TUSB8044RGCR

Controllers Overview

The TUSB8044RGCR is a four-port USB 3.1 hub controller manufactured by Texas Instruments, designed for SuperSpeed data transfer at rates up to 5 Gb/s. It operates within a supply voltage range of 990 mV to 3.6 V and draws a typical operating current of 30 mA. The device supports an industrial temperature range from 0°C to +70°C and utilizes an I2C interface for configuration. Packaged in a 64-pin VQFN format, this component serves as a high-performance hub solution for expanding USB connectivity in embedded systems.

Controllers Feature Summary

• Supports four downstream ports with SuperSpeed (SS) capabilities compliant with the USB 3.1 standard.
• Utilizes an I2C interface for host-side control and configuration management.
• Operates on dual power rails, accommodating 1.1 V and 3.3 V supply voltages.

Controllers Applications

• Expanding USB connectivity in desktop computers and all-in-one PCs
• Integrating multiple peripherals into industrial automation controllers
• Adding USB expansion capabilities to medical imaging equipment

Controllers Procurement Notes

Verify the specific revision level and manufacturing date code upon receipt, as the TUSB8044RGCR is designated as Not Recommended for New Designs (NRND). Confirm that the VQFN-64 package matches the footprint requirements of the target PCB layout. Ensure compliance with RoHS directives if required by the end-product specifications before finalizing procurement orders.

Controllers Selection Notes

Select the TUSB8044ARGCR or TUSB8044AIRGCR variants if extended temperature ranges or updated lifecycle status are required, as the RGCR variant is obsolete. Consider the TUSB8042 series for applications requiring identical pinouts but potentially different thermal or electrical characteristics. Verify that the system design accommodates the 64-VQFN package dimensions and thermal dissipation needs.

Controllers Part Context

This component belongs to the TUSB8044 family of USB hub controllers from Texas Instruments. It shares architectural similarities with the TUSB8042 and TUSB8044A series, offering comparable functionality for multi-port USB expansion. The RGCR suffix indicates a specific reel packaging configuration used for surface-mount assembly processes.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers include TUSB8044ARGCR and TUSB8044AIRGCR. These variants offer similar functional interfaces but may differ in lifecycle status and temperature ratings. Evaluate pin compatibility and firmware requirements when transitioning from the NRND TUSB8044RGCR to these alternatives.
