Procurement Notes

Verify component authenticity through authorized distributors as this part is marked as obsolete. Confirm package integrity upon receipt, specifically checking for lead coplanarity on the 128-LQFP variant. Ensure handling procedures comply with MSL Level 3 moisture sensitivity requirements. Cross-reference ordering suffixes carefully to match exact pinout and thermal specifications required by your design.

Selection Notes

Select this component when a 16-bit C166 core is required with no onboard flash memory. It is suitable for designs needing significant GPIO count and specific analog input channels. Consider the 25MHz clock limit and commercial temperature range during system planning. Evaluate alternative legacy parts if current production availability is critical for long-term manufacturing.

Part Context

This microcontroller belongs to the established C166 family, widely used in automotive and industrial sectors. It represents a mature technology node focusing on deterministic real-time performance. The C16xx series is known for its efficient instruction set and specialized peripherals for power control. While superseded by newer architectures, it remains relevant for cost-sensitive or legacy-compatible embedded projects.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status of this specific model. Engineers should consult official replacement guides for modern equivalents within the XC166 or Aurix families, ensuring compatibility with existing CANbus and peripheral configurations.
