Next-Gen PCs Seriously Need This Tiny USB C Hub Solution With PD


Cypress claims the industry’s first USB Type-C hub controller with USB Power Delivery which greatly reduces system design complexity for a new generation of notebook docking stations, monitors and accessories. HX3C can help customers save 30% on PCB size and 10% on BOM cost compared to discrete solutions.

New EZ-USB HX3C controller integrates four chips (USB Hub, USB Billboard and two USB PD controllers) into one, reducing BOM cost and solution footprint. It is packed into a space-saving, 10 mm by 10 mm BGA package, making it ideal for USB Type-C dongles, docks and monitors.

“The HX3C  is the most compelling USB hub solution for any applications requiring multiple USB Type-C ports supporting Power Delivery and battery charging standards”, says the company.

Technical Details

The HX3C supports one downstream Type-C port and one upstream Type-C port. It integrates USB 3.0 hub, integrating a USB Billboard controller, an ARM Cortex-M0 CPU, 64KB flash, two Type-C transceivers, Type-C termination resistors, an ADC for overvoltage and overcurrent detection, Battery Charging Spec v1.2, Apple charging detection and ±15-kV ESD protection.

The two ARM Cortex-M0 CPUs of the HX3C are optimized for low-power operation with extensive clock gating. It uses 16-bit instructions and executes a subset of the Thumb-2 instruction set. This enables fully compatible binary upward migration of the code to higher performance processors.

The CPU also has a nested vectored interrupt controller (NVIC) block with 32 interrupt inputs and a Wakeup Interrupt Controller (WIC). The WIC can wake up the CPU from the Deep Sleep mode, allowing power to be switched off to the main processor when HX3C is in Deep Sleep.

New Programmable SoC for Slimmer, Next-Generation USB Type-C Designs

Type-C USB standard

“USB Type-C’s slim mechanical design, reversible plug orientation, scalable Power Delivery and Alternate Modes provide end-users with an easy-to-use, single-cable solution for data, video and power,” said Jeff Ravencraft, USB-IF President and COO. “We welcome Cypress’s continued expansion of its USB Type-C and Power Delivery portfolio, which adds to the rapid growth of the USB ecosystem.”

According to IHS and Cypress estimates, USB Type-C device shipments are expected to grow from 50 million units in 2015 to over more than 2 billion in 2019. This is by virtue of the advantages offered by the USB Type-C standard — enabling the transfer of data, power and video to PCs, tablets and smartphones and replacing multiple connectors with a single connector, smaller 2.4-mm-height USB Type-C plug than 4.5-mm USB Type-A plug, and allowing for transport of USB signals and DisplayPort, MHL, or Thunderbolt signals via the Alternate Mode capability on the same connector.


The HX3C controller is currently sampling and is expected to be in production in the third quarter of 2016. It is available in a 121-ball  (10mm X10 mm) BGA package specified to operate in the commercial and industrial temperature range.
