Microcontrollers for Improved Sensor Interface Designs

The PIC18-Q41 family of microcontrollers (MCUs) integrates intelligent analog capabilities with powerful Core Independent Peripherals (CIPs) for small, high-performance data acquisition and sensor interfacing applications. These MCUs are uniquely equipped with an Operational Amplifier (OPA), a 12-bit Analog-to-Digital Converter with Computation (ADCC) and two 8-bit Digital-to-Analog Converters (DACs) to provide you with an ideal starting point for any design where signal amplification, filtering and conditioning is needed. Going beyond hardware with our expansive software tool library, you can easily configure peripherals and functions, generate application code and simulate analog circuits prior to hardware prototyping to reduce your development time and speed up your time to market. PIC18-Q41 MCUs are well suited for many applications including medical devices, Internet of Things (IoT) edge nodes, wearables, LED lighting, home automation systems, automotive and motor control applications, and industrial process control. If a cost-effective MCU with comparable performance is needed, PIC18-Q40 MCUs are a good option. 

Getting Started


Take your next idea to market with a development board that you can keep in your pocket. With full program and debug capabilities, the PIC18F16Q41 Curiosity Nano Evaluation Kit offers complete support for your next design.

The PIC18-Q41 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 and analog simulations are also available to help you immediately start your development.

Made for Medical


The PIC18-Q41 family’s unique combination of peripherals makes it an excellent choice for medical devices, especially for applications such as Internet of Medical Things (IoMT) edge nodes, telehealth devices, medical wearables, drug delivery devices and motor control applications. When you combine the capabilities of this family with our experience as an embedded solutions partner to thousands of medical device companies, you can rest assured that your medical product is prepared to go the extra mile.
