Procurement Notes
Verify the specific ordering suffix against official Infineon documentation to confirm pinout compatibility and electrical characteristics. Confirm that the ROMless variant meets the application's memory requirements without external code storage. Ensure the MQFP-100 package dimensions align with the target PCB layout constraints. Check for any specific handling instructions related to moisture sensitivity levels during assembly.
Selection Notes
Select this component when a C166-based architecture is required for legacy or specific automotive standards. The ROMless configuration necessitates external memory if larger code storage is needed. Evaluate the 20 MHz speed limit against real-time processing demands. Consider the 100-pin count for sufficient I/O expansion in complex control loops.
Part Context
This part belongs to the Infineon C165 series, which extends the C166 family. These microcontrollers are widely used in automotive electronics due to their reliability and performance. The C165 series typically offers various memory configurations and package options to suit different system complexity levels.
Replacement Considerations
Consult official Infineon cross-reference guides for verified substitutes. Ensure any replacement maintains C166 compatibility and similar I/O counts.
