USB7006/KDX

Controllers Overview

The USB7006/KDX is a low-power, OEM-configurable USB 3.2 Gen 1 hub controller manufactured by Microchip Technology. It features six downstream ports: five standard USB 3.2 Gen 1 ports supporting SuperSpeed data rates and one standard USB 2.0 port for legacy speeds. The device integrates an internal Hub Feature Controller enabling USB-to-I2C/SPI/GPIO bridging and supports USB Link Power Management (LPM). It includes battery charging capabilities compliant with USB-IF BC1.2 standards and offers enhanced configuration options via OTP or external SPI memory. The component operates within commercial and industrial temperature ranges and is available in a 100-pin VQFN package.

Controllers Feature Summary

• Integrates an internal Hub Feature Controller to enable USB-to-I2C/SPI/I2S/GPIO bridge endpoints and direct register access.
• Supports FlexConnect functionality allowing reversible roles between upstream and downstream ports for flexible connectivity.
• Includes programmable signal integrity features such as PHYBoost for drive strength adjustment and VariSense for receive sensitivity control.
• Provides PortSplit capability to operate USB 3.2 Gen 1 and USB 2.0 portions of specific ports independently for parallel enumeration.

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.2 Gen 1 Peripherals

Controllers Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm temperature grade and packaging type. Confirm that the KDX suffix aligns with the required automotive qualification status if applicable. Ensure compatibility with the intended host system firmware requirements before procurement.

Controllers Selection Notes

Select this component when a 6-port USB 3.2 Gen 1 solution with integrated I/O bridging is required. Consider the USB7006 for designs needing FlexConnect role reversal or specific battery charging profiles. Evaluate the need for OTP versus external SPI configuration based on board space and flexibility requirements.

Controllers Part Context

The USB7006 belongs to Microchip's USB70xx family of SmartHub controllers. It shares architectural similarities with the USB7002 and USB7016 but distinguishes itself through its specific 5xUSB3/1xUSB2 port configuration and comprehensive embedded feature set for OEM customization.
