Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today announced the Universal Serial Bus (USB) Power Delivery (PD) controller (part number R9A02G011, successor of µPD720250) that supports USB Power Delivery 3.0. The new USB PD controller supports not only PC and smart phone applications, but also a wide range of devices using direct current (DC) power, including PC peripherals, AC adapters, projectors, robots and other consumer electronics.
The USB Power Delivery specification from USB Implementers Forum (USB-IF) increases the maximum rating of USB charging from 7.5 W (based on the earlier USB specifications) to 100W with different voltage levels up to 20V at 5A. With the arrival of USB PD and the new USB Type-C™ connector, the usage models of USB charging and data communication are expected to increase significantly. The USB Power Delivery 3.0 specification adds features such as enabling authentication message exchange for USB Type-C to USB Type-C cables. For device designers and system developers, adopting the Renesas R9A02G011 controller in their devices will make it possible to develop systems with faster charging times. In addition, the new controller reduces system development costs by simultaneously supporting data communication and power supply over a single USB cable, and simplifying many connections existing between devices.
With the rapid demand growth for devices using USB charging, the potential for sub-standard and non-compliant USB accessories (e.g., cables) entering the market increases substantially. The need for identifying non-compliant USB products becomes critically important, particularly for the high-power charging designs based on the USB PD. As a long-time, key supporter of USB-IF, Renesas supports the requirements of the new USB Power Delivery 3.0 specification.
Renesas will also deliver R9A02G011-based solutions combining Renesas’ authentication processor and advanced power supply control technologies. These solutions will be the building blocks to support the safety, security, efficiency and robustness needs for the upcoming USB PD eco-systems.
The R9A02G011 supports both USB Power Delivery 3.0 and USB Type-C™ specifications. This new device includes integrated on-chip flash ROM, oscillator and power-on reset circuits, and other features, allowing the number of external components to be reduced significantly. As a result, the new USB PD controller can be used in a wide range of applications with limited board space. The R9A02G011 contributes to safe and secure structures in USB PD power supply, supporting systems as well as reduced development costs. It is provided in a small 32-pin QFN package (other package products are under consideration.)
