The UC3D is a complete System-On-Chip microcontroller based on the AVR32UC RISC processor running at frequencies up to 48MHz. AVR32UC 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 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 Peripheral Direct Memory Access (DMA) controller enables data transfers between peripherals and memories without processor involvement. The Peripheral DMA controller drastically reduces processing overhead when transferring continuous and large data streams. The Power Manager improves design flexibility and security. Power monitoring is supported by on-chip Power-On Reset (POR), and Brown-Out Detector (BOD). The device features several oscillators, such as Oscillator 0 (OSC0), 32 KH–Oscillator and system RC oscillator (RCSYS), and two Phase Lock Loop (PLL). Either of these oscillators/PLLs can be used as source for the system clock. The Watchdog Timer (WDT) will reset the device unless it is periodically serviced by the software. This allows the device to recover from a condition that has caused the system to be unstable. The Asynchronous Timer (AST) combined with the 32KH–crystal oscillator supports powerful real-time clock capabilities, with a maximum timeout of up to 136 years. The AST can operate in counter mode or calendar mode. The 32KH–crystal oscillator can operate in a 1- or 2-pin mode, trading pin usage and accuracy. The Frequency Meter (FREQM) allows accurate measuring of a clock frequency by comparing it to a known reference clock.
