ATUC64D3-A2UT

The ATUC64D3-A2UT is a 32-bit System-on-chip Microcontroller based on the AVR32UC RISC processor running at frequencies up to 48MHz. It features 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. 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 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.
