Integrated solution for desktops with two USB-C ports

The EZ-PD CCG4 controller offers a reliable and integrated solution for desktops, notebooks and other systems with two USB-C ports. The controller includes 128KB flash memory that can store dual-firmware images for a fail-safe boot, increasing the reliability of the system, and it enables firmware updates in the field. It offers programmability to keep up with evolving industry standards.

“Qualification of our EZ-PD controllers by AMD has put Cypress in a prime position to drive the ramp of USB-C connectivity in the PC market,” said Ajay Srikrishna, Vice President of Cypress’ Wired Connectivity Business Unit. “Our leading USB-C solutions such as EZ-PD CCG4, the industry’s first two-port USB-C controller, make it easy for our customers to bring the benefits of reliable, USB-IF-certified USB-C connectivity and fast charging to the market.”

Stephanie Smith, Director, Client Program Management and Technology Enablement, AMD, said: “Enabling a plug-and-play user experience is critical in the PC market, so we put a premium on selecting a market-proven, USB-IF-certified USB-C controller to pair with our ‘Raven Ridge’ processors. Cypress’ EZ-PD CCG4 controller brings programmability, interoperability and USB-IF certification to our platform and reference design.”

In the 'Raven Ridge' reference design, the EZ-PD CCG4 controller interfaces with the embedded controller to enable the use of USB Type-C Connector System Software Interface (UCSI), which is a standardised mechanism for operating systems to monitor and control power delivery and the multiple protocols on a USB-C port in a PC. The programmable CCG4 solution enables UCSI and custom firmware development using the EZ-PD software development kit (SDK) and the Cypress Host Processor Interface (HPI). The CCG4 controller also controls the 'Raven Ridge' processor’s built-in USB-DisplayPort mux over I2C, controlling the switching of the USB 3.1 Generation 2 signals and DisplayPort signals on the USB-C port.
