PIC12F629 8-bit PIC Microcontroller

PIC12F629 is an eight-pin 8-bit PIC Microcontroller with an operating voltage from 2V to 5.5V. It has 128 bytes of EEPROM with 4 internal oscillator configuration up to 4MHz (RC oscillator) with power-on-reset. It also has two timers (8bit and 16-bit) and one comparator.

This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS Flash-based 8-bit microcontroller comes with Microchip’s powerful PIC MCU architecture into an 8-pin package and features 1 channel comparator and 128 bytes of EEPROM data memory. This device is easily adapted for automotive, industrial, appliances and consumer entry-level product applications that require field re-programmability.

Programming PIC Microcontroller

To program the PIC microcontroller you will need an IDE (Integrated Development Environment, a compiler, and an IPE (Integrated Programming Environment).

IDE: MPLABX v3.35

IPE: MPLAB IPE v3.35

Compiler: XC8

Microchip has given all these three software for free. They can be downloaded directly from their official page.
