Atmel® AVR® microcontrollers (MCUs) offer robust performance, low power, high-speed, connectivity, and high system integration. Based on a single-cycle RISC engine that combines a rich instruction set, AVR MCUs deliver close to 1 MIPS (Million Instructions per Second) per megahertz and are optimized for minimum code size and maximum computing performance. They are ideal for a broad range of applications, including industrial control, wireless, medical and utility metering, communication gateways, sensor control, appliances (white goods, small kitchen appliances, personal healthcare, etc.), and portable battery-powered products. Plus, AVR MCUs enable you to get your products to market quickly.

AVR Freaks, a strong community following of over 400,000 engineers for more than 15 years — lets you interact with other engineers on technical discussions and forums related to AVR MCUs.

Whether you are working on new, existing or legacy designs, the wide range of Atmel AVR devices provides the latest features and functionality. These devices also deliver high integration, the lowest power consumption, a comprehensive set of powerful integrated peripherals, and world-class ease of use.


High Integration

Integrating more functions on the chip reduces board size, simplifies system design, and reduces system complexity and total cost. High integration combined with small packages makes it possible to create smaller footprint designs. Atmel AVR MCUs offer a high level of integration that includes on-chip Flash memory, SRAM, EEPROM, internal pull-up resistors, precision oscillators, watchdog timer, brownout detector, and GPIO/PWM (pulse-width modulation) pins for application use. Advanced on-chip analog capabilities include an internal temperature sensor, analog comparators, multiple 8-bit, 10-bit or 12-bit ADC (analog-to-digital converter) input channels, multiple 8-bit, 10-bit or 12-bit DAC (digital-to-analog) output channels and programmable-gain analog amplifiers. Several Atmel MCUs feature a peripheral called Custom Logic, which can be configured to combinatorial or sequential logic functions capable of replacing external logic circuitry.


Easy to Use

AVR MCUs are designed with ease of use in mind, which includes everything from peripherals to datasheets to tools. Atmel offers a high-quality, easy-to-use tool chain for the full range of AVR families. Available for free, the Atmel Studio development platform enables code development in C or assembly, provides cycle-accurate simulation, and integrates seamlessly with AVR starter kits, programmers, debuggers, evaluation kits, and reference designs. This results in faster development, a more productive development team, and rapid time to market.


Low Power

In order to meet the challenging requirements of portable and battery-operated applications, Atmel has combined years of low power research and developed Atmel picoPower® technology. This technology enables AVR microcontrollers to reduce power consumption in both Sleep and Active modes, and achieve the industry's lowest power consumption of 500nA @ 1.8V with RTC running and 100nA with full SRAM retention.
