Atmel公司的AT32UC3A是采用AVR32 UC RISC处理器的系统级芯片(SoC)微控制器,工作频率高达66MHz,具有低功耗,高的代码密度和高性能,可实现存储器保护单元(MPU)和快速灵活的中断控制,支持现代操作系统和实时操作系统,采用DSP指令集可获得更高的计算功能,非常适合坞站,USB海量存储,SD卡播放,汽车立体声,USB扬声器,以及各种音/视频设备.本`文介绍了AT32UC3A主要特性, 方框图和UC3-A3 XPLAINED评估板主要特性与方框图.

The AT32UC3A is a complete System-On-Chip microcontroller based on the AVR32 UC RISC processor running at frequencies up to 66 MHz. 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 capabilities are achievable using a rich set of DSP instructions.

The AT32UC3A incorporates on-chip Flash and SRAM memories for secure and fast access. For applications requiring additional memory, an external memory interface is provided on AT32UC3A0 derivatives.
