TUSB321AIRWBR

Specialized Overview

The TUSB321AIRWBR is a USB Type-C Configuration Channel (CC) Logic and Port Control integrated circuit manufactured by Texas Instruments. It supports the USB Type-C Specification Revision 1.1 and operates at Super Speed data rates up to 5 Gb/s. The device functions as a Dual-Role Port (DRP) controller with a supply voltage range of 4.5 V to 5.5 V and a typical operating current of 70 uA. It is housed in a 12-pin X2QFN package and is rated for an operating temperature range from -40°C to +85°C.

Specialized Feature Summary

• Integrates CC logic and port control for USB Type-C compliance
• Supports Super Speed data transmission up to 5 Gb/s
• Operates as a Dual-Role Port (DRP) controller

Specialized Applications

• USB Type-C host or device port controllers
• Super Speed USB 3.1 interface implementations
• Dual-role power and data connection management

Specialized Procurement Notes

Verify the specific suffix 'AIRWBR' against the manufacturer's official datasheet to confirm the exact temperature grade, packaging format, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the X2QFN-12 package and validate that the 4.5V to 5.5V supply range aligns with the system design requirements.

Specialized Selection Notes

Select this component when a dedicated USB Type-C CC logic controller is required for Super Speed applications. It is suitable for designs needing DRP functionality without an external MCU for basic port negotiation. Compare against the standard TUSB321RWBR if industrial temperature ratings (-40°C to +85°C) are necessary instead of commercial ranges.

Specialized Part Context

This part belongs to the TUSB321AI series of USB Type-C controllers. It is distinct from signal redrivers like the TUSB211 or multiplexers like the HD3SS3220, focusing specifically on configuration channel logic and port state management rather than signal integrity enhancement or analog switching.

Specialized Replacement Considerations

The TUSB321RWBR is a related variant within the same family, typically differing in operating temperature range. Verify pinout and electrical characteristics before substitution.
