62V-5.5V. However, the MVIO on this device is customized with additional features to support limited operation in the 0.95V-1.62V range as well for low-voltage I3C and I2C data transfers.

Table 23-1. Operating Voltage Range for MVIO Domains
Power Domain Voltage Range Additional Notes
VDD Power Domain 1.8V – 5.5V Device operating range
VDDIOx Power Domain 1.62V – 5.5V(1) Standard operating range MVIO pads are fully functional
0.95V – 1.62V(2) Low-voltage operating range MVIO pads are held in reset with limited I3C/I2C functionality
Note:
  1. The maximum voltage for VDDIOx power domain is 3.63V when I3C is enabled.
  2. When the I3C low-voltage buffers are used within the 1.4V-1.62V range of VDDIOx power domain, a minimum device VDD of 2.4V is required for proper operation.
  3. The VDDIOx supply voltage can go below the device’s minimum VDD of 1.8V. However, the VDD must be within the specified operating range for the device to be functional.
