ATXMEGA64C3-AU

Overview

The ATXMEGA64C3-AU is an 8/16-bit microcontroller based on the AVR XMEGA C3 family. It features 64KB of in-system self-programmable flash, 2KB EEPROM, and 4KB internal SRAM. The device operates at frequencies up to 32MHz with a supply voltage range of 1.6V to 3.6V. Key peripherals include a USB 2.0 full-speed interface, three USARTs, two TWIs, two SPIs, five 16-bit timer/counters, a sixteen-channel 12-bit ADC, and two analog comparators. It utilizes a 64-lead TQFP package.

Feature Summary

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct memory size and package type. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Check for any recent product change notices regarding assembly or labeling updates before finalizing procurement plans.

Selection Notes

Select this model when a balance of processing speed and low power consumption is required for embedded designs. The integrated USB interface makes it suitable for direct host communication without external transceivers. Consider the available I/O count and peripheral set relative to the system complexity to ensure adequate resource allocation.

Part Context

This component belongs to the Atmel AVR XMEGA C3 series, designed for high-performance, low-power applications. The series combines an 8/16-bit RISC CPU with rich peripheral sets and nonvolatile memory technologies. It targets markets requiring efficient code execution and flexible connectivity options within compact packages.

Replacement Considerations

The ATXMEGA64C3-AUR serves as the tape and reel variant of this component. Other members of the XMEGA C3 family offer different memory capacities but share similar architectural features.
