The AT32UC3L is a complete System-On-Chip microcontroller based on the AVR32 UC RISC processor running at frequencies up to 50MHz. AVR32 UC is a high-performance 32-bit RISC microprocessor core, designed for cost-sensitive embedded applications, with particular  emphasis on low power consumption, high code density, and high performance.

The processor implements a Memory Protection Unit (MPU) and a fast and flexible interrupt controller for supporting modern operating systems and real-time operating systems.

Higher computation capability is achieved using a rich set of DSP instructions.

The AT32UC3L embeds state-of-the-art picoPower technology for ultra-low power consumption. Combined power control techniques are used to bring active power as low as 0.5mW/MHz, and leakage down to 100nA while still retaining a bank of backup registers. The device allows a wide range of trade-offs between functionality and power consumption, giving the user the ability to reach the lowest possible power consumption with the feature set required for the application.
