2 RC5 bidirectional General purpose I/O with individually controlled direction and high-current source/sink capability.
3 RC4/C2OUT bidirectional General purpose I/O with individually controlled direction; also comparator 2 output C2OUT.
4 RC3/AN7/OP1 bidirectional General purpose I/O with individually controlled direction; also ADC channel AN7 and op amp 1 output OP1.
5 RC6/OP1- bidirectional General purpose I/O with individually controlled direction; also op amp 1 inverting input OP1-.
6 RC7/OP1+ bidirectional General purpose I/O with individually controlled direction; also op amp 1 non-inverting input OP1+.
7 RB7 bidirectional General purpose I/O with individually controlled direction.
8 RB6 bidirectional General purpose I/O with individually controlled direction.
9 RB5/OP2+ bidirectional General purpose I/O with individually controlled direction; also op amp 2 non-inverting input OP2+.

11 RC2/AN6/OP2 bidirectional General purpose I/O with individually controlled direction; also ADC channel AN6 and op amp 2 output OP2.
12 RC1/AN5/C2IN- bidirectional General purpose I/O with individually controlled direction; also ADC channel AN5 and comparator 2 inverting input C2IN-.
13 RC0/AN4/C2IN+ bidirectional General purpose I/O with individually controlled direction; also ADC channel AN4 and comparator 2 non-inverting input C2IN+.
14 RA2/AN2/C1OUT/T0CKI bidirectional General purpose I/O with individually controlled direction; also ADC channel AN2, comparator 1 output C1OUT and TMR0 clock input T0CKI.
15 RA1/AN1/C1IN-/CVREF/ICSPCLK bidirectional General purpose I/O with individually controlled direction; also ADC channel AN1, comparator 1 inverting input, comparator reference CVREF and ICSP clock ICSPCLK.
16 RA0/AN0/C1IN+/ICSPDAT bidirectional General purpose I/O with individually controlled direction; also ADC channel AN0, comparator 1 non-inverting input C1IN+ and ICSP data ICSPDAT.
17 VSS power_in Ground reference for the device.
18 VDD power_in Positive supply; the device operates from 2.0V to 5.5V over the industrial and extended ranges.
19 RA5/OSC1/CLKIN bidirectional General purpose I/O with individually controlled direction; also oscillator input OSC1 and clock input CLKIN.
20 RA4/AN3/OSC2/CLKOUT bidirectional General purpose I/O with individually controlled direction; also ADC channel AN3, oscillator output OSC2 and clock output CLKOUT.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
