The ATXMEGA256A3-AU is a high-performance, low-power 8/16-bit microcontroller from the Atmel AVR XMEGA series. It features 256 KB of in-system self-programmable Flash memory, 8 KB of EEPROM, and 16 KB of internal SRAM. The device operates at a voltage range of 1.6 to 3.6V and supports clock speeds up to 32 MHz. This microcontroller includes a variety of peripheral features such as a four-channel DMA controller, eight-channel event system, seven 16-bit timer/counters, and multiple communication interfaces including seven USARTs, three SPI, and two two-wire interfaces. It also has two 12-bit analog-to-digital converters and a digital-to-analog converter, making it suitable for applications requiring precise analog signal processing. The ATXMEGA256A3-AU is designed for a wide range of applications including industrial control, climate control, factory automation, and medical applications. However, it is noted that this part is not recommended for new designs, with a suggestion to consider the XMEGA A3U series instead.
