USB7052-I/KDX

Overview

The USB7052-I/KDX is a 4-port USB 3.2 Gen 1 SmartHub IC manufactured by Microchip Technology, designed for embedded applications with native Type-C support and Power Delivery capabilities on the upstream port. It features two downstream ports with native Type-C connectivity and integrated multiplexers, one standard USB 3.2 Gen 1 downstream port, and one standard USB 2.0 downstream port. The device supports SuperSpeed (5 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data rates. It includes an internal Hub Feature Controller enabling USB-to-I2C/SPI/UART/GPIO bridging, battery charging detection compliant with BC1.2, and OEM configuration via OTP or SPI ROM. Operating within an industrial temperature range of -40°C to +85°C, it utilizes a 100-pin VQFN package.

Feature Summary

• Native USB Type-C support on downstream ports with integrated CC logic and multiplexers
• Integrated USB Power Delivery controller for managing up to three Type-C ports
• USB Bridging capability allowing connection to I2C, SPI, UART, I2S, and GPIO interfaces
• Supports USB-IF Battery Charging revision 1.2 profiles including DCP, CDP, and SDP

Applications

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

Procurement Notes

Verify the specific suffix '-I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'KDX' suffix matches the required 100-VQFN package variant. Ensure compatibility with external PD transceivers like the UPD350 or UPD360 if Power Delivery functionality is required. Check for any silicon errata sheets relevant to the specific manufacturing revision before finalizing design integration.

Selection Notes

Select this component when a compact 4-port hub solution with native Type-C and Power Delivery is needed. It is suitable for designs requiring flexible port roles via FlexConnect or specialized bridging functions. Consider the -I variant for environments exceeding commercial temperature limits. Verify that the host system can support the required 25 MHz clock source for the crystal oscillator interface.

Part Context

The USB7052 belongs to Microchip's USB70xx series of USB 3.2 Gen 1 hub controllers. This family focuses on providing advanced OEM configurability and low-power operation for modern computing platforms. The USB7052 specifically targets applications needing a mix of legacy USB 2.0 and high-speed USB 3.2 connectivity alongside Type-C standards.
