Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package and tape/reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the part number with official Infineon documentation to validate availability and production status.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring integrated USB-C PD controller functionality with substantial onboard memory for custom firmware. The wide input voltage range suits applications powered directly from VBUS or external supplies up to 21.5 V. Ensure the design accommodates the 40-pin QFN thermal pad requirements and industrial temperature constraints.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD CCG3 Flash series, designed for flexible USB Type-C port control. It differs from non-flash variants by offering extensive programmable memory for complex power delivery profiles and proprietary protocols. The CCG3 family targets high-performance USB-C applications requiring robust firmware capabilities.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include other CYPD3120 variants with different suffixes indicating package or reel differences. For functional equivalents with different memory configurations, consider other CCG3 models. Verify pin compatibility and firmware compatibility when substituting.
