TUSB3410RHBR

Overview

The TUSB3410RHBR is a USB to Serial Port Controller manufactured by Texas Instruments, designed to convert Universal Serial Bus (USB) signals into serial communication protocols. It supports RS-232 and IrDA interfaces, enabling connectivity between USB hosts and legacy serial devices. The device operates at Full Speed (FS) with a data rate of 12 Mb/s, compliant with the USB 2.0 standard. It functions on a single 3.3 V power supply, drawing approximately 15 mA during operation. The component is housed in a VQFN-32 surface-mount package and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates USB 2.0 Full Speed controller with RS-232 and IrDA serial interface capabilities
• Operates on a single 3.3 V power supply with low current consumption of 15 mA
• Available in compact VQFN-32 surface-mount packaging for space-constrained designs
• Supports industrial operating temperatures ranging from -40°C to +85°C

Applications

• Converting USB host connections to RS-232 serial ports for legacy equipment
• Enabling IrDA wireless serial communication via USB interfaces
• Industrial control systems requiring robust serial-to-USB conversion
• Embedded systems integrating USB connectivity with UART-based peripherals

Procurement Notes

Verify the suffix 'RHB' corresponds to the specific reel packaging configuration required for automated assembly processes. Confirm that the voltage specifications align with the target system's 3.3 V rail, as the device is optimized for this supply level. Ensure compliance with humidity sensitivity handling procedures due to the moisture-sensitive nature of the VQFN package. Cross-reference the revision level against the latest datasheet to confirm pinout and electrical parameter consistency.

Selection Notes

Select the TUSB3410RHBR when a Full Speed USB interface is sufficient for serial data transmission rates up to 12 Mb/s. This part is appropriate for applications requiring both RS-232 and IrDA support within a single integrated circuit. Consider the VQFN-32 package dimensions for PCB layout constraints. If High Speed (480 Mb/s) performance is required, a different controller class must be selected. Verify that the host system provides adequate 3.3 V power delivery within the specified current limits.

Part Context

The TUSB3410RHBR belongs to the TUSB3410 family of USB to Serial controllers from Texas Instruments. This series is engineered to bridge modern USB hosts with traditional serial devices. The RHBR suffix indicates the tape-and-reel packaging variant, distinct from tube-packaged versions like the TUSB3410RHB. The family shares core functional blocks, including the USB PHY and serial engine, while differing primarily in packaging and manufacturing lot configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering changes or obsolescence may require evaluation of alternative USB-to-Serial controllers from Texas Instruments or other manufacturers, ensuring compatibility with USB 2.0 Full Speed standards and VQFN-32 footprints.
