Product Overview
The VL716-Q4 is a single-chip USB 3.1 Gen 2 to SATA 6Gbps bridge controller by VIA Labs (VLI). Optimized for external storage, it delivers up to 10Gbps USB speeds and connects directly to SATA Gen3 SSDs/HDDs. Its integrated USB Type-C multiplexer and CC logic support native reversible plug operation without an external switch chip. It supports both BOT and UASP protocols to reduce CPU overhead and boost throughput. Packaged in a compact, low-power QFN-48 (6x6x0.4mm), it is ideal for drive enclosures, portable backup drives, docking stations, and embedded storage bridges.
Core Advantages
Ultra-Fast USB 3.1 Gen 2 10Gbps Bandwidth
Delivers true 10Gbps data throughput pipelines, maximizing the hidden hardware read/write velocity limits of modern solid-state drives without creating host-side interface bottlenecks.
Integrated USB Type-C Functionality
Houses a native USB Type-C CC controller and multiplexer matrix directly inside the silicon, minimizing the physical footprint, bill-of-materials cost, and layout complexity for modern reversible connectors.
UASP and BOT Protocol Acceleration
Supports both traditional BOT and high-speed USB Attached SCSI Protocol (UASP) acceleration mechanisms, driving down CPU utilization while boosting random file chunk transfers significantly.
Built-In Low-Power Switching Power Supply
Integrates on-chip DC-DC switching regulators to step down voltage internally, dramatically minimizing standby power loss and simplifying power-rail decoupling routing on crowded target PCBs.

Frequently Asked Questions
Q1: Is your stock inventory of the VL716-Q4 completely authentic and factory-new?
A: Yes, we guarantee that all VL716-Q4 bridge controllers in our current inventory are 100% brand-new, original factory components from VIA Labs, Inc., handled and stored under strict anti-static ESD shielding and dry-pack moisture-control standards.
Q2: What is decoded by the specific “-Q4” suffix in the part identification layout?
A: The “Q4” designation defines the specific physical package layout and pins format. It indicates that the chip is housed in the ultra-compact QFN-48 (6x6x0.4mm) footprint configuration with standard commercial thermal ratings.
Q3: Does the VL716-Q4 require an external crystal or separate multiplexer chip to operate a Type-C connector?
A: No, the VL716-Q4 features fully integrated Configuration Channel (CC) logic and an internal high-speed data mux. It handles Type-C cable flippability natively, which saves critical circuit board space and eliminates the cost of external switching silicon components.
Q4: How can our engineering group download reference schematic layout files, firmware update binaries, or bulk quote structures?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
