PIC12F1822/1840 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 PIC12F1822/1840 family of microcontrollers is based upon Microchip’s enhanced mid-range core that features a deep hardware stack and 49 instructions. These MCUs provide up to 8 MIPS, 3.5 Kbytes program memory and data memory of 128 bytes. On board is a configurable RC oscillator with ±1% accuracy.

Microchip PIC12F 8-bit PIC® Microcontrollers


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.
