MOUNTAIN VIEW, Calif. -- NetChip Technology Inc. here today announced a controller designed to meet the specifications for the new, high-speed Universal Serial Bus (USB) 2.0 standard.
Targeted for digital audio players, printers, mass storage devices, and scanners, the NET2270 controller from NetChip has a data transfer rate of up to 480-megabits-per-second--about 40 time faster than the chip-level products based on the USB 1.1 standard.
"Most of the early adopters of USB 2.0 are manufacturers of printers, scanners and mass storages devices," said Robert Wong, vice president of sales and marketing for NetChip. "The main objective of the NET2270 is to help OEMs get to market in the quickest time possible."
The NET2270 consists of several components on the same device, including a 16-bit local CPU bus interface, a USB 2.0 serial interface engine, 4 programmable endpoints, up to 2-Kbytes of selectable double-buffered FIFO memory arrays, and an analog USB 2.0 transceiver.
The chip also has a CPU access cycle time of less than 35-ns. The built-in, double-buffered FIFO memory eliminates data latency, while the chip's split bus architecture supports simultaneous CPU and DMA operations.
The device offers a simple interface to the local CPU. It comes with comes with three register addressing modes, enabling the device to interface to any CPU on the market.
Based on a 0.35-micron process, the NET2270 is manufactured on a foundry basis by Japan's NEC Corp. Housed in a 64-pin TQFP package, the chip is $9 in large volumes. The device will begin sampling in December, with production slated for the first quarter of 2001.
To help OEMs and software designers, NetChip also offers a complete development kit. Called the NET2270PCI-RDK, the kit includes a PCI board, the NET2270, and software. It will also be available in December.
