Overview

The USB5816C/KD is a high-performance, low-power USB 3.1 Gen 1 hub controller featuring 6 downstream ports. It integrates support for USB Type-C and legacy USB 2.0, providing a flexible solution for high-speed data distribution in complex embedded systems. The controller includes internal ROM for configuration and supports external SPI or I2C interfaces for customized firmware and hardware management.

Why Choose This Part

The USB5816C features FlexConnect technology, which allows for flexible port switching and easy port mapping via SMBus or I2C. It reduces BOM complexity by integrating 8KB of RAM and 64KB of Flash while maintaining a power-efficient profile, consuming approximately 792mA at 1.2V during full SuperSpeed operation across five ports.

Applications

Laptop Docking Stations
Provides multiple USB 3.1 and Type-C downstream ports for peripheral expansion from a single host connection.
Industrial PC Motherboards
Integrates high-speed connectivity directly onto the PCB with a small 100-VQFN footprint.
Monitor Hubs
Enables multi-function display docks by routing USB 3.1 Gen 1 data to integrated ports and card readers.
Stand-alone USB Hubs
Serves as the primary controller for high-throughput consumer and professional desktop hubs.
