Procurement Notes

This component is officially discontinued and no longer manufactured by Infineon Technologies. Availability is strictly limited to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing replacements. Confirm that any substitute components meet the original electrical specifications and pinout requirements to ensure system compatibility.

Selection Notes

Select this component only if legacy C166 architecture compatibility is required. Consider modern alternatives like the XC2000 series for new designs due to discontinued status. Evaluate pin compatibility and software migration efforts before transitioning to newer microcontroller families. Ensure replacement parts match the specific MQFP-144 footprint and thermal characteristics.

Part Context

Part of the C16xx family based on the mature C166 core architecture. Designed for high-performance embedded applications requiring robust real-time processing capabilities. The C167 variant typically offers enhanced peripheral integration compared to base models. This specific suffix indicates tape and reel packaging for automated assembly processes.
