It has been announced that the programmable EZ-PD CCG4 two-port USB-C controller with Power Delivery (PD) from Cypress Semiconductor, has been qualified by AMD for use with its 'Raven Ridge' processors for notebook and desktop PCs. The controller delivers USB and DisplayPort connectivity and fast charging to AMD’s 'Raven Ridge' reference designs, simplifying integration of plug-and-play USB-C for PC makers and accelerating time-to-market.
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.
