This section provides an overview of PIC32MX3XX/4XX electrical characteristics. Additional information will be provided
in future revisions of this document as it becomes available. 

Absolute maximum ratings for the PIC32MX3XX/4XX are listed below. Exposure to these maximum rating conditions
for extended periods may affect device reliability. Functional operation of the device at these or any other conditions
above the parameters indicated in the operation listings of this specification is not implied.

Note 1: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions
above those indicated in the operation listings of this specification is not implied. Exposure to maximum
rating conditions for extended periods may affect device reliability.

2: Maximum allowable current is a function of device maximum power dissipation (see 

3: See the “

” section for the 5V tolerant pins.
