PIC12F508/509 8-Bit Flash Microcontrollers 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. Features 33 Instructions
