Pinout

Pin Name Type Function
1 MCLR/RE3 input Master Clear input (or programming voltage input) is an active-low Reset to the device; RE3 is a general-purpose input-only pin available only when the MCLRE Configuration bit is cleared.
2 RA0/CVREF/AN0/ULPWU bidirectional General-purpose I/O pin that can also output the comparator reference voltage CVREF, serve as A/D Analog Input 0, or serve as the Ultra Low-Power Wake-up input.
3 RA1/AN1 bidirectional Digital I/O pin that can also function as A/D Analog Input 1.
4 RA2/VREF-/AN2 bidirectional Digital I/O pin that can also function as the A/D reference voltage (low) input or as A/D Analog Input 2.
5 RA3/VREF+/AN3 bidirectional Digital I/O pin that can also function as the A/D reference voltage (high) input or as A/D Analog Input 3.
6 VDDCORE/VCAP power_out External filter capacitor connection for the on-chip voltage regulator; a 10 µF capacitor to ground is required when the regulator is enabled, and the pin must not be connected to VDD.
7 RA5/AN4/HLVDIN/T1CKI/SS bidirectional Digital I/O pin that can also function as A/D Analog Input 4, High/Low-Voltage Detect input, Timer1 clock input, or SPI slave select input.
8 VSS power_in Ground reference for logic and I/O pins.
9 OSC1/CLKIN/RA7 bidirectional Oscillator crystal input (OSC1) or external clock source input (CLKIN); can serve as general-purpose I/O RA7 only in oscillator modes where the oscillator pins are not used.
10 OSC2/CLKOUT/RA6 bidirectional Oscillator crystal output (OSC2) connecting to a crystal or resonator, or CLKOUT which outputs FOSC/4 in certain oscillator modes; can serve as general-purpose I/O RA6 in oscillator modes where the oscillator pins are not used.
11 RC0/SOSCO/SCLKI bidirectional Digital I/O pin that can also function as the Timer1 oscillator output (SOSCO) or the digital SOSC clock input (SCLKI).
12 RC1/SOSCI bidirectional Digital I/O pin that can also function as the SOSC oscillator input (SOSCI).
13 RC2/T1G/CCP2 bidirectional Digital I/O pin that can also function as the Timer1 external clock gate input (T1G) or CCP2 capture input / compare and PWM output.
14 RC3/REFO/SCL/SCK bidirectional Digital I/O pin that can also function as the reference clock output (REFO), the MSSP I2C clock (SCL), or the MSSP SPI clock (SCK).
15 RC4/SDA/SDI bidirectional Digital I/O pin that can also function as the MSSP I2C data (SDA) or SPI data input (SDI).
16 RC5/SDO bidirectional Digital I/O pin that can also function as the MSSP SPI data output (SDO).
17 RC6/CANTX/TX1/CK1/CCP3 bidirectional Digital I/O pin that can also function as CAN bus TX, EUSART1 asynchronous transmit or synchronous clock, or CCP3 capture/compare/PWM.
18 RC7/CANRX/RX1/DT1/CCP4 bidirectional Digital I/O pin that can also function as CAN bus RX, EUSART1 asynchronous receive, EUSART1 synchronous data, or CCP4 capture/compare/PWM.
19 VSS power_in Ground reference for logic and I/O pins.
20 VDD power_in Positive supply for logic and I/O pins.
21 RB0/AN10/C1INA/FLT0/INT0 bidirectional Digital I/O pin with weak pull-up (enabled by clearing RBPU) that can also function as A/D Analog Input 10, Comparator 1 input A, ECCP Fault input FLT0, or External Interrupt 0.
22 RB1/AN8/C1INB/P1B/CTDIN/INT1 bidirectional Digital I/O pin with weak pull-up that can also function as A/D Analog Input 8, Comparator 1 input B, ECCP1 PWM output B, CTMU pulse delay input, or External Interrupt 1.
23 RB2/CANTX/C1OUT/P1C/CTED1/INT2 bidirectional Digital I/O pin with weak pull-up that can also function as CAN bus TX, Comparator 1 output, ECCP1 PWM output C, CTMU Edge 1 input, or External Interrupt 2.
24 RB3/CANRX/C2OUT/P1D/CTED2/INT3 bidirectional Digital I/O pin with weak pull-up that can also function as CAN bus RX, Comparator 2 output, ECCP1 PWM output D, CTMU Edge 2 input, or External Interrupt 3.
25 RB4/AN9/C2INA/ECCP1/P1A/CTPLS/KBI0 bidirectional Digital I/O pin with weak pull-up that can also function as A/D Analog Input 9, Comparator 2 input A, ECCP1 capture/compare/PWM output A, CTMU pulse generator output, or interrupt-on-change KBI0.
26 RB5/T0CKI/T3CKI/CCP5/KBI1 bidirectional Digital I/O pin with weak pull-up that can also function as Timer0 external clock input, Timer3 external clock input, CCP5 capture/compare/PWM, or interrupt-on-change KBI1.
27 RB6/PGC/TX2/CK2/KBI2 bidirectional Digital I/O pin with weak pull-up that can also function as the in-circuit debugger and ICSP programming clock (PGC), EUSART2 asynchronous transmit or synchronous clock, or interrupt-on-change KBI2.
28 RB7/PGD/T3G/RX2/DT2/KBI3 bidirectional Digital I/O pin with weak pull-up that can also function as the in-circuit debugger and ICSP programming data (PGD), Timer3 gate input, EUSART2 asynchronous receive or synchronous data, or interrupt-on-change KBI3.
