The R9J02G012 supports USB Power Delivery Rev. 3.0 (USB PD 3.0) and USB Type-C™ Authentication Rev 1.0, which enables device-to-device authentication.
 
The demand for fast-charging mobile devices is growing, driving increased demand for high-power DC power delivery (e.g., 100W). Previously, system manufacturers implemented proprietary fast-charging methods using USB Micro-B connectors. However, with recent smartphone charging/battery incidents, it is critical to offer a safe ecosystem of USB PD-compatible products. The USB Implementers Forum (USB-IF) has standardized the following specifications to provide open, unified, and interoperable technologies to meet these market needs:
 
1. USB Type-C Rev 1.2 Specification: For simpler and easier physical connection of cables, chargers, and devices
2. USB Power Delivery Rev 3.0 Specification: For higher power delivery protocols with additional performance, security, and upgrade features such as PD firmware updates
3. USB Type-C Authentication Specification Rev 1.0: For device-to-device authentication that allows system manufacturers to implement additional charging policies for high-reliability, trusted charging over USB Type-C
 
As a supporting member and board member of the USB Implementers Forum, Renesas has adopted all three standards. The new R9J02G012 is a small, flexible-package USB PD controller for controlling USB Type-C ports on any USB PD device. All ports connecting to these USB PD devices with the R9J02G012 will be able to electronically verify and trust their authenticity based on the certificates and public key infrastructure (PKI) defined in the USB Type-C Authentication Specification. This mechanism allows system manufacturers to implement policies to examine the genuine origin of connected PD devices, such as cables and chargers, before high-power charging (e.g., 20V at 3A) is performed.
 
 
Main features of the R9J02G012:
1) Supports the new USB PD Rev 3.0 standard and the USB Type-C Authentication Rev 1.0 standard for device-to-device authentication
The R9J02G012 provides support for USB PD 3.0 and USB Type-C authentication to identify counterfeit or genuine devices. Leveraging over 30 years of experience supplying secure microcontrollers (MCUs), Renesas has incorporated highly tamper-resistant and information management technologies to prevent MCU security attacks. Renesas has adopted these technologies for the R9J02G012.
 
2) It implements USB PD 3.0 and USB Type-C authentication standards in a single, compact package, reducing the board mounting area to less than 50 percent of that of the existing Renesas device
The R9J02G012 integrates support for both USB PD 3.0 and USB Type-C authentication standards into a single package, whereas previously each required a separate chip. It is available in an easy-to-mount QFN package as well as the more compact BGA package, reducing the mounting area on cables or electronic devices. The board mounting area is less than 50 percent of that required when using the existing Renesas R9A02G011.
 
3) Supports PD firmware (PDFU) updates in accordance with USB Rev. 3.0 specification
The R9J02G012 also supports the Power Delivery Firmware Update Specification (PDFU), Revision 1.0. This optional PD feature is an open standard that allows device firmware updates via a USB Type-C cable.
 
 Availability
Mass production is scheduled to begin in early January 2018.
 
Renesas plans to expand its range of reference designs for applications such as USB Type-C power banks and mobile batteries by combining the R9J02G012 with electrical products from Renesas and Intersil Corporation, which Renesas acquired in February 2017. With the introduction of the R9J02G012, system builders can easily construct a reliable power charging ecosystem of USB PD products based on USB PD and USB Type-C authentication standards.
