Robust MCUs for Compact Embedded Designs

The PIC18-Q40 family of microcontrollers (MCUs) makes it easy for you to customize your next space-constrained design. Packing a high level of sophistication into a small 14- or 20-pin package, these MCUs combine powerful, versatile and highly configurable Core Independent Peripherals (CIPs) with advanced interconnection capabilities to allow you to create custom application functions. Our comprehensive development tool suite with its Graphical User Interface (GUI) environment makes it easy to quickly customize combinations of CIPs and generate application code. These MCUs are well suited for remote medical care devices, wearables, consumer, automotive, industrial and Internet of Things (IoT). If you need the same level of MCU performance with additional analog features, PIC18-Q41 MCUs are an ideal solution. 

Getting Started


Take your next idea to market with a cost-effective development board that you can keep in your pocket. With its full programming and debugging capabilities, the PIC18F16Q40 Curiosity Nano Evaluation kit (EV70C97A) offers complete support for your next design. 

The PIC18-Q40 family is designed to integrate with MPLAB® Code Configurator (MCC), a free software plug-in for our award-winning MPLAB X Integrated Development Environment (IDE), that provides a graphical interface to easily configure peripherals and functions specific to your application. Code examples are also available to help you immediately start your development.
