Incorporating into a miniature 10x10mm LFBGA 144-ball package, the controller is designed for use in wireless LAN and all cellular design, making it ideal for applications such as automotive, remote monitoring, and medical devices where secure, robust connectivity is essential. Multiple power-save modes increase battery life for these mobile devices.
The CO21244 offers a full suite of Internet protocols and applications, enabling immediate and full”featured connectivity for M2M solutions. Since CO2144 works as a coprocessor, developers do not need to program or write code that controls connectivity or application security.
Instead, the logical interface between the host application and CO2144 is Connect One's AT+i Protocol, a text-based API that enables fast and easy implementation of Internet networking and security protocols.
AT+i requires no programming expertise on the part of the designer. Only a few hours are required to create full-featured Internet access, including TCP sockets, SSL encryption, routing, e-mail, and file transfers.
CO2144 brings Internet security commonly found only in PCs to embedded devices. It serves as a “firewall on a chip,” protecting the embedded device from the Internet attacks.
It also includes the latest WLAN (64/128-bit WEP, WPA/WPA2 enterprise) and Internet (AES-128/256, SHA-128/192/256, 3DES; SSL3/TLS1 protocol for a secure client socket session) encryption algorithms for complete, end to end encryption support.
According to Ariel Shulman, Connect One vice president of sales, developers wanting to add a web user interface can use CO2144's embedded HTTP/HTTPS web server. By uploading the application website into the CO2144 and using simple AT+i commands, the embedded device instantly offers a modern WebUI to the end user.
The chip supports seamless WLAN roaming, multiple SSID and WPA2-Enterprise authentication commonly required in large scale WLAN deployments. As well, it supports dial-up and LAN wired networks, as well as 802.11b/g WLAN and practically all cellular solutions (e.g. CDMA, GSM, GPRS, UMTS). CO2144 includes a 10/100BaseT Ethernet MAC and supports 10 simultaneous TCP/UDP sockets; two listening TCP sockets; SMTP, MIME, POP3, FTP/Secure FTP, Telnet, and HTTP/HTTPS clients; and SerialNet mode for serial-to-IP bridging.
The CO2144 operates at an industrial temperature range of -40 to 85 degrees Centigrade (-40 to 185 degrees Fahrenheit) and is RoHS-compliant.
CO2144 is available now and is priced at under $7 for large volume customers. The II-EVB-630 evaluation board ($575 list price) provides an easy environment for developing applications and testing CO2144/2128. To learn more, go to www.connectone.com.
