Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '40LQXI' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure that the required firmware development tools, such as the EZ-PD CCG3 SDK, are compatible with the selected hardware revision before procurement.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring a dedicated USB-C port controller with embedded flash memory for firmware storage. The wide input voltage range (up to 21.5 V) allows direct connection to higher voltage bus lines without external level shifting. Confirm that the QFN-40 package fits the PCB footprint constraints and thermal requirements of the target enclosure.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD CCG3 series, which utilizes Cypress's proprietary M0WS8 technology. The CCG3 family is optimized for cost-sensitive USB-C implementations where integrated flash reduces bill-of-materials complexity compared to controllers requiring external memory.

Application Specific Microcontrollers Replacement Considerations

The CYPD3122-40LQXIT is a related variant within the same CCG3 family but features a DFP (Downstream Facing Port) configuration instead of UFP. Verify pin compatibility and functional requirements when considering cross-model substitution.
