The new PIC16F18446 family of microcontrollers are ideal components for use in sensor nodes.
Designed with flexibility in mind, PIC16F18446 and its integrated Analogue-to-Digital Converter with Computation (ADCC) runs from 1.8V to 5V, providing compatibility with the majority of both analogue output sensors and digital sensors.
The 12-bit ADCC does its filtering autonomously, providing more accurate analogue sensor readings and ultimately higher-quality end-user data.
Because the ADCC has the ability to wake the core only when needed, instead of on a pre-determined schedule, the power consumption of the system is lowered, making this MCU ideal for battery-powered applications.
This power saving capability also enables sensor nodes to run on small batteries, decreasing end-user maintenance costs and the overall design footprint.
The introduction of the ATmega4809 brings a new series of megaAVR® microcontrollers that were designed to create highly-responsive command and control applications.

The processing power of the integrated high-speed Analogue-to-Digital Converter (ADC) enables faster conversion of analogue signals resulting in deterministic system responses.
As the first megaAVR device to include Core Independent Peripherals (CIPs), the ATmega4809 can execute tasks in hardware instead of through software.
This decreases the amount of code and can tremendously reduce software efforts for faster time to market.
The ATmega4809 can also be added to a system to offload functions from more complex microprocessor (MPU)-based designs. By using CIPs to execute command and control tasks in the MCU instead of the MPU, the risk of delayed responses is decreased, resulting in a better end-user experience.
The ATmega4809 has been selected to be the onboard microcontroller of a next-generation Arduino board.
The addition of the ATmega4809 to this board allows developers to spend less time coding and more time creating. The hardware-based CIPs enable the creation of designs which are more efficient, while making the transition from project to production-ready easier than ever before.
“The adoption of the ATmega4809 in the next-generation Arduino board strengthens our partnership and brings the benefits of CIPs and Intelligent Analogue to the Arduino platform,” said Steve Drehobl, vice president of Microchip’s 8-bit MCU business unit.
The new PIC16F18446 microcontrollers are compatible with MPLAB PICkit™ 4 (PG164140), Microchip’s latest in-circuit tool for low-cost programming and debugging.
The Curiosity development board (DM164137), a feature-rich rapid prototyping board, can also be used to start development with these MCUs.
Both development tools are supported by the MPLAB X Integrated Development Environment (IDE) and the cloud-based MPLAB Xpress IDE. Additionally, MPLAB Code Configurator (MCC), a free software plug-in, provides a graphical interface to configure peripherals and functions for any application.
Designers wanting to begin development immediately can download rapid-start code examples and order a complimentary MPLAB Xpress PIC16F18446 development board, available for a limited time.
The PIC16F18446 and ATmega4809 devices are available today in a variety of memory sizes, pin counts and package options in volume production quantities.
The MPLAB PICkit 4 programmer/debugger, the Curiosity development board and the ATmega4809 Xplained Pro evaluation kit are also available.
