This section provides an overview of the PIC32MX1XX/2XX electrical characteristics for devices that operate at 40 MHz. Refer to Section 30.0 '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 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.

Examples of typical application connections are shown

in Figure 2-5 and Figure 2-6.
