USB7002T-I/KDX

Controllers Overview

The USB7002T-I/KDX is a 4-port USB 3.2 Gen 1 SmartHub IC manufactured by Microchip Technology, housed in a 100-pin VQFN (12mm x 12mm) package. It features native USB Type-C support on the upstream port and two downstream ports, alongside two standard USB 2.0 downstream ports. The device supports SuperSpeed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operations. It includes an internal Hub Feature Controller for USB-to-I2C/SPI/UART/I2S/GPIO bridging, 64kB RAM, 256kB ROM, and 8kB OTP. The component is AEC-Q100 qualified for automotive applications and operates within commercial and industrial temperature ranges.

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 I2C, SPI, UART, I2S, and GPIO bridge endpoints
• Supports FlexConnect role reversal allowing any downstream port to function as the upstream host port
• Integrated battery charging detection supporting USB-IF BC1.2 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 ordering suffix 'T' indicates tape-and-reel packaging when sourcing from distributors. Confirm the '-I' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the 'KDX' suffix matches the required 100-VQFN package variant. Cross-reference the manufacturer part number with official Microchip documentation to confirm current production status and revision level before finalizing procurement.

Controllers Selection Notes

Select this component for designs requiring a compact, OEM-configurable hub with native Type-C capabilities. It is suitable for applications needing simultaneous SuperSpeed and legacy USB 2.0 connectivity. Consider the internal Hub Feature Controller if system monitoring via I2C or GPIO is required. Verify that the 100-pin VQFN package fits the PCB layout constraints and thermal requirements of the target enclosure.

Controllers Part Context

The USB7002T-I/KDX belongs to the USB7002 family of USB 3.2 Gen 1 SmartHub controllers. It shares core functionality with variants like the USB7002-KDX but differs in packaging and configuration options. The 'T' suffix typically denotes reel packaging, while 'I' specifies the industrial temperature grade. This series is designed for high-performance embedded USB applications requiring advanced power management and flexible port configurations.

Controllers Replacement Considerations

Direct substitutes include other USB7002 variants such as USB7002-KDX for tray packaging or USB7002T/KDX for different temperature grades. Ensure compatibility with existing firmware and hardware design when switching between package types or temperature ratings.
