Pinout

Pin	Name	Type	Function
1	RA2/AN2	bidirectional	PORTA bit 2. Bidirectional digital I/O (TTL input, CMOS output) muxed with ADC analog channel 2 input (AN2).
2	RA3/AN3/VREF	bidirectional	PORTA bit 3. Bidirectional digital I/O (TTL input, CMOS output), analog channel 3 input (AN3), or external A/D reference voltage input (VREF).
3	RA4/T0CKI	bidirectional	PORTA bit 4. Bidirectional digital I/O with Schmitt Trigger input and open-drain output. Also serves as Timer0 external clock input (T0CKI).
4	MCLR/VPP	input	Active-low Master Clear (Reset) input with Schmitt Trigger levels; also serves as the high-voltage programming supply input (VPP) during ICSP programming.
5	VSS	power_in	Ground reference (0 V) for logic and I/O pins.
6	RB0/INT/ECCPAS2	bidirectional	PORTB bit 0. Bidirectional digital I/O with programmable weak pull-up. Alternate functions: external interrupt input (INT) and active-low ECCP auto-shutdown input (ECCPAS2).
7	RB1/T1OSO/T1CKI	bidirectional	PORTB bit 1. Bidirectional digital I/O with programmable weak pull-up. Also Timer1 oscillator output (T1OSO, crystal drive) and Timer1 external clock input (T1CKI, Schmitt Trigger).
8	RB2/T1OSI	bidirectional	PORTB bit 2. Bidirectional digital I/O with programmable weak pull-up. Also Timer1 oscillator crystal input (T1OSI).
9	RB3/CCP1/P1A	bidirectional	PORTB bit 3. Bidirectional digital I/O with programmable weak pull-up. Also Enhanced CCP1 capture input / compare output / PWM output (CCP1) and PWM output A (P1A).
10	RB4/ECCPAS0	bidirectional	PORTB bit 4. Bidirectional digital I/O with programmable weak pull-up and interrupt-on-change. Also active-low ECCP auto-shutdown input (ECCPAS0).
11	RB5/P1B	bidirectional	PORTB bit 5. Bidirectional digital I/O with programmable weak pull-up and interrupt-on-change. Also Enhanced PWM output B (P1B).
12	RB6/P1C	bidirectional	PORTB bit 6. Bidirectional digital I/O with programmable weak pull-up and interrupt-on-change. Also Enhanced PWM output C (P1C). Serves as ICSP clock input (ICSPCLK) with Schmitt Trigger levels during programming.
13	RB7/P1D	bidirectional	PORTB bit 7. Bidirectional digital I/O with programmable weak pull-up and interrupt-on-change. Also Enhanced PWM output D (P1D). Serves as ICSP data (ICSPDAT) with Schmitt Trigger levels during programming.
14	VDD	power_in	Positive supply for logic and I/O pins. Operating range 2.0 V to 5.5 V (Industrial); 3.0 V to 5.5 V (Extended).
15	OSC2/CLKOUT	output	Oscillator crystal output (OSC2, connects to crystal or resonator in Crystal Oscillator mode). In RC mode, outputs CLKOUT at 1/4 the OSC1 frequency, denoting the instruction cycle rate.
16	OSC1/CLKIN	input	Oscillator crystal input (OSC1), external clock source input (CLKIN, CMOS levels), or RC oscillator input (Schmitt Trigger).
17	RA0/AN0	bidirectional	PORTA bit 0. Bidirectional digital I/O (TTL input, CMOS output) muxed with ADC analog channel 0 input (AN0).
18	RA1/AN1	bidirectional	PORTA bit 1. Bidirectional digital I/O (TTL input, CMOS output) muxed with ADC analog channel 1 input (AN1).
