Texas Instruments TUSB321
The TUSB321 device enables USB Type-C ports with the configuration channel (CC) logic needed for TypeC ecosystems. The TUSB321 device uses the CC pins to determine port attach and detach, cable orientation, role detection, and port control for Type-C current mode. The TUSB321 device can be configured as a downstream facing port (DFP), upstream facing port (UFP) or a dual role port (DRP) making it ideal for any application.| Part No. | TUSB321 |

DESCRIPTION
The TUSB321 device when configured as a DRP alternates configuration as a DFP or UFP according to the Type-C Specifications. The CC logic block monitors the CC1 and CC2 pins for pullup or pulldown resistances to determine when a USB port has been attached, the orientation of the cable, and the role detected.
