ATXMEGA128A1U-AN Description

Short technical summary and product information.

The Microchip ATXMEGA128A1U-AN is a high-performance, low-power 8/16-bit AVR microcontroller based on the AVR enhanced RISC architecture. It features 128KB of in-system self-programmable flash memory, 8KB of internal SRAM, and 2KB of EEPROM.

 

This microcontroller operates at a maximum frequency of 32MHz and supports a wide operating voltage range of 1.6V to 3.6V. It offers a rich set of peripherals including a four-channel DMA controller, eight-channel event system, multiple timer/counters, a USB device interface (USB 2.0 full speed and low speed compliant), eight USARTs, four two-wire interfaces (I2C/SMBus compatible), and four serial peripheral interfaces (SPIs).

 

Additional features include two 12-bit Analog-to-Digital Converters (2Msps) and two 12-bit Digital-to-Analog Converters (1Msps). The device is available in a 100-lead TQFP package, suitable for surface mount applications. It operates within an industrial temperature range of -40°C to 105°C.

 

The ATXMEGA128A1U-AN is designed for applications requiring a balance of performance, low power consumption, and rich peripheral integration. Its extensive connectivity options and robust feature set make it suitable for a wide range of embedded systems.
