TUSB321RWBR

Specialized Overview

The TUSB321RWBR is a USB Type-C Configuration Channel Logic and Port Control integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports SuperSpeed data rates compliant with USB 1.1 standards. The device is designed for single-port applications, specifically functioning as a Downstream Facing Port (DFP). It features an extended commercial operating temperature range from 0°C to +70°C. The component is housed in a compact 12-pin X2QFN package, suitable for surface mount technology (SMD/SMT) assembly.

Specialized Feature Summary

• Integrates CC logic and port control functions for USB Type-C configurations
• Supports SuperSpeed data transmission capabilities
• Includes VCONN management functionality

Specialized Applications

• USB Type-C port controller implementations
• SuperSpeed USB interface designs
• VCONN power management circuits

Specialized Procurement Notes

Verify the specific suffix RWBR against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component matches the commercial temperature grade requirements for the intended application environment before finalizing procurement orders.

Specialized Selection Notes

Select this component when a dedicated USB Type-C configuration channel controller with SuperSpeed support is required. Verify that the 0°C to +70°C operating temperature range aligns with the system's thermal constraints. Confirm compatibility with the 4.5 V to 5.5 V power supply rails available in the design.

Specialized Part Context

This part belongs to the TUSB321 series of USB interface controllers. It serves as a specialized solution for managing USB Type-C connections, distinct from general-purpose USB hubs or transceivers. The series focuses on providing essential logic for port configuration and control without integrating full high-speed PHY layers.

Specialized Replacement Considerations

Consult official substitution guides for variants such as TUSB321AIRWBR, which offers an extended industrial temperature range. Verify pinout and functional compatibility before replacing the standard commercial grade part with industrial grade alternatives.
