Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm RoHS compliance and package integrity upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage during soldering processes.

Selection Notes

Select this model for designs requiring robust analog conversion and cryptographic security within the XMEGA A1 family. Consider the specific pinout and package constraints of the 100-lead BGA variant. Evaluate power consumption profiles against the available sleep modes for battery-operated implementations.

Part Context

This component belongs to the AVR XMEGA A1 series, designed for high-performance embedded applications. It utilizes Atmel's high-density nonvolatile memory technology. The series emphasizes low power consumption while delivering processing speeds approaching one MIPS per MHz.

Replacement Considerations

Microchip recommends using the XMEGA A1U series for new designs instead of the A1 series. Verify pin compatibility and peripheral availability when migrating to alternative part numbers within the same manufacturer portfolio.
