Cypress Semiconductor Corp. announces that its 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).
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.
