• Arithmetic performance — Integrated FPU increases precision and dynamic range in digital signal processing.
• High data throughput — Peripheral DMA, multi-layered databus and large on-chip SRAM remove bottlenecks in high-speed communication.
• Low power consumption — picoPower® technology delivers the industry''s lowest power consumption in active and sleep modes.
• Software Library — All UC3 devices are supported by AVR Software Framework, a complete library of device drivers and middleware.

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.
