对容量和性能的进一步提升

如果您的设计需要一些其他功能，则您需要 megaAVR。megaAVR 是需要大量代码的应用的理想之选，提供性能高达 20MIPS 的重要程序和数据存储器。创新性的 picoPower 技术将功耗降至最低。所有的 megaAVR 均具有自编程能力，可以实现快速、安全的、高成本效益的在线升级。您甚至可以在运行应用的同时升级闪存。

基于业界顶级、已经过实践检验的技术，megaAVR 系列在存储器、管脚数和外设方面提供最广泛的器件选择。您既可以选择通用器件，也可以选择具有专用外设的型号，例如，USB、或 LCD 控制器、或 CAN、LIN 和功率级控制器。在 megaAVR 产品系列中，您可以轻而易举地找到与您的项目完美契合的产品。

关键特性

  • 丰富的产品系列 — megaAVR 针对不同的存储器、管脚数和外设需求提供了最丰富的器件供您选择，方便您跨项目重用代码和传承知识。
  • picoPower 技术 — 部分 megaAVR 具有超低功耗和单独可选的低功耗休眠模式，使其成为了电池供电应用的理想之选。
  • 高度集成 — megaAVR 具有片上闪存、SRAM、内部 EEPROM、SPI、TWI 和 USART、USB、CAN 和 LIN、看门狗定时器、可供选择的内部或外部精度振荡器以及通用 I/O 管脚，从而简化了您的设计，减少了物件需求。
  • 模拟功能 — 先进的模拟功能（如 ADC 和 DAC）、内置温度传感器和内部基准电压、欠压检测器、快速模拟比较器和可编程的模拟增益放大器。借助这种高度集成的器件，您设计时将只需要极少的外部模拟元件。
  • 快速开发 — megaAVR 微控制器使用强大的系统内编程和片上调试，加快了开发速度。此外，系统内编程还简化了生产线编程和现场升级。
