Présentation
Description
The VL805-Q6 is a PCIe to USB 3.0 controller developed by VIA Labs, designed to add high-speed USB 3.0 ports to systems via a PCI Express interface. It supports four downstream USB 3.0 ports with 5 Gbps transfer speeds (USB 3.2 Gen 1) and is backward compatible with USB 2.0/1.1.
Key features include:
- PCIe 2.0 x1 interface (compatible with x2/x4 slots)
- UASP (USB Attached SCSI Protocol) support for faster data transfers
- Low power consumption and advanced power management
- Plug-and-play compatibility with major operating systems
Commonly used in motherboards, expansion cards, and embedded systems, the VL805-Q6 provides a cost-effective solution for adding USB 3.0 connectivity. It is often compared to ASMedia and Renesas controllers but is favored for its balance of performance and efficiency.
For detailed specifications, refer to VIA Labs' official datasheet.
