TUSB3410RHBG4

Overview

The TUSB3410RHBG4 is a USB-to-serial bridge controller manufactured by Texas Instruments, designed to convert RS232 or IrDA serial interfaces to USB. It operates within a voltage range of 3 V to 3.6 V, with a typical operating supply current of 15 mA. The device supports USB 2.0 Full Speed (FS) data transfers at a maximum rate of 12 Mb/s. It is housed in a VQFN-32 surface-mount package and functions as a serial port controller compatible with standard USB protocols.

Feature Summary

• Integrates USB 2.0 Full Speed interface with serial port controller functionality
• Supports high-speed data transfers up to 921,600 bit/s for connected peripherals
• Enables MSP430 Flash code download directly through the USB port
• Operates on a single 3.3 V power supply with low current consumption

Applications

• MSP430 microcontroller USB connectivity reference designs
• RS232/IrDA to USB conversion for legacy serial devices
• Embedded systems requiring USB-based firmware programming
• Industrial control interfaces utilizing serial communication protocols

Procurement Notes

Verify component authenticity against Texas Instruments specifications before integration. Confirm that the VQFN-32 package dimensions match the target PCB footprint. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Validate driver compatibility with the host operating system for reliable serial emulation.

Selection Notes

Select this component when a dedicated USB-to-serial bridge is required for embedded applications. It is suitable for designs involving MSP430 microcontrollers needing USB programming capabilities. Consider the 12 Mb/s USB speed limit if higher bandwidth is necessary. Verify that the 3.3 V supply rail aligns with the system's power architecture.

Part Context

This part belongs to the TUSB3410 series of USB controllers. It is often used in conjunction with the TUSB3410UARTPDK development kit for rapid prototyping. The device serves as an interface between host computers and serial-enabled slave devices, simplifying USB implementation in microcontroller-based systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative USB-to-serial controllers from Texas Instruments or other manufacturers based on pin compatibility and functional requirements.
