ATXMEGA128A3-AUR Description

Short technical summary and product information.

The ATXMEGA128A3-AUR is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It features 128KB of in-system self-programmable flash memory, 8KB of internal SRAM, and 2KB of EEPROM. The device operates at a maximum speed of 32 MHz with a supply voltage range of 1.6V to 3.6V. It includes a rich set of peripherals such as a DMA controller, event system, seven timer/counters with high-resolution extensions, seven USARTs, three SPI interfaces, two I2C-compatible two-wire interfaces, and dual 12-bit ADC/DAC converters. The microcontroller also supports brown-out detection, power-on reset, and multiple sleep modes for low-power operation.

 

The ATXMEGA128A3-AUR is housed in a 64-lead TQFP package (14x14 mm) and is designed for surface-mount assembly. It operates over an industrial temperature range of -40°C to +85°C. Typical applications include industrial control, climate control, handheld battery-powered devices, factory automation, and ZigBee communication nodes.
