Whether used for entry-level embedded development, as a main controller for connecting applications, or as an additional component to lighten the load of large systems, the role of 8-bit microcontrollers (MCUs) is continuously expanding. Although hardware and software tools such as core-independent peripherals (CIPs), smart analog, and MPLAB® Code Configurator are not inherently complex or difficult to implement, their impact cannot be overlooked. They can enhance processing capabilities while reducing code volume, power consumption, and the design workload required for rapid market entry. In light of this, Microchip Technology Inc., a global leader in integrated microcontrollers, mixed-signal, analog devices, and flash patent solutions, has launched two new MCU series designed with customer innovation in mind.
The new PIC16F18446 series microcontroller is an ideal device for sensor nodes. With flexibility in mind, the PIC16F18446 and its integrated computing-capable analog-to-digital converter (ADC2) operate within a voltage range of 1.8V to 5V, making it compatible with most analog output sensors and digital sensors. This 12-bit ADC2 can automatically filter, providing more accurate readings from analog sensors and ultimately delivering higher-quality end-user data. Because this ADC2 can wake the core on demand rather than on a scheduled basis, it reduces system power consumption, making this MCU very suitable for battery-powered applications. Additionally, this energy-saving feature allows sensor nodes to operate on small batteries, thus reducing maintenance costs and overall design footprint for end users.
The recently released ATmega4809 is part of the new megaAVR® microcontroller series, designed for high-response command and control applications. Its integrated high-speed analog-to-digital converter (ADC) has powerful processing capabilities that accelerate the conversion speed of analog signals, resulting in deterministic system responses. As the first megaAVR device to include core-independent peripherals (CIPs), the ATmega4809 can perform tasks via hardware rather than software. This reduces code volume and significantly lowers software workload, thereby speeding up time-to-market. For example, the configurable custom logic (CCL) peripheral can connect the ADC to custom external trigger combinations via hardware without interrupting the core, thus shortening response time while reducing power consumption. Additionally, the ATmega4809 can be added to systems to provide various functionalities that only microprocessor-based (MPU) designs can offer. By using CIPs in the MCU to execute command and control tasks without using an MPU, the risk of response delay is greatly reduced, leading to a better end-user experience.
Due to its outstanding performance, the ATmega4809 has been selected as the onboard microcontroller for the next generation of Arduino development boards. By adding the ATmega4809 device to this development board, developers can save time writing code, allowing them to focus more on innovative areas. The hardware-based CIPs enable more efficient design creation, and the transition from project development to mass production is now easier than ever.
Steve Drehobl, Vice President of Microchip’s 8-bit MCU Product Division, stated: “The selection of the ATmega4809 device for the next generation of Arduino development boards not only strengthens the collaboration between the two companies but also brings the advantages of CIPs and smart analog to the Arduino platform.”
Development Tools
The new PIC16F18446 microcontroller series is compatible with the MPLAB PICkit™ 4 (part number: PG164140), which is Microchip’s latest online tool for low-cost programming and debugging. The Curiosity development board (part number: DM164137) is a feature-rich rapid prototyping board that also assists designers in developing based on these MCUs. Both development tools are supported by the MPLAB X integrated development environment (IDE) and the MPLAB Xpress cloud IDE. Additionally, Microchip provides the MPLAB Code Configurator (MCC). As a free software plugin, it offers a graphical interface to help designers configure various peripherals and functions for any application. Designers looking to start development immediately can download quick-start code examples and rush to order the limited-time free MPLAB Xpress PIC16F18446 development board.
With the ATmega4809 Xplained Pro (part number: ATmega4809-XPRO) evaluation toolkit, designers can quickly complete prototype development based on the ATmega4809. This USB-powered toolkit features touch buttons, LEDs, quick-install expansion headers, and an onboard programmer/debugger seamlessly integrated with Atmel Studio 7 IDE and Atmel START. Atmel START is a free online tool for configuring peripherals and software to accelerate development work.
The Curiosity development board and ATmega4809 Xplained Pro evaluation toolkit include a mikroBUS™ compatible socket, making it easy to add sensors, actuators, or communication interfaces from the Mikroelektronika click boards™ expansion library.
Supply
The PIC16F18446 and ATmega4809 series devices are now available in volume production, offering various storage capacities, pin counts, and packaging options. The MPLAB PICkit 4 programmer/debugger, Curiosity development board, and ATmega4809 Xplained Pro evaluation toolkit are also now available.
