MICROCHIP PIC16C73B 8-bit CMOS Microcontroller, 20MHz

The MICROCHIP PIC16C73B-20/SP is a member of the PIC16 family of 8-bit microcontrollers, offering a powerful RISC architecture with 200 nanosecond instruction execution. It balances high performance with ease of programming, featuring only 35 single-word instructions and a One Time Programmable (OTP) CMOS design. This device is an excellent choice for embedded control applications, delivering the advantages of the well-recognised mid-range x14 architecture.

It offers a substantial 7kB of addressable program memory and 192 bytes of data memory (RAM), providing ample space for complex code and variables. With 22 general-purpose I/O pins and a 5-channel, 8-bit analog-to-digital (A/D) converter, it is highly versatile for interfacing with sensors, actuators, and other peripheral components. The microcontroller operates across a wide voltage range from 2.5V to 5.5V and at a maximum frequency of 20MHz.
