The high-performance 32-bit AVR® UC3 RISC microcontroller is designed for cost-sensitive embedded applications that require low power consumption, high code density, and high performance.

The microcontroller's memory protection unit (MPU) and fast, flexible interrupt controller support the latest real-time operating systems. The secure access unit (SAU) with MPU provide enhanced security and integrity. A rich set of DSP instructions delivers higher computational capability.

The microcontroller embeds state-of-the-art picoPower® technology for ultra-low power consumption. A combination of power control techniques brings active current consumption down to 165µA/MHz and leakage down to 9nA while still retaining a bank of backup registers. The device offers a wide range of trade-offs between functionality and power consumption to reach the lowest possible power usage for the application's required feature set.

Atmel's UC3 microcontrollers are ideally suited for use in mobile devices due to their low current consumption. Sensor fusion processing is a key area where these devices can be used to differentiate products, and with Atmel's extensive range of sensor partners it is easy to add realtime motion processing to enrich the user experience. Atmel also has a range of devices with maXFusion™ sensor hub technology, which combines Atmel's low-power AVR devices with built-in sensor fusion code.
