USB5734T/MRD01

Controllers Overview

The USB5734T/MRD01 is a high-speed USB controller hub integrated circuit manufactured by Microchip Technology. It functions as a smart hub supporting four downstream ports with USB 3.1 Gen 1 capabilities. The device incorporates an embedded microcontroller unit (MCU) to manage port operations and power distribution. It provides bridging interfaces for industry-standard I2C, SPI, and UART peripherals, expanding host connectivity beyond standard USB protocols. The component supports advanced features such as host and device port swapping and includes port power controllers capable of managing up to 45W DC power per port.

Controllers Feature Summary

• Integrated MCU for simplified software complexity and reduced bill of materials
• Non-USB bridging ports for I2C, SPI, and UART peripheral connectivity
• Support for USB Type-C connectors with downstream cable orientation indication
• Host and device port swapping functionality

Controllers Applications

• Smart hub designs utilizing USB Type-C interfaces
• Embedded systems requiring expansion to non-USB serial peripherals
• Development boards featuring battery charging and serial communication
• Applications requiring high-power downstream port management

Controllers Procurement Notes

Verify the specific suffix RD01 against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating voltage levels and interface standards before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and manufacturing status.

Controllers Selection Notes

Select this component when a USB 3.1 Gen 1 hub with integrated control logic is required. It is suitable for designs needing direct support for I2C, SPI, or UART bridges without additional external controllers. Consider its power handling capabilities if downstream ports require significant DC power delivery. Evaluate the embedded MCU features to determine if they meet the specific firmware requirements for port management.

Controllers Part Context

The USB5734 series represents Microchip's approach to intelligent USB hubs by integrating processing capabilities directly into the hub controller. This design reduces the need for separate host processors to manage hub states. The USB5734T variant specifically denotes the temperature range and packaging configuration within the broader USB5734 product family, which also includes models like the USB5744.

Controllers Replacement Considerations

Direct substitutes may include other Microchip USB 3.1 smart hubs such as the USB5744, depending on specific pinout and feature requirements. Verify electrical characteristics and interface compatibility before replacing. Generic USB hubs lacking integrated MCUs or bridging capabilities are not functionally equivalent.
