† NOTICE: 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.

Note 1: Power dissipation is calculated as follows:
Note 2: Voltage spikes below V
Note 3: PORTD and PORTE not available on the PIC18C2X2 devices.
