SAN JOSE -- During the Embedded Systems Conference here today, Analog Devices Inc. introduced a single-chip Internet modem, which the company says is the first device to combine TCP/IP protocol stack and modem functionality.
The modem chip integrates TCP/IP (transmission control protocol/Internet Protocol) software from eDevice Inc. of New York. Analog Devices said the modem IC will provide providing Internet connections for a range of systems, known as "light Internet devices." These include portable devices, vending machines, kiosks, and package pickup/drop boxes. A separate processor for protocol stack is not needed because the modem integrates eDevice's SmartStack TCP/IP.
"We see the Analog Devices' Internet modem--powered by SmartStack--bringing entirely new classes of devices and capabilities to the Internet, particularly for remote sensing, data collection, industrial control and remote diagnostics-all with equipment and appliances being able to communicate key information," said Mike Haidar, general manager of the Software & Systems Technology Division at Analog Devices.
Analog Devices, based in Norwood, Mass., believes the modem chip is the first of its kind to address the emerging light Internet device market. "Analog Devices and eDevice share a common vision of the tremendous potential that embedded Internet technology has to offer," Haidar added.
The new chip features Analog Devices' low-power, flash memory-based upgradeable modem, which is based on the ADSST-218X series digital signal processors (DSP). It uses eDevice's SmartStack software containing the TCP/IP stack. Modem rates ranging from V.32bis (14-kilobits/sec.) up to V.90 (56-Kbits/sec.).
"From remote reading of utility meters to image transfers from your digital camera, we envision this compact, ready-to-use modem transforming the light Internet appliance market," said Marc Berrebi, chief executive officer and president of eDevice.
The Internet modem chip is now available. Analog Devices is bundling the modem chip, SmartStack software license, modem code, integrated controller, and data pump device for $18.50 each in quantities of 10,000.
