iChip mediates the connection between a host device and the Internet, operating as an embedded device server.
A complete, firmware-based hardware and software solution, iChip includes basic and upper-layer Internet protocols and many features that optimise communication over IP-enabled networks, such as security, automatic port reconnect and IP address registration. iChip works with almost all wired and wireless LANs and modems, any host processor and any or no host operating system.
All models feature Connect One’s AT+i protocol, which eliminates the need for Internet programming and minimises changes to the host application. In fact, when using AT+i’s SerialNET mode, no changes to the host application are required at all. The AT+i command set is portable among all iChip models. iChip supports the complete TCP/IP protocol stack and includes upper layer protocols such as SSL3/TLS1.0 SMTP, POP3, MIME, HTTP, WAP, FTP and TELNET. It also includes an onboard Web server and features built-in security in the form of secure sockets, secure upper layer protocols, secure SMTP authentication and MD5 password encryption for the embedded Web server.
iChip is available in several families designed to meet the needs of a wide range of applications. All solutions support TCP/UDP sockets, and most support upper layer protocols and serial-to-IP bridging via AT+i’s SerialNET operating mode.
The CO2064 includes 10/100BaseT Ethernet MAC; USB host and device; SSL3/TLS1 encryption and UDP acceleration in hardware; routing; optional soft modem; tamper protection; one two-wire, one SPI and one USART interface. It supports 802.11b/g WLANs, 10/100BaseT LANs, dial-up and wireless modems. The CO2128/CO2144 match these features, plus an extra SPI and USART, high-speed parallel bus and external bus interfaces.
