Product details
Overview
CYUSB3304-BVXC from Infineon is a USB 3.2 Gen 1 (5 Gbps) hub controller with four downstream ports, integrated ARM® Cortex®-M0 CPU (16 KB RAM, 32 KB ROM), USB Battery Charging v1.2 compliance per port, shared-link capability for embedded dual-device attachment per port, and industrial temperature range (–40°C to +85°C). It enables compact docking stations requiring simultaneous high-speed data and BC v1.2 charging.
For engineers reviewing the CYUSB3304-BVXC datasheet, CYUSB3304-BVXC pinout, CYUSB3304-BVXC application, or CYUSB3304-BVXC equivalent, key selection criteria include SS/USB 2.0 dual PHY support, ghost charging behavior, I2C-based firmware upgrade path, and pin-strapped configuration of VID/PID, port count, and power switch ganging mode.
Technical Context
The device integrates two independent hub controllers: a SuperSpeed (SS) hub supporting U0–U3 link power states and full-duplex 5 Gbps operation, and a USB 2.0 hub with four dedicated transaction translators (Multi-TT), L0–L3 power management, and suspend/resume signaling. Both controllers route through a unified port controller block managing VBUS, overcurrent detection, and LED indicators.
Its embedded ARM® Cortex®-M0 subsystem handles runtime configuration, battery charging state machines, vendor-command execution (e.g., USB-to-I2C bridge), and shared-link arbitration logic-enabling each DS port to concurrently serve one SS device and one USB 2.0 device without external multiplexing.
Key Specifications

| SSTxP/Mx/SSRxP/Mx (x=1–4) | SuperSpeed differential transmit/receive pair | Terminated 100 Ω differential interface for 5 Gbps operation; requires controlled impedance routing |
| VBUSx_DET | Downstream VBUS presence detection | Monitors +5 V on each DS port to enable/disable charging and port enumeration logic |
| PWR_ENx | External power switch enable | Active-high control signal for discrete load switches; supports ganged or individual port power sequencing |
| I2C_DATA / I2C_CLK | Bi-directional I2C bus interface | Configures device at boot or runtime; supports EEPROM programming and USB-to-I2C bridging |
| RESET_N | Asynchronous active-low reset input | Resets internal state machines, CPU, and PHYs; requires ≥10 µs pulse width |
Key Features
| Feature | Design Value |
|---|---|
| Shared Link Mode | Each DS port simultaneously connects one SS device and one USB 2.0 device - eliminates need for external muxes in embedded host designs |
| Ghost Charging | DS ports emulate DCP when upstream host is disconnected - delivers up to 1.5 A per port without host negotiation |
| Vendor Command Support | USB-class vendor requests implement I2C master functionality - enables firmware update of external ASSPs via USB without additional MCU |
| Pin-Strap Configuration | Hardware-selectable VID/PID, port count, BC v1.2 enable, and power switch ganging - reduces reliance on external EEPROM in cost-sensitive designs |
| WHQL Certification | Microsoft Windows XP/Vista/7/8/8.1 certified driver - eliminates custom driver development for PC-attached applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 3.0 hub controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYUSB3314-BVXC | 88-pin QFN only; adds pin-strap support and port indicators; same 4-port SS/USB 2.0 architecture | Preferred where LED status feedback and flexible hardware configuration are required | Select when board layout accommodates larger QFN and visual port status is needed |
| UPD720210K8-701-BAC-A | Renesas USB 3.0 hub; no embedded CPU; no ghost charging or shared-link; requires external EEPROM for VID/PID | Suitable for basic hub functions without advanced charging or firmware extensibility | Choose for cost-sensitive, non-embedded applications where Infineon's M0 subsystem and BC v1.2 features are unnecessary |
Compared with CYUSB3304-BVXC, CYUSB3314-BVXC offers enhanced configurability and diagnostics but lacks BGA packaging; UPD720210K8-701-BAC-A provides simpler implementation but omits embedded intelligence, ghost charging, and shared-link-making it unsuitable for host-less charging or dual-protocol embedded ports.

FAQ
Does CYUSB3304-BVXC support USB 3.2 Gen 2 (10 Gbps)?
No. CYUSB3304-BVXC complies strictly with USB 3.2 Gen 1 (5 Gbps) and USB 3.0 specification revision 1.0. It does not support 10 Gbps signaling, Gen 2x2 modes, or USB4 tunneling. Its SS PHY is rated for 5 Gbps operation only, with full backward compatibility to USB 2.0 High-Speed (480 Mbps).
Can the embedded Cortex®-M0 be used for custom application code?
No. The ARM® Cortex®-M0 is reserved for Infineon's proprietary firmware controlling hub operation, charging logic, and vendor commands. It is not user-programmable; no SDK, debug interface, or flash memory is exposed for third-party code execution.
What is the function of the "shared link" feature?
Shared link allows a single downstream port to simultaneously connect one SuperSpeed (5 Gbps) device and one USB 2.0 (480 Mbps) device using separate differential pairs. This eliminates external multiplexers in embedded systems where both protocol types must coexist on one physical connector-e.g., a USB-C port hosting a camera and keyboard.
Is external EEPROM required for basic operation?
No. CYUSB3304-BVXC supports pin-strapped configuration for VID/PID, port count, and charging enablement-enabling full functionality without EEPROM. I2C EEPROM is optional for dynamic reconfiguration or storing custom string descriptors; the device boots from internal ROM with factory defaults.
