Procurement Notes

This component is classified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or legacy stock. Verify the specific ordering suffix and package variant against current inventory lists before procurement planning. Ensure compatibility with existing board layouts due to the MQFP-144 footprint.

Selection Notes

Select this part only if legacy C166 architecture compatibility is required for existing designs. Consider the limited availability and obsolete status when planning long-term production. Evaluate alternative modern microcontrollers if new development is underway, as support and supply chain stability may be compromised for this specific model.

Part Context

The C167 series belongs to Infineon's C166 family of 16-bit microcontrollers, widely used in automotive and industrial applications. This specific model represents a ROMless variant, necessitating external code memory. The C167 line provides high-performance processing with integrated peripherals for complex control tasks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements are not explicitly listed. Engineering teams should consult official replacement guides or contact the manufacturer for validated cross-reference options.
