【产品简介】
The AVR XMEGA delivers a leading combination of real time performance, integration and power efficiency. The highly integrated design minimizes your bill of materials in a broad range of applications. This includes features like AES and DES crypto, high-speed analog modules, flexible Timer/Counters, multiple communication modules and types, and efficient power management. The DMA controller, innovative event system ensure predictable real time performance even with high load, and push the boundaries for high-performance 8/16-bit MCUs.
To speed up development, all AVR XMEGA devices are code-compatible. You can maintain one code base and re-use it across multiple projects.
