Procurement Notes
Verify the specific suffix (e.g., UMA1 vs UMA2) against official datasheets to ensure correct package and revision compatibility. Confirm end-of-life status with the manufacturer before finalizing designs. Check moisture sensitivity level handling requirements during storage and assembly processes.
Selection Notes
Select this component when a 16-bit C166 architecture with external memory support is required. Ensure the application utilizes CANbus or standard serial interfaces. Verify that the 4.5V to 5.5V supply range matches the system power rails. Consider the 25MHz speed limit for real-time processing requirements.
Part Context
This part belongs to the Infineon C16xx family of 16-bit microcontrollers designed for high-performance embedded applications. The C161 variant specifically targets cost-sensitive automotive and industrial markets requiring robust peripheral integration and reliable operation under varying environmental conditions.
Replacement Considerations
