Procurement Notes

Verify the specific ordering suffix and package variant against the official Infineon datasheet before procurement. Confirm that the component meets RoHS compliance requirements for your target market. Check the latest lifecycle status to ensure availability until December 2035. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dedicated PLC modem is required alongside significant programmable logic capabilities. The M8C core offers sufficient processing power for protocol handling while the integrated analog blocks reduce external component count. Consider the 48-pin QFN footprint for space-constrained PCB designs requiring high pin density.

Part Context

This part belongs to the CY8CPLC series of programmable system-on-chip devices. It combines microcontroller functionality with specialized power line communication hardware. The series is designed to simplify the integration of PLC capabilities into embedded systems without requiring separate modem chips.

Replacement Considerations

Consult the official Infineon replacement guide for verified cross-references. No direct substitute part numbers are confirmed in the provided public documentation. Verify compatibility of pinouts and software libraries if considering alternative PLC solutions.
