Azzurri Technology has NEC's uPD720100 USB 2.0 host controller.

Azzurri Technology has introduced NEC's uPD720100 USB 2.0 host controller.

The new controller from NEC contains five USB 2.0 ports and has a 32bit 33MHz PCI interface (Release 2.2).

NEC is an industry leader in the field of USB 2.0 and is the first manufacturer to offer solutions that are fully approved to the high speed USB specification.

The uPD720100 completes the USB 2.0 line up from NEC, which includes a five-port hub controller (four downstream ports, one upstream), a PHY chip which connects USB 2.0 to 16bit serial data streams and a USB to IDE bridge, which allows conversion to ATA/ATAPI-4 interfaces.

These products allow designers to interface between USB 2.0 and other system buses.

All NEC USB2.0 controllers are backwards compatible with the older USB 1.x controllers at 40MBit/second but also support the full USB 2.0 speed of 480Mbit/s.

USB 2.0 is ideally suited to the next generation of computing devices and peripherals.

With data rates in excess of those of FireWire and up to 5m cable lengths (longer possible with a hub), USB 2.0 is set to provide a complete solution to all applications requiring a simple interconnection scheme and high data throughput.

It also provides a method of connection legacy products that only support USB1.x, allowing designers to future proof designs and connect to other USB 2.0 equipped devices as they become available.

The uPD720100 is available in 160-pin plastic LQFP and 176-pin plastic FBGA and is available now through Azzurri Technology.
