The ATXMEGA256A3-AUR is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It features 256KB of in-system self-programmable Flash memory, 16KB internal SRAM, and 4KB EEPROM. Operating at a maximum clock frequency of 32 MHz, it supports a supply voltage range of 1.6V to 3.6V. The device includes a rich set of peripherals such as a four-channel DMA controller, an eight-channel event system, seven 16-bit timer/counters, seven USARTs, three SPI interfaces, and two I2C-compatible two-wire interfaces.
For analog functionality, it integrates two 12-bit, 2 Msps ADCs with a total of 16 channels, one two-channel 12-bit DAC, and four analog comparators. The microcontroller also incorporates a brown-out detect/reset, power-on reset, and a programmable watchdog timer. It offers 50 programmable I/O lines and is available in a 64-lead TQFP package (14x14mm) for surface-mount assembly. The device is designed for industrial control, factory automation, and hand-held battery applications, providing a balance of performance, memory, and connectivity options.
