ATXMEGA128A1U-AU Description

Short technical summary and product information.

The Microchip Technology ATXMEGA128A1U-AU is an 8/16-bit microcontroller based on the AVR XMEGA architecture. It offers 128KB of in-system self-programmable flash memory and 8KB of internal SRAM, along with 2KB of EEPROM.

 

This device operates at a maximum frequency of 32MHz, executing instructions in a single clock cycle for efficient processing. It supports a wide range of connectivity options including EBI/EMI, I²C, IrDA, SPI, UART/USART, and USB. The microcontroller includes peripherals such as a DMA controller, event system, multiple timer/counters, and a USB device interface.

 

With 16 analog-to-digital converter channels (12-bit) and 4 digital-to-analog converter channels (12-bit), it is suitable for applications requiring data conversion. The operating temperature range is -40°C to 85°C (TA).

 

The ATXMEGA128A1U-AU is supplied in a 100-TQFP (14x14) package and is designed for surface mounting. Its operating voltage is between 1.6V and 3.6V.
