ATXMEGA64A4U-AN概述
Atmel AVR XMEGA 微控制器能够为 8/16 位 MCU 应用提供实时性能、高集成和低功率消耗的最佳可能组合。
Atmel AVR XMEGA 设备采用高级模拟到数字转换器 (ADC),可实现高速和高分辨率。 这些 ADC 提供多达四个转换通道,带有不同的结果寄存器,可进行不同设置和配置过程。 因为不同软件模块可独立访问和使用一个 ADC,因此更易于使用。

事件系统便于交互外围信号,可实现短期和 100% 的可预测响应时间。 这可确保实时控制,还可卸载 CPU,因为每次使用一个事件,就会消除一个上下文切换的中断。 大多数的外围设备和 DMA 控制器可连接到事件系统。 相反,AVR XMEGA E 系列具有一个异步外设事件系统。

AVR XMEGA 的 4 通道直接内存访问 (DMA) 控制器可用于在任意组合的数据存储器和外围设备之间进行快速、独立于 CPU 的数据传输。
AVR XMEGA 设备使用 Atmel AVR CPU。 指令集和 CPU 设计经调优可最大程度降低代码尺寸和最大程度提高执行速度。 真正单周期执行算术和逻辑操作意味着 AVR XMEGA 微控制器每 MHz 接近 1 MIPS。 快速访问寄存器文件带 32 x 8 位通用工作寄存器,可直接连接到算术逻辑单元 (ALU)。 单时钟循环期间,ALU 可被馈送两个任意寄存器,执行所需操作,然后回写结果。 它可以提供 8、16 和 32 位算术高效支持。

Data Sheet
Introduction
The Microchip AVR
®
XMEGA
®
is a family of low power, high performance, and peripheral rich 8/16-bit
microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single
clock cycle, the AVR XMEGA devices achieve CPU throughput approaching one million instructions per
second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus
processing speed.
