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. |
