Overview

The PIC18F27Q10-I/SP is a high-performance 8-bit microcontroller featuring 128KB of Flash memory and a 64MHz internal oscillator. It belongs to the PIC18 Q10 family, which emphasizes Core Independent Peripherals (CIPs) and eXtreme Low-Power (XLP) technology for efficient, automated system operation. This specific variant comes in a 28-pin SPDIP package, making it ideal for through-hole prototyping and educational environments.

Why Choose This Part

This MCU offers a massive 128KB Flash in an 8-bit architecture, providing ample space for complex firmware and communication stacks. The inclusion of Core Independent Peripherals like the Complementary Waveform Generator (CWG) and Windowed Watchdog Timer (WWDT) allows for safety-critical tasks to run with minimal CPU intervention. Its 28-pin DIP package is specifically advantageous for breadboard prototyping and easy soldering in low-volume production.

Applications

Industrial Sensor Nodes
Utilizes the 10-bit ADC with Computation (ADC2) and Zero-Cross Detect for precise signal conditioning and power monitoring.
Battery-Powered Wearables
Leverages XLP technology and a 0.5uA sleep current to extend battery life in portable electronics.
Hardware Logic Offloading
Uses Configurable Logic Cells (CLC) to implement custom hardware logic functions without taxing the CPU core.
Touch-Enabled Interfaces
Features integrated Capacitive Voltage Divider (CVD) support for robust touch sensing and button implementation.

Getting Started

Develop for this MCU using Microchip's MPLAB X IDE and the XC8 Compiler. For rapid prototyping, the MPLAB Code Configurator (MCC) provides a graphical interface to initialize peripherals and generate C code. Hardware debugging can be performed using an MPLAB PICkit 4 or Snap debugger connected via the ICSP pins.
