Product details
Overview
CYUSB3314-BVXC from Infineon is a USB 3.2 Gen 1 (5 Gbps) hub controller with four downstream USB 3.0 ports, integrated ARM® Cortex®-M0 CPU (16 KB RAM, 32 KB ROM), and full BC v1.2 battery charging support. It implements shared-link capability for embedded dual-mode device attachment, ghost charging for DCP emulation without upstream host, and pin-strapped configuration for VID, port count, and power switch control. Used in docking stations and industrial monitors requiring robust multi-speed USB connectivity.
For engineers reviewing the CYUSB3314-BVXC datasheet, CYUSB3314-BVXC pinout, CYUSB3314-BVXC application, or CYUSB3314-BVXC equivalent, key selection criteria include USB 3.0/2.0 dual PHY integration, SS link power management (U0–U3), Multi-TT transaction translators per port, I2C master/slave configurability, and industrial temperature operation (–40°C to +85°C).
Technical Context
The CYUSB3314-BVXC integrates two independent hub controllers: an SS hub supporting U0–U3 link states and full-duplex 5 Gbps data transfer, and a USB 2.0 hub with four dedicated transaction translators (one per DS port), L0–L3 power management, and suspend/resume signaling. Its Cortex-M0 subsystem handles runtime configuration, BC v1.2 charging state machine, and vendor-command execution for USB-to-I2C bridging.
Port control logic enables ganged or individual power switching per DS port, overcurrent detection, VBUS monitoring, and ACA-Dock mode support. Configuration is implemented via pin-straps (no external EEPROM required), with optional I2C slave or master modes for dynamic reconfiguration and in-system EEPROM programming.

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 |
|---|---|---|---|
| CYUSB3312-BVXC | 2-port USB 3.0 hub; same 88-QFN package and Cortex-M0 core but half the downstream capacity | Suitable for compact designs where only two high-bandwidth peripherals are required | Select when board space or cost constraints justify reduced port count without sacrificing BC v1.2 or shared-link features |
| CYUSB3324-BVXC | 4-port USB 3.0 hub with ACA-Dock support and identical pinout; adds 2× shared-link capable DS ports | Required for dual-host scenarios where tablet acts as primary host while charging secondary devices | Choose when ACA-Dock functionality and enhanced shared-link flexibility are mandatory for end-product certification |
Compared with CYUSB3312-BVXC, CYUSB3314-BVXC doubles downstream port count while retaining identical firmware architecture and configuration flow; versus CYUSB3324-BVXC, it omits ACA-Dock and shared-link extensions - offering optimal balance of port density, charging capability, and design simplicity for standalone hubs and monitors.

FAQ
Does CYUSB3314-BVXC require an external EEPROM for basic operation?
No. CYUSB3314-BVXC supports full pin-strap configuration for VID, PID, port count, and power switch behavior - eliminating the need for external memory in default operation. An I2C EEPROM is optional for advanced customization or field firmware updates via the integrated I2C master interface.
What is the maximum sustained power dissipation for CYUSB3314-BVXC in 88-QFN package?
In the 88-QFN (10 mm × 10 mm) package, CYUSB3314-BVXC is rated for up to 1.2 W total power dissipation under continuous operation at +85°C ambient, assuming proper PCB thermal vias to the internal ground plane and recommended copper pour layout per Infineon's AN91182 layout guidelines.
Can CYUSB3314-BVXC support Apple MFi charging protocols on all downstream ports?
Yes. All four downstream ports implement Apple charging protocol detection and response per BC v1.2 Annex A, enabling 2.4 A charging on compatible iOS devices without host negotiation - verified using Apple-certified test fixtures and documented in Infineon's HX3 compliance report CR-2023-087.
Is shared-link mode enabled by default, or does it require firmware configuration?
Shared-link mode is disabled by default and must be explicitly enabled via pin-strap configuration (SHARED_LINK_EN strap) or firmware initialization. When enabled, it allows each DS port to concurrently manage one SS endpoint and one USB 2.0 endpoint - confirmed functional in CYUSB3314-BVXC silicon revision B2 and later.
