Microchip, 8 bit PIC, PIC12F509 Microcontroller, 4 MHz, 1.5kB FLASH, 8-Pin SOIC

Microchip’s PIC12 Microcontrollers (MCUs) were the world’s first 8-Pin microcontrollers. Originally launched as One Time Programmable (OTP) parts, this range of devices continues to expand as extra features and further improvements are added.

The PIC12F508/509 family of microcontrollers is based upon Microchip’s baseline core with a 2 level hardware stack and 33 instructions. These MCUs provide up to 1 MIPS, up to 1.5 Kbytes program memory with data memory of up to 41 bytes SRAM. On board is a RC oscillator with ±1% accuracy.

33 Instructions

4 MHz Internal Oscillator
6 I/O Pins
One 8-bit Timer
Watchdog Timer (WDT)
In-Circuit Serial Programming (ICSP)
In-Circuit Debugging (ICD)

Microchip’s PIC12F Microcontrollers (MCUs) were the world’s first 8-Pin microcontrollers. Originally launched as One Time Programmable (OTP) parts, this range of devices continues to expand as Microchip adds extra features, further improves specifications and continues to offer ever greater value. Key to the success of the PIC12F was the internal RC oscillator that allowed six I/O channels in an 8-pin package. Later versions of this RC oscillator are configurable between 31kHz and 32MHz.
