PIC16C54-10/P 8-Bit CMOS Microcontroller DIP-18 (PIC16C54-10/P DIP IC)
The PIC16C54-10/P is a low-cost, high-performance 8-bit fully static CMOS microcontroller. It belongs to the baseline family of PIC microcontrollers and utilizes a RISC architecture with only 33 single-word instructions. This specific variant supports a clock speed of up to 10MHz and includes 512 words of OTP (One-Time Programmable) EPROM program memory and 25 bytes of RAM. It is designed for high-speed applications where a small footprint and low power consumption are required, offering a balance between simplicity and execution speed.
This IC is primarily used in high-speed digital logic replacement, automotive control subsystems, and low-power remote transmitters. It is a classic component for electronics projects in India for building standalone high-speed timers, custom communication protocol converters, and learning the fundamentals of RISC-based assembly programming on a stable 18-pin DIP platform.
