The Microchip Technology ATXMEGA256A3BU-MHR is a high-performance 8/16-bit AVR XMEGA microcontroller designed for complex embedded systems. It features 256KB of in-system self-programmable Flash memory, 16KB internal SRAM, and 4KB EEPROM for non-volatile data storage. The device operates at up to 32MHz and supports a wide supply voltage range of 1.6V to 3.6V, enabling low-power operation. Connectivity options include I²C, IrDA, SPI, UART/USART, and USB, making it suitable for communication-centric applications. The microcontroller integrates a 16-channel 12-bit ADC and a 2-channel 12-bit DAC for analog interfacing. It is housed in a 64-VFQFN exposed pad package (64-QFN 9x9mm) and is intended for surface-mount assembly. The ATXMEGA256A3BU-MHR includes peripherals such as DMA, brown-out detection, power-on reset, PWM, and a watchdog timer, and it operates over an industrial temperature range of -40°C to +85°C.
The operating voltage range is 1.6V to 3.6V.
It is available in a 64-VFQFN exposed pad package (also designated as 64-QFN 9x9mm).
The operating temperature range is -40°C to +85°C.
The component is marked as RoHS3 compliant based on available data, but this has not been externally verified.
The program memory is 256KB (128K x 16) of Flash.
It has 47 programmable I/O pins.
