TUSB3410IRHBR

Overview

The TUSB3410IRHBR is a USB to serial port controller manufactured by Texas Instruments, designed to convert Universal Serial Bus (USB) signals into RS-232 or IrDA serial communication protocols. It operates as a Full Speed (FS) device compliant with the USB 2.0 standard, supporting data rates up to 12 Mb/s. The component functions on a single 3.3 V power supply and is housed in a VQFN-32 surface-mount package. It supports both host and peripheral modes, enabling flexible integration into systems requiring legacy serial connectivity via modern USB interfaces.

Feature Summary

• Integrated USB 2.0 Full Speed controller with 12 Mb/s data rate
• Supports RS-232 and IrDA serial protocol conversion
• Operates at 3.3 V with -40°C to +85°C industrial temperature range
• Available in compact VQFN-32 SMD/SMT package

Applications

• Converting legacy RS-232 devices to USB hosts
• Integrating IrDA modules with USB-enabled systems
• Industrial equipment interfacing requiring serial-to-USB bridges

Procurement Notes

Verify the suffix IRHBR confirms the specific reel packaging and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification.

Selection Notes

Select this component when a dedicated USB-to-serial bridge is required for RS-232 or IrDA applications without external transceivers. The fixed 3.3 V operating voltage limits suitability for 5 V logic systems unless level shifting is provided externally. The VQFN-32 package requires appropriate PCB thermal relief design for soldering.

Part Context

This part belongs to the TUSB3410 series of USB controllers from Texas Instruments. It serves as a specialized interface solution for bridging high-speed USB buses with lower-speed asynchronous serial standards. The IRHBR variant specifically denotes the industrial temperature range and tape-and-reel packaging format.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate other members of the TUSB3410 family, such as TUSB3410RHBG4, for pin-compatible alternatives if different packaging or voltage tolerances are required.
