概要
Description
CYUSB3314-88LTXC is Cypress’s USB 3.0 hub controller IC. It implements a USB hub function (upstream host port plus multiple downstream ports) with an integrated SuperSpeed PHY and hub logic, enabling embedded designs to provide USB 3.0 connectivity to peripherals. Typical capabilities include 5 Gbps USB 3.0 support with USB 2.0 compatibility, per-port power switching and protection, a vendor/configuration interface for managing the hub, and power-management features. It targets external USB hubs, docking stations, and other embedded applications needing a compact, single-chip hub solution. The “88LTXC” suffix relates to the package/temperature/trace options and packaging. For exact port count, electrical specs, package details, and programming interface, consult the CYUSB3314 datasheet and evaluation-board documentation.
