Microcontrollers for Real-Time Control, Connectivity and HMI Applications

The AVR DA family brings real-time control functionality and easy capacitive touch to the low-power performance of AVR® microcontrollers (MCUs). It pairs the latest Core Independent Peripherals (CIPs) with a robust Intelligent Analog portfolio to create a device that not only excels as a stand-alone processor but also as a companion MCU in designs that demand precision. The high memory density of the AVR DA family makes these MCUs well suited for both wired and wireless communication stack intensive functions.

The family uses the latest Core Independent Peripherals with low-power features and 5V operation for increased noise immunity. The Event System and Configurable Custom Logic (CCL) peripherals, along with Intelligent Analog peripherals, like 12-bit differential Analog-to-Digital Converter (ADC), Zero-Cross Detect (ZCD), 10-bit Digital-to-Analog Converter (DAC) and the latest-generation Peripheral Touch Controller (PTC) with Driven Shield technology, make the AVR DA family ideal for low-latency control applications and capacitive touch user interfaces. The AVR DA family is designed to bring capacitive touch sensing and real-time control functions to industrial control, home appliance products, automotive, Internet of Things (IoT) and other applications.
