PIC16F505 Microcontroller

PIC16F505 Microcontroller 

The PIC16F505 is an 8-bit Flash microcontroller developed by Microchip Technology. It belongs to the baseline PIC family and is designed for very low-cost and low-power embedded control applications.

It uses Harvard architecture with a RISC instruction set. Compared to mid-range PIC16 devices, it has a simpler architecture, making it suitable for basic control tasks such as switching, timing, and simple logic control. The device operates at clock frequencies up to 20 MHz and is ideal for small embedded systems.
