ATXMEGA64A3U-MHR Description

Short technical summary and product information.

The ATXMEGA64A3U-MHR is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It integrates a 32MHz AVR core with 64KB of in-system self-programmable flash memory, 4KB SRAM, and 2KB EEPROM. The device supports a supply voltage range of 1.6V to 3.6V and operates over -40°C to +85°C.

 

This microcontroller is equipped with a rich set of peripherals including a four-channel DMA controller, an eight-channel event system, seven 16-bit timer/counters with high-resolution and advanced waveform extensions, and a USB 2.0 full-speed device interface. On-chip analog features include dual 12-bit ADCs (16 channels, 2 Msps), a 12-bit DAC (2 channels, 1 Msps), four analog comparators, and a crypto engine supporting AES and DES encryption.

 

Connectivity is provided via I²C, IrDA, SPI, UART/USART, and USB interfaces, along with 50 general-purpose I/O pins. The device includes brown-out detection, power-on reset, and programmable watchdog timer. It is available in a 64-VFQFN exposed pad package (9x9mm) and is supplied in tape and reel packaging.

 

The ATXMEGA64A3U-MHR is suitable for industrial control, sensor interfaces, motor control, and USB-enabled embedded applications where mixed-signal processing and low-power operation are required.
