USB 2.0 IC combines host and peripheral control

The uPD720150 allows direct connection to a wide variety of popular embedded CPUs, thus saving space and reducing costs.

Available now from Gleichmann Sunrise, the NEC Electronics uPD720150 integrated USB 2.0 controller enables data transfers at rates up to 480Mbit/s.

The newest member of the EcoUSB series combines on a single chip functions that formerly required separate USB host and USB peripheral controller ICs.

By means of appropriate register settings, the two USB ports can be operated in four different configurations: one host port, two host ports, one peripheral port or one host port and one peripheral port, whereby the number of ports can be increased by connecting an external hub from NEC Electronics.

Further features of the uPD720150 are the many, hardware-implemented, basic USB functions, which significantly reduce the additional software effort.

For example, the uPD720150 enables automatic audio and video data transfers.

Thanks to a 16bit CPU interface with selectable timing control modes, the uPD720150 allows direct connection to a wide variety of popular embedded CPUs, thus saving space and reducing costs.

Low power technology, developed by NEC Electronics specifically for the EcoUSB series of USB products, also guarantees a high flexibility of use.

For example, by completely stopping the clock when USB functions are not in use.

Furthermore, by means of an integrated voltage regulator, the internal supply voltage can be reduced from 3.3 to 1.5V.

The uPD720150 is available now in sample quantities.

Volume production is planned for September 2008.
