Procurement Notes

Verify the specific suffix QMA1 against official Infineon documentation to confirm exact manufacturing lot details and regional compliance status. Ensure the selected variant matches the required ROMLess configuration and thermal specifications for the target environment. Cross-reference the datasheet revision date to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a C166-based solution with external memory interface requirements is needed. The ROMLess designation indicates the absence of onboard program memory, necessitating external storage. Verify that the 20 MHz clock speed and 2 kB RAM capacity meet the application's processing demands. Confirm compatibility with the 4.5 V to 5.5 V power supply rails and industrial temperature range requirements.

Part Context

This part belongs to the Infineon C165 family, which extends the C166 architecture for high-performance embedded control. The C165 series typically targets complex control tasks in automotive and industrial sectors. The LFHABXQMA1 suffix denotes specific packaging, temperature grade, and traceability attributes defined by Infineon for this particular unit within the broader product portfolio.

Replacement Considerations
