PIC16F818 Microcontroller

PIC16F818 Microcontroller 

The PIC16F818 is an 8-bit Flash microcontroller developed by Microchip Technology, part of the PIC16F family. It is designed for low-power, cost-effective embedded applications, particularly those needing analog functionality alongside digital control.

It uses Harvard architecture with a RISC instruction set, allowing most instructions to execute in a single clock cycle. The device operates at up to 20 MHz, has Flash program memory for easy reprogramming, and integrates analog peripherals like ADC and comparators, making it suitable for sensor-based applications.
