ATXMEGA64A4U-AUK

Overview

The ATXMEGA64A4U-AUK is an 8/16-bit microcontroller from the AVR XMEGA A4U family, manufactured by Microchip Technology. It features a 64KB in-system self-programmable flash memory, 2KB EEPROM, and 4KB internal SRAM. The device operates on a supply voltage range of 1.6V to 3.6V with a maximum clock frequency of 32MHz. It includes a four-channel DMA controller, an eight-channel event system, five 16-bit timer/counters, one USB 2.0 full-speed interface, five USARTs, two TWIs, and two SPIs. The component utilizes a 44-lead TQFP package.

Feature Summary

Integrates a high-performance AVR CPU executing instructions in a single clock cycle for optimized power consumption versus processing speed.
Includes a four-channel DMA controller and an eight-channel event system for efficient data transfer and peripheral communication.
Features a 12-channel, 12-bit Analog-to-Digital Converter (ADC) and a two-channel, 12-bit Digital-to-Analog Converter (DAC).
Supports capacitive touch sensing via the QTouch library for buttons, sliders, and wheels.

Applications

Industrial control systems
Climate control units
Low power battery applications
Factory automation
USB connectivity devices

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with required programming interfaces such as PDI. Confirm RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this model when 64KB program memory and 34 programmable I/O pins are required within a compact footprint. Consider the integrated USB interface and crypto engine for secure communication needs. Evaluate the 1.6V to 3.6V operating range against system power constraints.

Part Context

This component belongs to the AVR XMEGA A4U series, designed for low-power, high-performance embedded applications. It shares architectural similarities with other members like the ATXMEGA32A4U and ATXMEGA128A4U, differing primarily in memory sizes and pin counts.
