Complete your designs faster with AVR® microcontrollers (MCUs). Offering unsurpassed performance, power efficiency and flexibility, they are an excellent choice for a variety of embedded system designs. Their combination of easily customizable peripherals and the industry's most code-efficient architecture enable you to bring multiple functions to a single chip with minimal programming. We also offer industry-leading development tools and design support to help you get your design to market quickly. After your products have launched, the large AVR MCU family allows you to reuse your knowledge to improve and enhance your offerings, making it easy and cost-effective to expand into new markets.

AVR DB Family

Take advantage of the integrated level shifters and three highly configurable op amps to implement real-time control functionality in a variety of industrial control, home appliance, automotive, IoT and other applications.

AVR DA Family

Improve system response for complex single-chip control applications enabled by a combination of large memory and interconnectable Core Independent Peripherals.

ATtiny1607 Family

Improve performance and reduce the complexity of your real-time control applications with high-speed analog and hardware-based Core Independent Peripherals.

ATtiny1627 Family

Improve real-time performance with high-speed measurement, or measure small amplitude signals in harsh and noisy environments with the 12-bit differential ADC and Programmable Gain Amplifier (PGA).
