Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'BVXA' against official Infineon documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

Application Specific Microcontrollers Selection Notes

Select this model when automotive qualification and four-port SuperSpeed connectivity are required. Ensure system power design accommodates the 1.2 V core voltage and peak current demands. Verify compatibility with host controllers and target peripherals regarding USB 3.0 protocol support and pin-strapping configurations.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB HX3 family of USB hub controllers. The HX3 series provides USB-IF certified solutions for creating USB hubs on embedded platforms. The CYUSB3304 variant specifically offers four downstream ports, distinguishing it from two-port alternatives within the same product line.

Application Specific Microcontrollers Replacement Considerations

For direct replacements, consider other members of the EZ-USB HX3 family such as the CYUSB3302 for two-port applications. Verify that any substitute maintains the same BGA-100 package and automotive temperature rating.
