Cypress Semiconductor has announced that its USB-C technology is enabling people to use their smartphones as a desktop computer with the Samsung DeX Station. The Samsung DeX allows users to dock their Galaxy S8 and S8+ smartphones via a USB-C port and use apps, review documents, and set or check notifications in a desktop environment, as well as send and receive text messages and make phone calls.

Cypress’ four-chip USB-C dock solution charges phones quickly through the USB-C port and provides plug-and-play connectivity to a monitor, keyboard, mouse and a variety of USB peripherals.

“The innovative Samsung DeX is a critical piece in making the smartphone-as-a-pocket-PC usage model a reality, and we’re proud that Cypress USB-C is supporting this new class of enterprise application,” said Ajay Srikrishna, Vice President of the Wired Connectivity Business Unit at Cypress. “We optimised our USB-C dock solution to charge smartphones while providing the simple, one-cable connection from the smartphone to the peripherals needed to create a desktop experience.”

Cypress’ robust USB-C dock solution enables multiple functions on the DeX Station. Two EZ-PD CCG2 CYPD2122 controllers enable power delivery and smart device charging, with one controlling power upstream to the smartphone and the other controlling power downstream to peripherals. The CYP65632 USB 2.0 hub controller allows two USB devices and an Ethernet port to connect to the host smartphone. The CY7C65210 billboard controller enables an improved user experience by preventing connection failures due to mismatched capabilities between peripherals and the smartphone, while enabling firmware upgrades to both USB-C controllers.
