TUSB8043AIRGCR

Controllers Overview

The TUSB8043AIRGCR is a four-port USB 3.2 Gen 1 hub controller manufactured by Texas Instruments, designed for high-speed data expansion in compact electronic systems. It operates within a supply voltage range of 990 mV to 3.6 V and supports Super Speed (SS) data rates up to 5 Gb/s. The device utilizes an I2C interface for configuration and management, ensuring compatibility with standard host controllers. Packaged in a VQFN-64 form factor, it is optimized for surface-mount assembly. The component functions reliably across an extended industrial temperature range from -40°C to +85°C, making it suitable for demanding environments where space constraints and thermal stability are critical design factors.

Controllers Feature Summary

• Supports four downstream ports compliant with USB 3.2 Gen 1 specifications for enhanced bandwidth capabilities
• Integrates HID translation functionality to simplify host-side driver requirements for specific peripheral types
• Operates with low quiescent current consumption to optimize power efficiency in battery-powered applications

Controllers Applications

• Portable computing devices requiring multiple high-speed peripheral connections
• Industrial control systems needing robust USB expansion in harsh thermal environments
• Embedded IoT gateways utilizing I2C-controlled hub management

Controllers Procurement Notes

Verify the suffix 'RGCR' corresponds to the specific reel packaging quantity and tape width required for your automated assembly line. Confirm that the 'A' grade designation meets your operational temperature and reliability standards. Ensure your PCB layout accounts for the moisture sensitivity level indicated in the datasheet to prevent package damage during reflow soldering processes.

Controllers Selection Notes

Select this model when a four-port solution with integrated HID translation is necessary for USB 3.2 Gen 1 compliance. Compare against the TUSB8041 if HID translation is not required, as the TUSB8043AIRGCR offers additional protocol handling features. Ensure the VQFN-64 package footprint aligns with your existing board space constraints and thermal dissipation capabilities.

Controllers Part Context

This component belongs to the TUSB8043A series of USB hub controllers, representing an evolution in Texas Instruments' interface portfolio. It shares the VQFN-64 package architecture with related models like the TUSB8043RGCT but differs in commercial/industrial grading and specific feature sets such as HID translation. The part serves as a bridge between host processors and multiple USB peripherals, facilitating complex connectivity in modern embedded designs.

Controllers Replacement Considerations

The TUSB8043RGCT is a verified alternative within the same family, offering similar core functionality. Verify if the commercial temperature range of the RGCT variant suffices for your application, as the AIRGCR provides extended industrial ratings. Check for any differences in EEPROM programming tools or configuration requirements between the specific sub-models.
