PIC16F1503-I

Microchip Tech · Microcontrollers (MCU/MPU/SOC) · SOIC-14

PIC16F1503-I from Microchip Tech, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

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.
