USB7002T/KDX

Controllers Overview

The USB7002T/KDX is a 4-port USB 3.2 Gen 1 SmartHub controller manufactured by Microchip Technology, housed in a 100-pin VQFN (12mm x 12mm) package with an exposed thermal pad. It supports Super-Speed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. The device features native USB Type-C support on the upstream port and two downstream ports, alongside two standard USB 2.0 downstream ports. It includes an internal Hub Feature Controller for USB-to-I2C/SPI/UART/I2S/GPIO bridging, battery charging compliance up to BC1.2, and FlexConnect role reversal capabilities.

Controllers Feature Summary

• Native USB Type-C connectivity with integrated CC pin logic and multiplexer for orientation detection
• Internal Hub Feature Controller enabling USB-to-peripheral interface bridging via I2C, SPI, UART, I2S, or GPIO
• FlexConnect technology allowing any downstream port to be reconfigured as the upstream host port
• Support for USB-IF Battery Charging Revision 1.2 profiles including DCP, CDP, and SDP

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Automotive integrated head units and breakout boxes

Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tray packaging when sourcing components. Confirm that the KDX designation aligns with the required automotive AEC-Q100 qualification grade. Ensure the order quantity matches the manufacturer's standard reel size of 2,500 units to avoid potential repackaging fees or minimum order discrepancies from distributors.

Controllers Selection Notes

Select this component for designs requiring native USB Type-C integration on multiple ports without external protocol controllers. The internal Hub Feature Controller reduces system complexity by providing direct access to hub registers and peripheral interfaces. Consider the 100-VQFN package constraints for thermal management and PCB layout, particularly regarding the exposed pad connection to ground for optimal heat dissipation during high-speed data transfers.

Controllers Part Context

The USB7002 series represents Microchip's fourth-generation USB hub feature controller architecture. This model specifically targets OEM applications needing flexible configuration through OTP or SPI ROM. It decouples SuperSpeed traffic from USB 2.0 bottlenecks using parallel controllers. The T suffix variant denotes the roll-packaged version of the automotive-grade silicon, distinct from the tray-packed commercial or industrial equivalents.
