NEC Electronics Corporation yesterday announced the availability of second-generation USB 2.0 hub controllers designed to deliver very low power consumption.
The multi-port uPD720112 and uPD720113 controllers, produced by NEC's 0.25-micron process technology, reduce power consumption by up to 60 per cent compared to the company's first-generation products.
The devices will be targeted at devices such as docking stations and hub boxes.
"The new hub controllers are an important addition to our USB product family," said Hiroshi Nakashiba, vice president and general manager, broadband LSI technology strategic business unit, NEC Electronics America.
"The power savings and multi-port capabilities provided by our new controllers make them attractive for a range of applications, including hub devices that can take advantage of the bus-powered capability of our uPD720112 controller.
The uPD720112 hub controller provides four configurable downstream ports, including two bus-powered ports. The uPD720113 provides seven configurable downstream ports.
Both products offer data transfer rates up to 480Mbps, and support the 'split transaction' scheme for full-speed and low-speed USB devices.
Production quantities of the uPD720112 and uPD720113 hub controllers are scheduled to be available in May.
