This section provides an overview of the PIC32MX1XX/2XX 28/36/44-pin Family electrical characteristics for devices that operate at 40 MHz. Refer to Section 31.0 "50 MHz Electrical Characteristics" for additional specifications for operations at higher frequency. Additional information will be provided in future revisions of this document as it becomes available.

Absolute maximum ratings for the PIC32MX1XX/2XX 28/36/44-pin Family devices 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.

(See Note 1)

• Voltage on any 5V tolerant pin with respect to VSS when VDD  2.3V (Note 3) -0.3V to +5.5V
• Voltage on any 5V tolerant pin with respect to VSS when VDD < 2.3V (Note 3) -0.3V to +3.6V
• Voltage on D+ or D- pin with respect to VUSB3V3 -0.3V to (VUSB3V3 + 0.3V)
• Voltage on VBUS with respect to VSS -0.3V to +5.5V

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 Table 30-2).

3: See the "Pin Diagrams" section for the 5V tolerant pins.
