Product details
Overview
CYUSB3302-BVXC from Infineon is a USB 3.2 Gen 1 (5 Gbps) hub controller with two downstream USB 3.0 ports, integrated ARM® Cortex®-M0 CPU (16 KB RAM, 32 KB ROM), USB Battery Charging v1.2 compliance, and support for shared-link mode in embedded systems. It integrates SS and USB 2.0 PHYs, four transaction translators, and on-chip termination resistors to reduce BOM count.
For engineers reviewing the CYUSB3302-BVXC datasheet, CYUSB3302-BVXC pinout, CYUSB3302-BVXC application, or CYUSB3302-BVXC equivalent, this device serves as a certified, configurable hub IC for docking stations, embedded motherboards, and industrial USB expansion where BC v1.2 charging, ghost charging, and firmware-upgradable I2C bridge functionality are required.
Technical Context
The CYUSB3302-BVXC implements dual 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 Multi-TT architecture, L0–L3 power management, and suspend/resume signaling. It embeds an ARM Cortex-M0 subsystem for real-time configuration, battery charging control, and vendor-command execution.
Its port controller manages external power switches with ganged enable mode, overcurrent detection, and LED indicators per port; configuration is supported via pin-straps (not applicable to CYUSB3302), I2C EEPROM, or eFuse - though CYUSB3302-BVXC uses fixed pin-strap configuration per datasheet Table 1 and supports only 68-pin QFN and 100-ball BGA packages.

Key Features
| Feature | Design Value |
|---|---|
| Integrated ARM Cortex-M0 | Enables runtime reconfiguration of GPIOs, overcurrent response, and custom charging profiles without external MCU |
| Ghost Charging | Allows DS ports to emulate Dedicated Charging Ports (DCP) when upstream host is disconnected-enabling battery top-up in docked/embedded standby |
| USB-to-I2C Bridge | Vendor-command interface permits firmware updates of external ASSPs or ISP of connected EEPROM via USB, eliminating separate programming hardware |
| Shared Link Mode | Not supported on CYUSB3302; reserved for higher-port-count variants (CYUSB3326/CYUSB3328) |
| Pin-strap Configuration | Fixed at factory for CYUSB3302-BVXC; eliminates external strapping resistors and simplifies layout vs. configurable variants |
Applications
| Standalone USB Hub | Docking Station |
|---|---|
Use Scenario: Compact desktop or travel hub expanding one USB-C/Type-A upstream port into two downstream USB 3.0 ports. IC Role / Device Role / Timing Role: Central hub controller managing SS/USB 2.0 protocol translation, power switching, and BC v1.2 charging negotiation. Use Value: Eliminates need for discrete USB 2.0 TT and SS repeater ICs; reduces component count by integrating PHYs, termination, and M0-based control logic. | Use Scenario: Multi-interface docking station connecting laptop to monitor, storage, peripherals, and smartphone simultaneously. IC Role / Device Role / Timing Role: Downstream hub controller handling concurrent high-bandwidth display data (via USB 3.0) and BC v1.2 charging for attached mobile devices. Use Value: Ghost charging maintains smartphone battery level during laptop sleep; ACA-Dock support not applicable to CYUSB3302 but BC v1.2 ensures Apple-compatible charging on both DS ports. |
| Embedded Motherboard | Industrial Printer |
Use Scenario: Embedded system motherboard requiring two fixed USB 3.0 ports for internal SSD and external peripheral connectivity. IC Role / Device Role / Timing Role: Integrated hub controller providing deterministic USB enumeration, low-latency interrupt handling via Cortex-M0, and robust ESD protection per port. Use Value: Pin-strapped configuration ensures repeatable boot behavior; industrial temp rating (–40°C to +85°C) guarantees reliability in fanless enclosures. | Use Scenario: Networked industrial printer with USB host interface for flash drive firmware updates and direct print jobs. IC Role / Device Role / Timing Role: USB hub managing simultaneous connection of USB storage (for firmware) and barcode scanner (for job control), with overcurrent protection per port. Use Value: Integrated power switch control and OVR signal prevent bus lockups during hot-plug events; WHQL certification ensures plug-and-play compatibility with Windows-based print servers. |
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 |
|---|---|---|---|
| CYUSB3304-BVXC | 4-port USB 3.0 hub; identical feature set including BC v1.2, Cortex-M0, and I2C bridge; larger 88-pin QFN or 100-ball BGA package | Supports higher peripheral density; suitable for docking stations requiring ≥3 downstream ports | Select when system requires >2 DS ports and board space allows larger package or BGA assembly |
| UPD720210K8-711-BAC-A | Renesas 4-port USB 3.0 hub; no embedded CPU; no ghost charging; supports USB 2.0 LPM but lacks BC v1.2 compliance | Limited to basic hub functions; no firmware upgradability or smart charging features | Choose for cost-sensitive, non-charging applications where external MCU handles charging logic |
Compared with CYUSB3304-BVXC, CYUSB3302-BVXC offers identical firmware and feature parity in a smaller 68-pin QFN footprint-ideal for space-constrained designs. Versus UPD720210, it delivers integrated charging intelligence and field-upgradable behavior via its Cortex-M0, reducing system-level BOM and software complexity.

FAQ
Does CYUSB3302-BVXC support USB 3.2 Gen 2 (10 Gbps)?
No. CYUSB3302-BVXC is compliant with USB 3.2 Gen 1 (5 Gbps) and fully backward-compatible with USB 2.0 High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps). It does not implement the Gen 2 superspeed transmitter/receiver architecture or associated 10 Gbps PHY layers.
Can the embedded Cortex-M0 be used to run custom application firmware?
Yes. The ARM Cortex-M0 subsystem includes 16 KB of on-chip RAM and 32 KB of ROM, and supports firmware loading from I2C EEPROM or external I2C master. Infineon's Blaster Plus tool enables customization of GPIO behavior, charging profiles, and vendor-command responses without modifying silicon.
Is shared link mode available on CYUSB3302-BVXC?
No. Shared link mode-allowing simultaneous SS and USB 2.0 connections per downstream port-is implemented only in CYUSB3326 and CYUSB3328 variants per datasheet Table 1. CYUSB3302-BVXC supports standard single-link downstream ports with full USB 3.0 and USB 2.0 coexistence per port.
What configuration methods are supported for CYUSB3302-BVXC?
CYUSB3302-BVXC supports I2C-based configuration (slave mode for EEPROM boot, master mode for ISP) and eFuse programming. Unlike CYUSB3304/CYUSB3314, it does not support pin-strap configuration-the VID, PID, and port enable settings are factory-programmed and fixed.
