INTERNET MODEM

The iChip Internet Modem Module (IMM) is a streaming socket technology-based Internet modem. It combines a true single-chip embedded modem with the iChip TCP/IP/PPP hardware protocol stack, thus offering complete Internet connectivity. The modem targets low-cost and portable devices for test and measurement, data collection and remote sensing, as well as other field-deployed devices that must be connected to the Internet via a dial-up network using the TCPBYPPP protocol.

Streaming socket technology uniquely manages multiple TCP sockets over a single communications channel, such as a serial port. In addition, each socket can be deployed for virtually any Internet protocol. This makes it suitable for a wide range of Internet applications while ensuring code and design data reusability. It also allows a TCP socket to be used without requiring knowledge of data lengths. It is ideal for memory, code size, or other resource-constrained systems.

The IMM features S7600A TCP/IP/PPP hardware protocol stack and a 73M290lC fast-connect modem. It is also socket-compatible with the Conexant SocketModem family of data link modems, thus providing a compact, industry-standard form factor and a direct upgrade path for systems currently being deployed with SocketModem data link-only modems.

The Internet Modem Module evaluation kit is now available at a price of $99. The IMM reference design and license to use the streaming socket technology is also currently available at no charge.
