ATXMEGA128D3-MH: A Comprehensive Microchip Microcontroller Solution

The ATXMEGA128D3-MH from Microchip Technology stands as a powerful and versatile 8/16-bit microcontroller, engineered to deliver exceptional performance and low power consumption for a wide array of embedded applications. As a key member of the high-performance AVR® XMEGA® family, this device integrates a rich set of advanced peripherals, making it an ideal single-chip solution for complex designs in industries such as industrial automation, consumer electronics, and IoT.

Built on the proven AVR enhanced RISC architecture, the core achieves up to 32 MIPS performance at 32 MHz, enabling it to handle computationally intensive tasks with ease. The 128KB of in-system self-programmable Flash and 8KB of SRAM provide ample space for sophisticated application code and data handling. A standout feature is its DMA Controller (Direct Memory Access), which allows data to be transferred between peripherals and memory without CPU intervention. This significantly reduces processor overhead, maximizing system efficiency and enabling truly low-power operation.

The peripheral set of the ATXMEGA128D3-MH is exceptionally comprehensive. It includes a 16-channel Event System that allows peripherals to communicate directly with each other, triggering actions independently of the CPU. This is complemented by multiple high-resolution 16-bit timers/counters, a 12-bit, 2Msps Analog-to-Digital Converter (ADC) with up to 12 channels, and two 12-bit Digital-to-Analog Converters (DACs), providing superior analog capabilities for precision sensing and control. For communication, it is equipped with multiple USARTs, SPI, and I²C interfaces, facilitating seamless connectivity with other system components.

Housed in a compact 64-pad QFN (MLF) package, the ATXMEGA128D3-MH is designed for space-constrained applications without compromising on functionality. Its advanced power management features, including multiple sleep modes and a real-time clock, ensure that it excels in battery-powered and energy-harvesting applications where power efficiency is paramount.

ICGOODFIND: The ATXMEGA128D3-MH is a highly integrated and capable microcontroller that successfully balances raw processing power, advanced peripheral integration, and outstanding energy efficiency, making it a top-tier choice for developers designing next-generation embedded systems.
