ATXMEGA64A1U-AUR Description

Short technical summary and product information.

The ATXMEGA64A1U-AUR is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It features 64KB of in-system self-programmable Flash memory, 4KB SRAM, and 2KB EEPROM. The device operates at a maximum frequency of 32MHz and supports a supply voltage range of 1.6V to 3.6V.

 

This microcontroller is equipped with 78 I/O lines, a four-channel DMA controller, an eight-channel event system, and eight 16-bit timer/counters with advanced waveform extension. Connectivity includes eight USARTs (with IrDA support on one), four SPI interfaces, four two-wire interfaces (I2C/SMBus compatible), and a USB 2.0 full/low-speed device interface. It also includes an AES/DES crypto engine and CRC-16/CRC-32 generator.

 

The device integrates two 16-channel 12-bit ADCs and two 2-channel 12-bit DACs. It is available in a 100-TQFP package (14x14mm) for surface-mount assembly. Operating temperature range is -40°C to +85°C.
