TUSB3410IRHBT

Overview

The TUSB3410IRHBT is a USB-to-serial bridge controller manufactured by Texas Instruments, designed to facilitate communication between Universal Serial Bus (USB) ports and serial devices. Operating within the TUSB3410 series, this component supports USB 2.0 Full Speed data transfers at rates up to 12 Mb/s. It functions as a serial port controller housed in a VQFN-32 surface-mount package. The device operates on a 3.3 V supply voltage with a range of 3 V to 3.6 V and draws approximately 15 mA during operation. It is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Integrates RS-232 and IrDA serial interfaces for versatile connectivity
• Supports high-speed data transfers up to 921,600 bit/s for serial applications
• Enables MSP430 Flash code download directly through the USB port
• Operates at USB 2.0 Full Speed (12 Mb/s) with 3.3 V power supply

Applications

• MSP430 microcontroller USB connectivity reference designs
• Embedded systems requiring USB-to-serial bridging
• Industrial control systems needing reliable serial communication
• Consumer electronics utilizing USB debugging or programming interfaces

Procurement Notes

Verify the suffix IRHBT confirms the specific temperature grade (-40°C to +85°C), packaging type (VQFN-32), and reel quantity (250 units). Confirm RoHS compliance status via the manufacturer's datasheet before procurement. Ensure the source document explicitly lists the part number TUSB3410IRHBT to avoid confusion with other variants in the TUSB3410 family.

Selection Notes

Select the TUSB3410IRHBT when an application requires a dedicated USB-to-serial bridge for MSP430 integration or general serial emulation. The choice depends on the need for Full Speed USB performance and the specific VQFN-32 footprint constraints. Verify that the host system supports the required drivers and that the 3.3 V logic levels match the target serial interface requirements.

Part Context

This component belongs to the TUSB3410 series of USB controllers from Texas Instruments. It is specifically engineered to provide a ready-to-use solution for connecting microcontrollers, such as the MSP430, to PC hosts via USB. The IRHBT designation indicates the industrial temperature range and the specific tape-and-reel packaging format used for automated assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other USB-to-serial converters from Texas Instruments or third-party manufacturers only if they offer compatible pinouts, electrical specifications, and software driver support.
