This document is a preliminary datasheet for the PIC12F508/509/16F505 series 8/14-pin, 8-bit Flash microcontrollers, released by Microchip Technology Inc. in 2007. The datasheet describes the features and characteristics of these products.
The PIC12F508, PIC12F509 and PIC16F505 are low‑cost, high‑performance 8‑bit flash microcontrollers from Microchip. They use a RISC core with 33 single‑word instructions, a 12‑bit wide instruction set, and offer a range of on‑chip peripherals such as timers, watchdog, and real‑time clock.
The devices are supplied in multiple package styles (8‑pin PDIP, SOIC, 14‑pin PDIP, MSOP, DFN, TSSOP) and support a variety of oscillator options, making them suitable for applications from personal‑care appliances to low‑power remote transmitters. Detailed ordering information and worldwide sales contacts are provided at the end of the document.
