• Body electronics systems
• Industrial motor control applications

Procurement Notes

Verify the exact suffix against official Infineon documentation, as variations like 'CA' versus 'CX' may indicate different packaging or qualification statuses. Confirm availability status as many C16xx components are discontinued. Ensure compatibility with existing PCB footprints for the 100-pin MQFP package during procurement planning.

Selection Notes

Select this component when a 16-bit automotive-grade MCU with specific I/O counts and analog capabilities is required. Compare against other C161 variants based on package type and voltage range. Verify that the 20MHz clock speed meets real-time processing requirements for the target application.

Part Context

This part belongs to the Infineon C166 family, widely used in automotive embedded systems. It serves as a successor to earlier 166 architectures while maintaining backward compatibility. The C161 sub-series typically targets cost-sensitive applications requiring robust peripheral integration without on-chip program memory.
