MICROCHIP PIC16C5x 8-Bit OTP Microcontroller, PIC16 Core, 4MHz, DIP-28

The MICROCHIP PIC16C5x 8-Bit OTP Microcontroller is a robust, one-time programmable (OTP) integrated circuit from the established PIC16 family. Designed for embedded control applications, it combines a proven PIC16 core architecture with the flexibility of OTP memory, making it ideal for cost-sensitive, high-volume production runs where firmware is finalised.

Operating at a maximum frequency of 4MHz, this microcontroller delivers reliable performance for a wide range of tasks. It features 896 bytes of OTP program memory and 24 bytes of RAM, providing sufficient space for efficient code execution and data handling in many control scenarios. The device offers 20 versatile I/O pins, facilitating connection to sensors, actuators, and other peripheral components, and includes an RS232 interface for straightforward serial communication.

Housed in a through-hole DIP (Dual In-line Package) with 28 pins, it is perfectly suited for prototyping, educational use, and legacy system maintenance where through-hole mounting is preferred. Its wide operating voltage range from 3V to 5.5V allows for compatibility with various power supplies, including battery-operated systems. The operational temperature range of 0°C to 70°C ensures stable performance in standard commercial environments.
