Description
The CO561AD-S, iChip™ Internet
Controller™, is part of a family of
intelligent peripheral devices that provide
Internet connectivity solutions to a myriad
of embedded devices. iChip CO561AD-S is
used for dial-up and wireless Internet
connectivity.
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 is
reduced to simple, straightforward
commands that are entirely dealt with within
iChip’s domain.
A serial channel interfaces iChip
CO561AD-S to a device’s host processor via
an on-chip UART. iChip CO561AD-S also
directly interfaces a serial data modem,
through which it supports independent
communications on the Internet via a dial-up
or wireless connection to an Internet
Service Provider (ISP) or direct modem
communications.
iChip CO561AD-S supports AMPS,
CDMA, CDPD, GPRS, GSM, iDEN, and
TDMA cellular modems.
1 Introduction
iChip CO561AD-S Datasheet
Through its host Application Programming
Interface (API), iChip accepts commands formatted
in Connect One's AT+i™ extension to the industry-
standard Hayes AT command set. iChip supports
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 itself. iChip includes a Web
server engine that hosts an internal configuration
Web site as well as a customizable application Web
site. iChip also includes a WAP server to host a
WAP site.
When the host CPU issues standard AT commands,
iChip CO561AD-S allows direct access to the
modem by automatically operating in transparent
mode, emulating a direct host-to-modem
environment. When the host CPU issues AT+i
commands, iChip enters into Internet mode and
controls the modem connection to an ISP. iChip
provides all the necessary procedures to log onto an
ISP, authenticate the user and establish an Internet
session. Upon receiving an AT+i command, iChip
independently manages standard Internet protocols
to transmit and receive data over PPP. iChip also
includes a mode known as SerialNET mode, which
eliminates the need to program the host CPU with
AT+i commands.
