Procurement Notes

Verify current availability status as this part number is listed as obsolete. Confirm that the 80-pin P-MQFP package dimensions match your PCB footprint requirements. Ensure compatibility with existing firmware development tools for the C166 architecture before procurement planning.

Selection Notes

Select this component only if legacy C166 software support is required or if specific pinout constraints necessitate the 80-pin form factor. Evaluate the 20 MHz performance limit against system timing requirements. Consider the ROMless nature when designing memory mapping schemes.

Part Context

This model belongs to the Infineon C161K series of 16-bit microcontrollers. These devices are designed for high-performance embedded applications requiring robust processing capabilities within automotive and industrial environments. The series emphasizes reliability and extensive peripheral integration.

Replacement Considerations

Public confirmed substitute: XMC4200F64K256BAXQSA1. Verify architectural differences between the legacy C166 core and modern XMC families during migration.
