ATXMEGA64A3U-MH Description

Short technical summary and product information.

The ATXMEGA64A3U-MH is an 8/16-bit AVR XMEGA microcontroller from Microchip Technology, featuring a 32MHz AVR core with 64KB of in-system self-programmable Flash memory, 4KB SRAM, and 2KB EEPROM. It operates from 1.6V to 3.6V and is rated for -40°C to +85°C temperature range. The device integrates a rich set of peripherals including a 4-channel DMA controller, 8-channel event system, seven 16-bit timer/counters, a USB 2.0 full-speed device interface, two 12-bit ADCs (16 channels each, 2Msps), one 12-bit DAC (2 channels, 1Msps), four analog comparators, and a crypto engine supporting AES and DES encryption. Connectivity options include I2C, SPI, USART, and USB. The microcontroller is housed in a 64-VFQFN exposed pad package (9x9mm) for surface mount assembly. This combination of features makes it suitable for a wide range of embedded applications requiring low power, high performance, and versatile connectivity.
