Microchip's
AVR DA family brings real-time control functionality and easy capacitive touch to the low-power performance of AVR MCUs. It pairs the latest core independent peripherals (CIPs) with a robust integrated 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.
This family uses the latest CIPs with low-power features and 5 V 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 converters (ADCs), zero-cross detect (ZCD), 10-bit digital-to-analog converters (DACs), 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. The AVR DB MCUs are an excellent option for level-shifted, bidirectional communication with devices on a different power domain.
