Microchip Tech · Microcontroller Units (MCUs/MPUs/SOCs) · SOIC-18-300mil

PIC16F54-I from Microchip Tech, in a SOIC-18-300mil. 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 RA2 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
2 RA3 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
3 T0CKI input Clock input to Timer0; must be tied to VSS or VDD if not in use to reduce current consumption.
4 MCLR/VPP input Active-low Reset to device; voltage on the MCLR/VPP pin must not exceed VDD to avoid unintended entering of Programming mode.
5 VSS power_in Ground reference for logic and I/O pins.
6 RB0 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
7 RB1 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
8 RB2 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
9 RB3 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
10 RB4 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
11 RB5 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
12 RB6/ICSPCLK bidirectional Bidirectional I/O pin; serves as the programming clock (ICSPCLK, Schmitt Trigger input) in Program/Verify mode.
13 RB7/ICSPDAT bidirectional Bidirectional I/O pin; serves as the serial programming data (ICSPDAT) I/O in Program/Verify mode.
14 VDD power_in Positive supply for logic and I/O pins.
15 OSC2/CLKOUT passive Crystal oscillator output in XT/HS/LP modes; in RC mode outputs CLKOUT, which has 1/4 the frequency of OSC1.
16 OSC1/CLKIN input Oscillator crystal input, or external clock source input.
17 RA0 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
18 RA1 bidirectional Bidirectional I/O pin with TTL input and CMOS output levels.
