AT32UC3B1256-AUT

AVR Microcontroller, High performance, Low Power, AT32 Family AT32UC3B Series Microcontrollers

The AT32UC3B1256-AUT is a 32-bit complete System-On-Chip Microcontroller based on the AVR32 UC RISC processor running at frequencies up to 60MHz. 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 AT32UC3B incorporates on-chip Flash and SRAM memories for secure and fast access. The Peripheral Direct Memory Access controller enables data transfers between peripherals and memories without processor involvement. PDCA drastically reduces processing overhead when transferring continuous and large data streams between modules within the MCU.
