USB7252CT/KDX

Controllers Overview

The USB7252CT/KDX is a 4-port USB 3.2 Gen 2 hub controller by Microchip Technology, housed in a 100-pin VQFN (12mm x 12mm) package. It features one upstream Type-B port and four downstream ports: two native USB 3.2 Gen 2 Type-C ports with Power Delivery support, one standard USB 3.2 Gen 2 port, and one standard USB 2.0 port. The device supports data rates of 10 Gbps, 5 Gbps, 480 Mbps, 12 Mbps, and 1.5 Mbps. Operating voltage ranges from 1.09V to 1.21V for core logic and 3V to 3.6V for I/O. It includes an internal Hub Feature Controller, 96kB RAM, 256kB ROM, and 8kB OTP memory.

Controllers Feature Summary

• Native USB Type-C support on downstream ports with integrated CC logic and multiplexers
• Internal Hub Feature Controller enabling USB-to-I2C/SPI/UART/I2S/GPIO bridging
• Support for USB-IF Battery Charging revision 1.2 profiles including DCP, CDP, and SDP
• OEM configuration options via Configuration Straps, external SPI memory, or OTP ROM

Controllers Applications

• Standalone USB Hubs
• Laptop Docks
• PC Motherboards
• Multi-function USB 3.2 Gen 2 Peripherals

Controllers Procurement Notes

Verify the specific suffix 'CT' indicates Cut Tape packaging when sourcing components. Confirm that the device status aligns with current availability as distribution channels may vary. Ensure compatibility with required operating temperature ranges, specifically commercial (0°C to +70°C) or industrial (-40°C to +85°C) grades, before finalizing procurement plans.

Controllers Selection Notes

Select this component for designs requiring native Type-C connectivity with Power Delivery capabilities on multiple downstream ports. The integrated Hub Feature Controller is suitable for applications needing embedded USB-to-peripheral bridging without additional controllers. Consider the 100-pin VQFN package constraints and thermal requirements for high-speed signal integrity in dense PCB layouts.

Controllers Part Context

This part belongs to the USB7252C series of USB 3.2 Gen 2 hub controllers. It is designed for OEM customization through flexible configuration methods. The device decouples SuperSpeed data transfers from slower USB 2.0 traffic using parallel controllers, enhancing performance in complex peripheral systems.
