PIC16C505-04/P 8-Bit CMOS Microcontroller DIP-14 (PIC16C505-04/P DIP IC)
The PIC16C505-04/P is a member of the baseline family of 8-bit CMOS microcontrollers from Microchip. It features a high-performance RISC CPU with only 33 single-word instructions and is designed for low-cost, space-sensitive applications. This specific variant operates at a maximum frequency of 4MHz and includes 1024 words of OTP (One-Time Programmable) EPROM program memory and 72 bytes of RAM. It is equipped with an internal 4MHz RC oscillator, which reduces the need for external components, and provides 12 bidirectional I/O pins in a compact 14-pin DIP package.
This IC is primarily used in small appliances, automotive sensors, and low-power remote control systems. It is a reliable component for electronics projects in India for building standalone logic sequencers, dedicated timing circuits, and learning baseline PIC assembly programming on a medium-pin-count platform.
