Microchip PIC16F818 8-Bit Flash Microcontroller, 20MHz, DIP18

The Microchip PIC16F818-I/P is a high-performance, 8-bit CMOS flash microcontroller from the baseline PIC16 family, combining powerful RISC architecture with ease of programming. It executes instructions in just 200 nanoseconds, delivering efficient processing for a wide range of embedded control applications. This device is built around a 12-bit program word and integrates a robust set of features, including 1.75kB of program memory and 128 bytes of data memory (EEPROM).

It offers 16 general-purpose I/O pins for flexible interfacing and includes a 5-channel, 10-bit Analogue-to-Digital Converter (ADC) for precise sensor reading. The microcontroller operates at a maximum frequency of 20MHz across a wide voltage range of 2.0V to 5.5V, making it suitable for both low-power and standard voltage designs. Its compact DIP18 through-hole package provides a convenient form factor for prototyping and production.
