Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the unit utilizes a 100-ball BGA format. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Cross-reference ordering codes with official Infineon documentation to validate specific suffix designations.

Application Specific Microcontrollers Selection Notes

Select this model when a four-port USB 3.0 solution is required for commercial-grade environments. Verify that the application does not demand industrial temperature ranges (-40°C to +85°C), which necessitates alternative packaging options. Ensure the system design accommodates the necessary external precision resistors for PHY termination and current reference generation.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB HX3 family of USB 3.2 Gen 1 hub controllers. The family includes variants with two, four, six, or eight ports, offering different combinations of SuperSpeed and USB 2.0 connectivity. The CYUSB3304 specifically provides four standard USB 3.0 downstream ports without shared link capabilities, distinguishing it from the CYUSB332x series.
