USB7206/KDX

Controllers Overview

The Microchip USB7206/KDX is a low-power, OEM-configurable USB 3.2 Gen 2 hub controller featuring six downstream ports and advanced embedded features. It supports data rates of 10 Gbps (SS+), 5 Gbps (SS), 480 Mbps (HS), 12 Mbps (FS), and 1.5 Mbps (LS). The device includes five standard USB 3.2 Gen 2 downstream ports and one standard USB 2.0 downstream port. It operates within a voltage range of 1.09 V to 3.6 V and functions in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges. The component is housed in a 100-pin VQFN package.
