For embedded applications, system performance is much more than a good MIPS number. It is important to have powerful peripherals and features for an MCU that allow the application to run smoothly with minimum power consumption.
The XMEGA AU is a family of low-power, high performance, and peripheral-rich CMOS 8-bit MCUs based on the AVR enhanced RISC architecture. All the AVR XMEGA AU are 100% pin- and code-compatible across all devices from the smallest to the largest device. It is possible to develop with any XMEGA AU device, and switch to any other XMEGA AU device later without having to change any code. Figure 1 shows the important peripherals of an XMEGA AU MCU usually required for the IoT applications.
In this section, the most highlighting features of XMEGA AU MCU devices are described, which are essential for IoT applications.
