Overview

The CYUSB3326-BVXC is a highly integrated USB 3.2 Gen 1 (5 Gbps) hub controller from the Infineon HX3 family. It features an on-chip ARM Cortex-M0 processor and 32kB of ROM to manage complex power delivery and battery charging protocols across its 4 downstream ports. This controller is designed for high-performance connectivity in docking stations, monitors, and portable hubs.

Why Choose This Part

The HX3 architecture provides a shared-link PHY for optimized power consumption, drawing approximately 720mW during operation. The inclusion of an ARM Cortex-M0 allows for flexible port configuration and status monitoring via I2C. Its small 6mm width VFBGA package is ideal for space-constrained PCB designs that require full USB 3.0 performance.

Applications

USB Docking Stations
Provides high-speed 5 Gbps data throughput for multiple peripherals in desktop and mobile docking solutions.
Integrated Monitor Hubs
Embedded within display panels to provide user-accessible SuperSpeed USB ports.
Industrial PC Connectivity
Used in ruggedized computing environments to expand SuperSpeed I/O in a compact 100-VFBGA footprint.
Battery Charging Hubs
Leverages HX3 charging support (BC 1.2) to provide high-current power delivery to downstream mobile devices.

Getting Started

Designers should utilize the HX3 Configuration Utility to program port settings and battery charging parameters. Development can be accelerated using the CY4503 EZ-USB HX3 Reference Design Kit. Ensure the PCB layout follows strict impedance matching for the 5 Gbps differential pairs and provides stable 1.2V and 3.3V supply rails.
