Microchip Tech · MICROCHIP · DIP-28-600mil

PIC16C57C-04I from Microchip Tech, in a DIP-28-600mil. 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 T0CKI input Schmitt Trigger clock input to Timer0; must be tied to VSS or VDD if not in use to reduce current consumption.
2 VDD power_in Positive supply for logic and I/O pins.
3 N/C unconnected Unused, do not connect.
4 VSS power_in Ground reference for logic and I/O pins.
5 N/C unconnected Unused, do not connect.
6 RA0 bidirectional PORTA bit 0, bi-directional I/O port pin with TTL input buffer.
7 RA1 bidirectional PORTA bit 1, bi-directional I/O port pin with TTL input buffer.
8 RA2 bidirectional PORTA bit 2, bi-directional I/O port pin with TTL input buffer.
9 RA3 bidirectional PORTA bit 3, bi-directional I/O port pin with TTL input buffer.
10 RB0 bidirectional PORTB bit 0, bi-directional I/O port pin with TTL input buffer.
11 RB1 bidirectional PORTB bit 1, bi-directional I/O port pin with TTL input buffer.
12 RB2 bidirectional PORTB bit 2, bi-directional I/O port pin with TTL input buffer.
13 RB3 bidirectional PORTB bit 3, bi-directional I/O port pin with TTL input buffer.
14 RB4 bidirectional PORTB bit 4, bi-directional I/O port pin with TTL input buffer.
15 RB5 bidirectional PORTB bit 5, bi-directional I/O port pin with TTL input buffer.
16 RB6 bidirectional PORTB bit 6, bi-directional I/O port pin with TTL input buffer.
17 RB7 bidirectional PORTB bit 7, bi-directional I/O port pin with TTL input buffer.
18 RC0 bidirectional PORTC bit 0, bi-directional I/O port pin with TTL input buffer.
19 RC1 bidirectional PORTC bit 1, bi-directional I/O port pin with TTL input buffer.
20 RC2 bidirectional PORTC bit 2, bi-directional I/O port pin with TTL input buffer.
21 RC3 bidirectional PORTC bit 3, bi-directional I/O port pin with TTL input buffer.
22 RC4 bidirectional PORTC bit 4, bi-directional I/O port pin with TTL input buffer.
23 RC5 bidirectional PORTC bit 5, bi-directional I/O port pin with TTL input buffer.
24 RC6 bidirectional PORTC bit 6, bi-directional I/O port pin with TTL input buffer.
25 RC7 bidirectional PORTC bit 7, bi-directional I/O port pin with TTL input buffer.
26 OSC2/CLKOUT output Oscillator crystal output connecting to crystal or resonator in crystal mode; in RC mode it outputs CLKOUT at 1/4 the frequency of OSC1, denoting the instruction cycle rate.
27 OSC1/CLKIN input Schmitt Trigger oscillator crystal input / external clock source input.
28 MCLR input Schmitt Trigger master clear input; active low RESET to the device.

CAD (KiCad official)

  • Symbol: PIC16C57C-04I
  • Footprint: Package_DIP:DIP-28_W7.62mm
  • 3D model: DIP-28-600mil (KiCad packages3D, STEP)
  • 3D model files: pic16c57c-04i-etched.step / pic16c57c-04i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pic16c57c-04i.step / pic16c57c-04i.glb are the bare package body.
