Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive supply; the PIC16F1503 operating range is 2.3V to 5.5V (PIC16LF1503 is 1.8V to 3.6V). |
| 2 | RA5 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include CLKIN external clock input (EC mode), T1CKI, NCO1CLK and CLC1IN1. |
| 3 | RA4 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN3, T1G, CLKOUT (FOSC/4), and NCO1 or SDO selected via APFCON. |
| 4 | RA3 | input | Input-only general purpose pin (its TRIS bit always reads '1'); when MCLRE is set it is the Master Clear input with internal weak pull-up, and it also serves as the VPP programming voltage input. |
| 5 | RC5 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include PWM1, CLC1 output and CWG1A primary CWG output. |
| 6 | RC4 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include C2OUT comparator 2 output, CLC2IN1 input and CWG1B complementary CWG output. |
| 7 | RC3 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN7, comparator C1/C2 negative inputs, PWM2, CLC2IN0 input and SPI SS. |
| 8 | RC2 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN6, comparator C1/C2 negative inputs, and SPI SDO when selected via APFCON. |
| 9 | RC1 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN5, comparator C1/C2 negative inputs, PWM4, NCO1 output, and I2C SDA or SPI SDI. |
| 10 | RC0 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN4, comparator C2 positive input, CLC2 output, and I2C SCL or SPI SCK. |
| 11 | RA2 | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN2, DACOUT2, C1OUT, T0CKI, external interrupt INT, PWM3, CLC1 output and CWG1FLT fault input. |
| 12 | RA1/ICSPCLK | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN1, VREF+ A/D positive reference, comparator inputs C1IN0-/C2IN0-, and ICSP serial programming clock (ICSPCLK). |
| 13 | RA0/ICSPDAT | bidirectional | General purpose I/O with 25 mA sink/source capability; alternate functions include AN0, DACOUT1, comparator C1IN+ input, and ICSP serial programming data (ICSPDAT). |
| 14 | VSS | power_in | Ground reference for the device. |
