USB7216/KDX

Controllers Overview

The USB7216/KDX is a 6-port USB 3.2 Gen 2 Smart Hub controller manufactured by Microchip Technology, housed in a 100-pin VQFN package measuring 12mm x 12mm. It supports data rates of 10 Gbps (SS+), 5 Gbps (SS), 480 Mbps (HS), 12 Mbps (FS), and 1.5 Mbps (LS). The device features native USB Type-C support on downstream port 1 with integrated CC logic, three standard USB 3.2 Gen 2 ports, and two standard USB 2.0 ports. Operating voltage ranges from 1.09V to 1.21V for core logic and 3V to 3.6V for I/O. It operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and package variant. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compatibility with required host drivers such as Windows 10, 8, 7, XP, Apple OS X, and Linux before procurement.

Controllers Selection Notes

Select this component for designs requiring a high-speed hub with native Type-C capability on at least one downstream port. Consider the internal Hub Feature Controller if system management via USB-to-peripheral bridging is needed. Verify that the 100-pin VQFN footprint fits the PCB layout constraints and that the operating temperature range matches the environmental requirements.

Controllers Part Context

The USB7216 belongs to Microchip's USB72xx series of USB 3.2 Gen 2 hub controllers. It is designed for OEM customization through configuration straps, external SPI memory, or OTP programming. The device decouples SuperSpeed transfers from USB 2.0 traffic bottlenecks using parallel controllers.

Controllers FAQ

Does the USB7216 require an external multiplexer for Type-C support?

No, the USB7216 includes an internal USB 3.2 Gen 2 multiplexer on the Type-C enabled downstream port 1, eliminating the need for an external multiplexer.

What battery charging standards are supported?

The device supports USB-IF Battery Charging revision 1.2, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Standard Downstream Port (SDP) profiles.

How is the device configured for OEM use?

Configuration can be performed using hardware configuration straps, programming firmware images to external SPI memory devices, or utilizing the internal 8kB One-Time-Programmable (OTP) ROM.
