Procurement Notes

Verify the exact suffix 'CFXUMA1' against official Infineon documentation to confirm tape-and-reel packaging specifications. Confirm end-of-life status and availability through authorized distributors. Ensure RoHS compliance matches current regulatory requirements for your region before finalizing procurement plans.

Selection Notes

Select this component when a 16-bit architecture with high instruction throughput is required. Consider the specific memory configuration of ROM versus OTP based on production volume needs. Evaluate the peripheral set, particularly the ADC and CAPCOM channels, against application signal processing demands.

Part Context

This part is a derivative within the C166 family, designed for cost-sensitive applications requiring robust performance. It combines the C164 core with enhanced I/O capabilities and flexible memory options. The family is known for supporting high-level languages and operating systems through specific instruction sets.

Replacement Considerations

Check for direct pin-compatible upgrades within the C164CI series. Verify if newer generations like the XC16x offer backward compatibility. Consult Infineon for obsolete part substitution guides if this model is discontinued.
