Integrated USB Type-C Hub Controller with USB Power Delivery

May 31, 2016 // By Graham Prophet
Cypress has introduced the EZ-USB HX3C controller that integrates functions previously requiring up to four chips; it provides a low-component-count, spcae-efficient, USB 3.1 Gen 1, USB Type-C and Power Delivery Hub

The USB Type-C and Power Delivery specifications from the USB Implementers Forum (USB-IF) are gaining support with top-tier PC makers by enabling slim industrial designs, easy-to-use connectors and cables, the ability to transmit multiple protocols, and delivery of up to 100W of power – a significant improvement over the previous 7.5W standard.


Cypress’s HX3C solution integrates a USB 3.1 Gen 1 hub controller, a USB Billboard controller and two USB Type-C port controllers into a 10 by 10 mm BGA package. The hub controller presents itself to connected devices as a compound hub, providing three exposed downstream ports and one non-removable port. The two USB Type-C port controllers are associated with the upstream port and one downstream port of the hub, supporting Dual Role Port (DRP) on the upstream port and Down Facing Port (DFP) on the downstream port. The non-removable port is permanently attached to the embedded USB Billboard controller, which can be enabled or disabled via configuration settings. In addition to USB Power Delivery, HX3C supports USB Battery Charging v1.2 (BC 1.2) and Apple charging standards on all of its downstream ports, providing a complete USB charger solution for portable electronics.

“Applications requiring multiple USB Type-C ports supporting Power Delivery and battery charging standards can save [up to] 30% on PCB size and 10% on BOM cost compared to discrete solutions,” said Mark Fu, Sr. Marketing Director of Cypress’s USB Business Unit. “HX3C reduces system design complexity of USB Type-C docking stations, monitors and accessories.”
