Overview

The PIC18F26Q43-I/SP is a high-performance 8-bit microcontroller featuring 64KB of Flash memory and a 64MHz internal oscillator. It is part of the PIC18-Q43 family, which emphasizes Core Independent Peripherals (CIPs) that offload tasks from the CPU for increased efficiency. This specific variant comes in a 28-pin SPDIP package, making it ideal for prototyping on breadboards or through-hole PCB designs.

Why Choose This Part

The 28-pin SPDIP package provides a rare combination of modern peripheral density with easy-to-handle through-hole mounting. Its 64KB of Flash and 4KB of RAM allow for complex firmware implementations, while the 1KB of dedicated EEPROM ensures reliable storage for non-volatile configuration data.

Applications

Hardware Interfacing
Utilize the multiple UART, SPI, and I2C interfaces to coordinate communication between various sensors and actuators.
Real-Time Signal Processing
Leverage the integrated 12-bit ADC with Computation (ADC2) for automated signal filtering and threshold detection without CPU intervention.
System Logic Customization
Use the Configurable Logic Cell (CLC) to create custom hardware logic gates and state machines within the MCU.
Legacy System Upgrades
Replace older 8-bit controllers in existing through-hole designs with a modern, higher-speed processor that supports 64MHz operation.

Getting Started

Develop applications using the MPLAB X IDE and the XC8 compiler provided by Microchip. The Curiosity Nano or PIC18F26Q43 Curiosity High Pin Count (HPC) development boards are recommended for evaluation, though this SPDIP part can be used directly on a breadboard with a PICkit 4 or MPLAB Snap programmer.
