PIC16F54-I/SP 8-Bit Flash Microcontroller Baseline Core DIP-18 (PIC16F54-I/SP DIP IC)
The PIC16F54-I/SP is an entry-level, 8-bit Flash-based microcontroller belonging to Microchip’s "Baseline" family. Housed in an 18-pin Skinny DIP package, it is designed for simple, high-volume applications where low cost and small code footprints are the primary requirements. It features a simplified RISC architecture with only 33 single-word instructions. This IC includes 768 bytes of Flash program memory and 25 bytes of RAM. While it lacks some of the integrated analog peripherals found in the mid-range series, its high speed, low power consumption, and wide operating voltage make it a reliable and robust choice for basic logic replacement and timing tasks.
This IC is primarily used in consumer appliances, electronic toys, and basic lighting controllers. It is a common component for Arduino electronics projects in India for building DIY logic gates, simple LED flasher circuits, and educational projects where students learn the fundamentals of RISC assembly and low-level hardware control in a standard 18-pin DIP footprint.
