SAN FRANCISCO, CA --- Cypress Semiconductor’s USB-C controller portfolio now supports the latest USB Power Delivery (PD) 3.0 specification enabling more robust end-to-end power delivery and charging solutions for laptop and mobile devices. USB PD 3.0 provides a number of key enhancements over the current version of the spec, USB PD 2.0, to enhance robustness in power sources, sinks and cables. Cypress's EZ-PD™ CCG3 and CCG4 USB-C port controllers are the industry's first solutions to support the USB PD 3.0 specification from the USB Implementers Forum (USB-IF). More information on Cypress's USB PD 3.0 solutions is available at www.cypress.com/USBPD3.0.
USB PD 3.0 provides the ability for an accessory to change modes from sourcing to sinking power quickly, preventing data corruption during a sudden disconnect of its power source. This feature, called fast role swap, enables charge-through dongles and docks. USB PD 3.0 also introduces an extended messaging capability that enables faster USB PD performance for firmware updates and offers a more-efficient mechanism to exchange security certificates. The extended messages can carry data payloads of up to 260 bytes, more than nine times the 28 bytes allowed in USB PD 2.0. USB PD 3.0 is fully backward-compatible with USB PD 2.0.
Cypress's portfolio of programmable USB-C controllers with PD 3.0 support includes EZ-PD CCG3, the most-integrated USB-C solution with authentication, and CCG4, the world's first two-port USB-C solution. The EZ-USB HX3C, the world's first USB-C PD hub controller, and EZ-PD CCG2, the smallest programmable USB-C solution, will add PD 3.0 support via a firmware upgrade later this year. Cypress is demonstrating its complete portfolio of USB-C and PD solutions at the Intel Developer Forum from August 16-18 in booth number 164 at the Moscone West Convention Center here in San Francisco.
The USB Type-C standard is gaining rapid support with top-tier laptop and electronics manufacturers by enabling slim industrial designs, easy-to-use connectors and cables, and the ability to transmit multiple protocols and deliver up to 100W of power. The USB Type-C standard's 2.4-mm-high connector plug is significantly smaller than the current 4.5-mm USB Standard-A connector. In addition to the transport of USB signals, DisplayPort and Thunderbolt signals can be delivered over the same connector via the USB Type-C standard's Alternate Mode capability.
