PIC12 Overview

Microchip's PIC12 is a RISC based architecture family, with 33 single-word/ single-cycle instructions. The PIC12 is high-performance, low-cost, 8-bit fully-static

Flash based microcontrollers. PIC12 employs 12-bit instruction word. All instructions are single cycle (200 μs) except for program branches, which take two cycles.

PIC12 family of microchip includes following devices: PIC12F508, PIC12F509, PIC12F510, PIC12F519, PIC12F609, PIC12F615, PIC12F629, PIC12F635, PIC12F675, and PIC12F883. The future variants of PIC12 family are: PIC12F1822, and PIC12F617.

The PIC10 family equipped with special feature that reduce the design complexity, power consumption and system cost. The requirement external reset circuitry eliminated because of internal POR(Power on Reset) and Device Reset Timer. Likewise INTRC Internal Oscillator mode, Sleep mode, Watchdog Timer, and code protection improves the system cost, power & reliability.
