Analog Devices Inc. today announced an Internet modem that it claimed is the first to embed a TCP/IP protocol stack on a single chip.
At the Embedded Systems Conference in San Jose, the chip maker said its device can offer complete Internet connectivity.
The TCP/IP stack was developed and integrated by eDevice Inc., a New York-based developer of low-cost Internet-connectivity technology.
The modem empowers low-cost and portable devices, as well as vending machines, kiosks and pickup/drop boxes, to connect to the Internet over any network that uses the TCP/IP protocol, without requiring a separate processor that contains the protocol stack.
The single-chip modem features Analog Devices' low-power, flash-upgradable modem, based on an ADSST-218X series digital signal processor (DSP) and eDevice's SmartStack Internet-enabling software containing the TCP/IP stack, available with a modem data rate from V.32bis (14,000 bits per second) up to V.90 (56,000 bits/s). It also has an integrated controller, so that a separate microcontroller is not required.
"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, Norwood, Mass.
Haidar said the new ADI Internet modem addresses the emerging "light" Internet device market by giving OEMs the flexibility to connect a wide range of equipment and systems to the Internet for such tasks as information transfer, remote management, control andservicing, and e-mail.
The single-chip modem still leaves room for a client or signal processing application, said Marc Berrebi, CEO and president of eDevice. "OEMs can now design-in powerful Internet access capabilities in an easy-to-integrate, scalable package," he said. "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."
The Analog Devices' Internet modem is currently available. In addition to the ADSST-218X series DSP with the SmartStack TCP/IP stack and the integrated controller, it includes modem code and an intregrated data pump, and is available in a 100-pin package.
Prices for the single-chip modem with the SmartStack TCP/IP stack, software, licenses and a two-chip silicon DAA begin at $18.50 in quantities of 10,000.
