USB7050PT/KDX

Controllers Overview

The USB7050PT/KDX is a 4-port USB 3.2 Gen 1 SmartHub IC manufactured by Microchip Technology in a 100-pin VQFN package. It supports SuperSpeed (SS) at 5 Gbps, Hi-Speed (HS) at 480 Mbps, Full-Speed (FS) at 12 Mbps, and Low-Speed (LS) at 1.5 Mbps. The device features native USB Type-C support with Power Delivery on the upstream port and downstream ports 1 and 2. It includes an internal Hub Feature Controller for USB-to-I2C/SPI/UART/GPIO bridging, 64kB RAM, 256kB ROM, and 8kB OTP. Operating voltage ranges from 1.2V to 3.6V, with commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature grades.

Controllers Feature Summary

• Native USB Type-C support with integrated multiplexers and Power Delivery management for up to three ports.
• Internal Hub Feature Controller enabling USB-to-I2C, SPI, UART, I2S, and GPIO bridging capabilities.
• Multi-Host Endpoint Reflector allowing USB data mirroring between two hosts via CDC/NCM device class.
• Configurable FlexConnect allowing any downstream port to be reconfigured as the upstream port.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific suffix 'PT' against official documentation to confirm package type and temperature grade. Confirm current availability status as distribution channels may vary. Ensure compatibility with required external PD transceivers such as UPD350 or UPD360 for full Power Delivery functionality.

Controllers Selection Notes

Select this component for designs requiring native Type-C connectivity with Power Delivery on multiple ports. Consider the internal Hub Feature Controller if system monitoring via I2C or SPI is needed. Verify that the 100-pin VQFN package fits the PCB layout constraints and thermal requirements of the target application.
