Description
General
iChip™ CO710AG and iChipSec™ CO711AG
Internet Controllers™ are high-performance,
firmware-based intelligent peripheral devices
that provide Internet connectivity solutions for a
wide range of embedded devices. The firmware
provides Internet communication via 10BaseT
and 10/100BaseT Ethernet LANs, 802.11b
Wireless LAN with WEP or WPA security, dial-
up and wireless modems. CO710AG/CO711AG
are packaged in an RoHS compliant 121-ball
uBGA form factor. CO710AG/CO711AG
firmware is remotely updateable via sockets,
FTP/HTTP server or the Web browser.
CO710AG/CO711AG are designed for high-
bandwidth applications. The host interface and
33/66 MHz clock support 230 kbits/second in
Serial mode. The CO710AG/CO711AG also
feature a Power Save mode for saving energy.
CO710AG/CO711AG operate in the industrial
temperature range.
As an embedded, self-contained Internet engine,
iChip acts as mediator device between a host
processor and an Internet communications
platform. By completely offloading Internet
connectivity and standard protocols, it relieves
the host from the burden of handling Internet
communications. From the perspective of a host
device, the complexity of establishing and
maintaining Internet-related sessions are reduced
to simple, straightforward commands that are
entirely dealt with within the domain of
iChip/iChipSec.
A serial bus interfaces iChip CO710AG/
iChipSec CO711AG to a device’s host processor
via an on-chip UART. CO710AG/CO711AG
also directly interface an Ethernet controller, a
WiFi controller or a serial data modem, through
which they support independent communications
on the Internet via a dial-up or wireless ISP
connection. In addition to supporting dial-up
modems, CO710AG/CO711AG also support
AMPS, CDMA, CDMA2000, CDPD, GPRS,
GSM, IDEN and TDMA cellular modems.

1 Introduction
iChip CO710AG/iChipSec CO711AG Data Sheet
CO710AG/CO711AG support 10BaseT Ethernet
LANs with the addition of an external 16-bit Cirrus
Logic Crystal LAN CS8900A. It also supports
10/100BaseT LANs with the addition of an SMSC
LAN91C111 or ASIX AX88796L Ethernet controller.
802.11b WiFi is supported with an addition of a
PCMCIA or CF Wireless LAN module using the
Prism 2.5/3.0 WiFi chipset. 802.11b/g WiFi is
supported with an addition of an RF module that
supports the Marvell 88W8385 WiFi chip.
CO710AG/CO711AG also support WEP and WPA
security.
Through its host Application Programming
Interface (API), iChip and iChipSec accept commands
formatted in Connect One's AT+i™ extension to the
industry-standard Hayes AT command set. iChip and
iChipSec support several levels of status reporting to
the host. Commands are available to store and
manipulate functional and Internet-related non-volatile
parameter data; utilize TCP and UDP sockets; transmit
and receive textual Email messages; transmit and
receive binary (MIME encoded) Email messages; fetch
HTML web pages; manipulate files and directories via
FTP; maintain Telnet sessions and download
parameter and firmware updates for the host device or
iChip/iChipSec itself. iChip and iChipSec include a
Web server engine that hosts an internal configuration
Web site as well as a customizable application Web
site. iChip and iChipSec also include a WAP server to
host a WAP site.
When the host CPU issues standard AT commands and
the modem platform is selected, iChip/iChipSec gains
direct access to the modem, and automatically operates
in Transparent mode, emulating a direct host-to-
modem environment.
Upon receiving an AT+i command, iChip and
iChipSec operate in Internet mode, controls the
modem or Ethernet controller, and independently
manages standard Internet protocols to transmit and
receive messages. iChip/iChipSec provides all the
necessary procedures to log onto an ISP, authenticate
the user and establish an Internet session.
