CYUSB3328-BVXC

Application Specific Microcontrollers Overview

The CYUSB3328-BVXC is a USB 3.2 Gen 1 hub controller from the EZ-USB™ HX3 family, compliant with USB 3.0 specification revision 1.0. It features eight downstream ports: four SuperSpeed (SS) and four standard USB 2.0 ports. The device supports data rates up to 5 Gbps on all ports and includes an integrated ARM Cortex-M0 CPU with 16 KB RAM and 32 KB ROM. Key proprietary features include shared link capability for embedded applications and ghost charging functionality. The component operates within an industrial temperature range of -40°C to +85°C and utilizes a 100-ball BGA package.

Application Specific Microcontrollers Feature Summary

• Eight Downstream Ports: Supports four SS ports and four USB 2.0 ports simultaneously.
• Shared Link Technology: Enables splitting one SS port into an embedded SS connection and a removable USB 2.0 port.
• Ghost Charging: Emulates a dedicated charging port when the upstream host is disconnected.
• Integrated Processor: Includes an ARM Cortex-M0 CPU for system configuration and battery charging control.

Application Specific Microcontrollers Applications

• Standalone hubs
• PC and tablet motherboards
• Docking stations
• Hand-held cradles

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Confirm that the 100-ball BGA package aligns with PCB layout requirements. Ensure compliance with RoHS standards as indicated in the datasheet specifications.

Application Specific Microcontrollers Selection Notes

Select this model when eight downstream connections are required, specifically combining SuperSpeed and USB 2.0 interfaces. The shared link feature is suitable for embedded designs needing flexible port allocation. Verify power supply constraints, as the industrial grade BGA package has limited active power dissipation capabilities compared to other variants.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-USB™ HX3 product family, which provides USB 3.2 Gen 1 hub solutions. The CYUSB3328 variant is distinguished by its eight-port configuration, offering more connectivity than the four-port CYUSB3324 or six-port CYUSB3326 models within the same series.

Application Specific Microcontrollers Replacement Considerations

CYUSB3326-BVXC offers six ports (two SS, two shared, two USB 2.0). CYUSB3324-BVXC provides four SS ports. Both share the same BGA package but differ in port count and shared link availability.
