Microchip PIC16F54-I/SO 8-bit Microcontroller Overview

The Microchip PIC16F54-I/SO is a high-performance, cost-effective 8-bit microcontroller built on Microchip’s robust PIC® architecture. Housed in an 18-pin SOIC (Small Outline Integrated Circuit) package, this device is designed for a wide range of embedded control applications, from consumer electronics and automotive systems to industrial automation and low-power devices.

At its core, the PIC16F54 features a RISC-based CPU with a 12-bit wide instruction set, enabling simple yet efficient code execution. With an operating frequency of up to 20 MHz, it delivers a solid balance of processing power and energy consumption. The microcontroller includes 512 x 12 words of ROM program memory and 25 bytes of RAM data memory, providing sufficient resources for many small-scale control tasks.

A key strength of this MCU lies in its versatile I/O capabilities. It offers 12 I/O pins, all of which are programmable and feature individual direction control. These pins can interface directly with external components such as sensors, LEDs, buttons, and relays, making it an ideal solution for direct user interaction and peripheral control.

The PIC16F54-I/SO is engineered for low-power operation, supporting a wide voltage range from 2.0V to 5.5V. This makes it suitable for battery-powered and portable applications where power efficiency is critical. Furthermore, it includes an integrated timer module and an on-chip watchdog timer (WDT) for enhanced system reliability, helping to recover from unexpected software stalls.

Its SOIC package (I/SO) is designed for surface-mount technology (SMT), facilitating automated assembly processes and making it well-suited for high-volume manufacturing. The industrial temperature range (-40°C to +85°C) ensures stable performance even in harsh environmental conditions.

ICGOODFIND: The PIC16F54-I/SO stands out as a reliable, foundational 8-bit microcontroller from Microchip. Its combination of a simple architecture, essential peripherals, low power consumption, and a compact form factor offers an excellent entry point for designers developing cost-sensitive, space-constrained embedded systems.
