USB Device Controller Targets Imaging And Storage Devices

A simple and quick upgrade path to high-speed USB 2.0 is provided with the NET2270, the company's second USB2.0 peripheral device controller targeted at imaging and storage devices such as printers, scanners, mass storage products, and digital audio players.
The chip has a 16-bit local CPU bus interface, a high-speed USB 2.0 serial interface engine, four programmable endpoints, up to 2 KB of selectable double-buffered FIFO memory arrays, and an integrated analog USB 2.0 transceiver. Interfacing to the chip's local CPU interface is simple. A designer needs only a few control signals to access the streamlined registers of the chip. In a 64-pin TQFP, the chip is priced at $9.00 each.
