PIC12F1572-I

Microchip · Microcontrollers (MCU/MPU/SOC) · SOIC-8

PIC12F1572-I from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply voltage. Operating range 2.3V to 5.5V (PIC12F1572) or 1.8V to 3.6V (PIC12LF1572). Bypass with 0.1 uF ceramic close to the pin.
2 RA5 bidirectional General purpose I/O with individually selectable weak pull-up and interrupt-on-change. Alternate functions: T1CKI (Timer1 clock input), PWM1 output (alt), EUSART RX/DT (alt), CWG1A output (alt), CLKIN (external oscillator input).
3 RA4 bidirectional General purpose I/O with weak pull-up and IOC. Alternate functions: AN3 (ADC ch3), C1IN1- (comparator input), T1G (Timer1 gate), PWM2 (alt), EUSART TX/CK (alt), CWG1B (alt), CLKOUT.
4 RA3/MCLR/VPP input Input-only pin. Master Clear (active-low reset) when MCLRE is enabled, or general-purpose input RA3 with weak pull-up and IOC when MCLR is disabled. Also serves as programming high-voltage entry pin (VPP) during ICSP. Optional T1G alternate.
5 RA2 bidirectional General purpose I/O with weak pull-up, interrupt-on-change, and external interrupt (INT). Alternate functions: AN2 (ADC ch2), C1OUT (comparator output), T0CKI (Timer0 clock), PWM3, CWG1FLT (fault input), CWG1A (default).
6 RA1/ICSPCLK bidirectional General purpose I/O with weak pull-up and IOC. Alternate functions: AN1 (ADC ch1), VREF+ (external ADC/DAC reference input), C1IN0- (comparator input), PWM1 (default), EUSART RX/DT (default), ICSPCLK/ICDCLK (in-circuit serial programming clock).
7 RA0/ICSPDAT bidirectional General purpose I/O with weak pull-up and IOC. Alternate functions: AN0 (ADC ch0), DAC1OUT (5-bit DAC output), C1IN+ (comparator +input), PWM2 (default), EUSART TX/CK (default), CWG1B (default), ICSPDAT/ICDDAT (ICSP data).
8 VSS power_in Ground/negative supply reference (0 V). Common return for VDD.

Two STEP files. Same geometry, different body top:

File Size Use it when
pic12f1572-i.step 122 KB You want the bare part, or you mark your own boards.
pic12f1572-i-etched.step 1.9 MB You want the part with PIC12F1572-I already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 498 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
