Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm specific suffix variations against official datasheets as they may indicate different memory configurations or temperature grades. Request full traceability documentation for critical automotive deployments. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Evaluate memory requirements against available ROM or ROMless variants within the C167CSL series. Compare peripheral counts and clock speeds with newer XC2000 or XMC families if future scalability is needed. Assess pinout compatibility with legacy designs when considering migration paths. Verify voltage supply specifications and operating temperature ranges match the target application environment constraints.

Part Context

This component belongs to the established C166 microcontroller lineage, widely utilized in automotive powertrain systems. It represents a mature technology platform offering proven reliability and extensive software support ecosystems. While newer architectures exist, this part remains relevant for cost-sensitive designs requiring robust 16-bit processing capabilities without the complexity of modern multi-core solutions.

Replacement Considerations

Official substitutes include the XC27x7X series for enhanced performance or the XMC4700 series for ARM-based upgrades. Cross-reference pinouts and peripheral mappings carefully during migration. Consult Infineon's lifecycle notices for end-of-life timelines and recommended transition strategies.
