Procurement Notes

Verify component authenticity through authorized distributors as this part may be end-of-life. Confirm exact operating temperature grade and memory configuration against official datasheets before procurement. Ensure compatibility with existing MQFP-144 footprints and voltage requirements during sourcing.

Selection Notes

Select this component when a 16-bit C166 architecture is required for automotive or industrial environments. Consider pin count and peripheral availability relative to design constraints. Verify thermal performance specifications against intended operating conditions and ensure supply chain availability for long-term production needs.

Part Context

This microcontroller belongs to the C166 family, widely used in automotive electronics. It shares architectural similarities with XC27x7X series devices but offers lower performance levels suitable for legacy or specific control tasks. The C167 variant typically targets cost-sensitive applications requiring robust 16-bit processing capabilities.

Replacement Considerations

Consult official replacement lists for obsolete parts. Potential alternatives include other C166 family members or newer XC27x series devices if higher performance is acceptable. Verify pinout and peripheral compatibility before substitution.
