USB7050T-I/KDX

Controllers Overview

The USB7050T-I/KDX is a USB interface integrated circuit manufactured by Microchip Technology, functioning as a SmartHub controller compliant with USB 3.1 Gen 1 standards. It features a four-port architecture comprising two downstream Type-C ports with CC pin support and two downstream Type-A ports. The device integrates native Type-C upstream connectivity with Charge Controller (CC) pin support for power management negotiation. It operates within an industrial temperature range and utilizes a 100-VQFN package measuring 12x12 mm. The component supports Super Speed data rates up to 5 Gb/s and Hi-Speed rates up to 480 Mbps, providing a unified solution for multi-port USB expansion in automotive and industrial applications requiring robust connectivity.

Controllers Feature Summary

• Integrates dual downstream Type-C ports with dedicated CC pin support alongside dual downstream Type-A ports for versatile peripheral connectivity.
• Features native Type-C upstream interface capability allowing direct connection to host systems without external protocol converters.
• Supports intelligent port control and power distribution management through the SmartHub architecture for optimized energy efficiency.
• Complies with AEC-Q100 automotive qualification standards ensuring reliability under demanding environmental conditions.

Controllers Applications

• Automotive infotainment systems requiring multiple high-speed peripheral connections
• Industrial control panels needing robust USB expansion with Type-C compatibility
• Medical equipment interfaces requiring certified automotive-grade connectivity components

Controllers Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct package type and temperature grade alignment. Confirm RoHS compliance status and REACH registration details prior to integration. Check for any recent Product Change Notifications regarding assembly sites or material updates. Ensure ESD handling procedures are followed during storage and installation due to the sensitivity of the VQFN package contacts.

Controllers Selection Notes

Select this component when a design requires a single-chip solution for expanding USB 3.1 Gen 1 connectivity with mixed Type-C and Type-A downstream ports. It is suitable for applications necessitating native Type-C upstream attachment and automotive-grade reliability. Compare against the USB7002 series if lower port counts or consumer-grade specifications suffice. Verify that the 100-VQFN footprint matches the target PCB layout constraints.

Controllers Part Context

This part belongs to the Microchip USB70xx family of SmartHub controllers designed for complex USB topology management. It complements other variants like the USB7051 and USB7052 which offer different port configurations or temperature ranges. The T suffix typically indicates tape and reel packaging for automated assembly, distinguishing it from tray-packaged equivalents. This series addresses the growing demand for Type-C integration in legacy USB infrastructure.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the USB7052N-I/KDX for similar port configurations but verify package and temperature differences. Cross-reference with the USB7002 series for basic hub functionality if Type-C upstream features are not required. Consult Microchip technical support for qualified alternates matching specific automotive qualification requirements.
