Mobile controllers host SuperSpeed USB 3.0
Along with every other portion of the embedded landscape, USB peripherals now require higher-speed interfaces to handle the escalating data rates and increased video content. As a result, Renesas Electronics Corporation recently introduced two new SuperSpeed Universal Serial Bus (USB 3.0) xHCI host controllers that feature faster data transfer speeds and reduced power consumption for mobile electronic devices such as tablet computers and digital televisions. SuperSpeed USB 3.0 was developed to increase the data transfer rate up to 5Gbps, to decrease power consumption, and to be backwards-compatible with USB 2.0. The new µPD720201 and µPD720202 host controllers are available in smaller 7 or 8 mm square QFN package sizes, and include several technologies to reduce power consumption and suppress current leakage when in low-power mode. This has reduced power consumption in low-power mode to 4.5 mW, a reduction of 90 percent compared with existing products. Samples of the four port µPD720201 and two port µPD720202 host controllers are available now, priced at $20 and $10, respectively. Mass production is scheduled to begin in September 2011.
