Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct memory configuration and package variant. Confirm that the component meets the required automotive or industrial qualification standards for your specific design implementation before finalizing procurement.

Selection Notes

Select this MCU when a 16-bit C166 core is required with 64 KB OTP/ROM and 4 KB RAM. Ensure the design accommodates the MQFP-80 surface mount package and 5V logic levels. Verify compatibility with existing 8-bit peripheral interfaces if migrating from older Infineon architectures.

Part Context

This part belongs to the Infineon C164CI family of 16-bit microcontrollers. These devices are designed for high-reliability applications in automotive and industrial sectors. The C164CI series offers enhanced performance over previous 8-bit generations while maintaining backward compatibility for legacy system integration.

Replacement Considerations

Check for C164CI variants with different memory sizes or package options. Verify if newer Infineon 16-bit or 32-bit MCUs offer pin-compatible alternatives for long-term supply assurance.
