TUSB7340RKM

Overview

The TUSB7340RKM is a SuperSpeed USB 4-port Host Controller Interface (HCI) integrated circuit manufactured by Texas Instruments. It supports the USB 3.0 standard with data rates up to 5 Gb/s. The device operates within a supply voltage range of 3 V to 3.6 V and features a low operating power current of 15 uA. It is housed in a WQFN-100 package suitable for surface mount installation. The component functions as a host/OTG controller and includes serial interface capabilities.

Feature Summary

• Provides four independent ports for SuperSpeed USB connectivity
• Integrates high-speed PHY and host controller logic
• Supports low-power standby modes for energy efficiency

Applications

• Desktop and notebook computer systems
• All-in-one printers and multifunction devices
• Industrial automation controllers

Procurement Notes

Verify the suffix 'RKM' against the official datasheet to confirm the specific tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the exact package dimensions and pinout requirements for your PCB layout. Cross-reference the manufacturer's latest documentation to validate RoHS compliance status and moisture sensitivity level before finalizing procurement.

Selection Notes

Select this component when designing systems requiring multiple high-speed USB connections from a single controller. It serves as an alternative to discrete PHY solutions, reducing board space. Consider the WQFN-100 package size during thermal management planning. Verify that the host processor supports the required serial interface protocol for communication with the controller.

Part Context

This part belongs to the TUSB7340 series of USB 3.0 host controllers. It is designed to replace legacy USB 2.0 hubs or complex multi-chip USB 3.0 designs. The series offers a consolidated solution for managing high-bandwidth peripherals in modern computing environments.

Replacement Considerations

TUSB7340RKMR is a parameter-equivalent alternative with a different reel packaging option.
