The AT32UC3A0512-ALUT is a complete System-On-Chip Microcontroller based on the processor running at frequencies up to 66MHz. It 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 capabilities are achievable using a rich set of DSP instructions. The Peripheral Direct Memory Access controller (PDCA) drastically reduces processing overhead when transferring continuous and large data streams between modules within the MCU. The on-chip Brown-Out Detector monitors the power supply, the CPU runs from the on-chip RC oscillator or from one of external oscillator sources, a Real-Time Clock and its associated timer keeps track of the time.
