In April 2000, the company (then NEC Electronics) launched the µPD720100 device, the world’s first USB 2.0-compliant host controller chip and an extensive lineup of other USB devices, and has earned a reputation for delivering dedicated customer service and high-quality products.

USB 3.0 has been developed to address this need by providing the world’s fastest USB transfer speeds of up to 5Gbps of data, which is ten times faster than previous USB 2.0 transfer speeds, while maintaining backward compatibility with the other USB standards.Īs a member of the USB Implementers Forum (USB-IF) since 1996, Renesas Electronics (formerly NEC Electronics) has played a leading role both in defining the USB standards and in developing USB technology.

However, the need to transfer larger and larger amounts of information between PCs and portable electronic devices continued to grow rapidly. Originally USB was designed as an interface for relatively low-speed computer peripherals, such as mice and keyboards.

USB is an interface standard used in a wide range of electronic devices including PCs, digital home appliances, and PC peripherals. In addition, the two-port hub controller delivers industry-leading small power consumption at approximately 5 milliwatts (mW) in low-power mode and approximately 350mW during USB 3.0 operation. The two-port hub controller employs a quad flat no-lead (QFN) package, which is presently the industry-leading small package for USB 3.0 hub controller chips and integrates a voltage step-down regulator equivalent to that of existing hub controllers as well as peripheral components required for rapid charging of tablets, smartphones, etc. The addition of the two-port hub controller (µPD720211) supports designs with tighter space and cost budgets while expanding the USB 3.0 connectivity to utilize the increasing number and performance of USB 3.0 peripherals devices available in the market. Each of these ports is fully backward compatible with all previous versions of USB LS (Low-Speed) / FS (Full-Speed) / HS (High-Speed) / SS (SuperSpeed) operation.Īdding a new two-port hub controller to the lineup alongside Renesas’ world’s first certified USB 3.0 four-port hub controller (part number µPD720210) increases system designers’ options for USB 3.0 hub expansion with products such as PCs, tablets, display monitors, docking stations (function expansion units that connect to notebook PCs), and digital TVs. The controller provides two downstream USB ports.

The µPD720211 is a two-port USB 3.0 hub controller, which complies with the Universal Serial Bus 3.0 Specification and is compatible with Renesas’ industry-standard host controllers. Renesas contributed to the USB-IF certification tests, providing the organization with the host controller products as the platform for other USB 3.0 device certification. In May 2009, Renesas Electronics (then NEC Electronics) introduced the industry’s first USB 3.0 xHCI host controller and, only after four months of its release, the company became the world’s first to earn the “Certified SuperSpeed USB (USB 3.0)” certification from the USB-IF, and also started mass production of the uPD720200 host controller. In April 2000, the company (then NEC Electronics) launched the uPD720100 (the world’s first USB 2.0-compliant host controller chip), the uPD720110, (the world’s first USB 2.0-compliant hub controller chip) and an extensive lineup of other USB devices, and has earned a reputation for delivering dedicated customer service and high quality.
