ATXMEGA64A4U-AU Description

Short technical summary and product information.

The ATXMEGA64A4U-AU is a member of Microchip's AVR XMEGA family of low-power, high-performance 8/16-bit microcontrollers. It features an AVR core with a maximum clock speed of 32MHz, enabling up to 32 MIPS throughput. The device includes 64KB of in-system self-programmable flash program memory, 4KB of SRAM, and 2KB of EEPROM for data storage.

 

Connectivity options include I2C, IrDA, SPI, UART/USART, and a USB 2.0 full-speed/low-speed device interface with 32 endpoints. The microcontroller integrates a four-channel DMA controller, a five-channel event system, and five 16-bit timer/counters with high-resolution extensions. It also includes a 12-channel 12-bit ADC, a 2-channel 12-bit DAC, and two analog comparators.

 

The ATXMEGA64A4U-AU operates from a supply voltage of 1.6V to 3.6V and over an industrial temperature range of -40°C to 85°C. It is housed in a 44-pin TQFP package (10x10mm) with surface mount mounting. Additional peripherals include brown-out detection, power-on reset, and a watchdog timer.
