Icon Performance

High Performance

As consumer products become increasingly complex and include more advanced features like touch interfaces and wireless connectivity, the need for performance is growing. In many cases the design foundation of Atmel MCUs makes them inherently more efficient, such as the single-cycle execution in AVR MCUs that relies on an instruction set originally built and optimized for C-code versus one optimized for assembly language.

Icon Power

Low Power Consumption

Atmel leads the industry in delivering low-power embedded solutions, including the world’s lowest-power 32-bit MCU. This efficiency comes not only from more efficient core architecture and factors such as smaller program size but also a number of Atmel power-saving innovations.

Icon Easeofuse

Ease of Use

Atmel MCUs offer advantages such as compatible source code and an ecosystem that includes free software along with an integrated development environment, which connects seamlessly to Atmel debuggers, development kits and very-low-cost yet full-featured evaluation boards. Atmel devices also deliver a number of innovations to enhance ease of use, provide the maximum flexibility, while minimizing the need for expensive additional components to reduce overall design costs.

Icon Connect


Atmel MCUs embed a wide range of advanced communication peripherals and functions, making them ideal for a variety of connected applications. Atmel MCUs seamlessly integrate RF and Wi-Fi providing superior connectivity and making them the perfect choice for today’s smart, connected products, including products in the rapidly growing Internet of Things (IoT) market.
