![]() The on-chip ZCD peripheral can take the signal directly from the AC main with only a current-limiting resistor (and/or capacitor in some cases) in series with the input. The AVR DA depending on the package selected, can have up to 3 Zero Cross Detectors. It is very useful when monitoring AC waveforms for purposes such as TRIAC dimming, AC period measurement and minimizing EMI caused by switching transients. The ZCD is an intelligent peripheral that detects when an Alternating Current (AC) signal crosses through the ground potential. It is suited for industrial control, home appliance, automotive and Internet of Things (IoT) applications. The AVR DA family pair the latest digital peripherals with a robust Intelligent analog portfolio to create a device that not only excels as a standalone processor but also as a companion MCU in designs that demand precision. This will add an extra dimension to the already well-trusted AVR platform that the design community has come to know and appreciate, thereby allowing for a greater degree of creativity to their applications. It is the first device to be jointly developed using design expertise and IP from both of Microchip's R&D centres located at Chandler (Arizona) and Trondheim (Norway).Īll new AVR devices will have an extensive focus on providing powerful and highly capable core independent analog features and functions going forward. The recently released AVR DA family of microcontrollers from Microchip heralds the next generation of AVR MCUs. ![]()
