Description
The CO561AD-D iChip Plus™ Internet
Controller™ is a low-cost intelligent
peripheral device that provides Internet
connectivity solutions to a myriad of
embedded devices. iChip Plus supports dial-
up, wireless and 10BaseT Ethernet LAN
Internet connectivity.
As an embedded, self-contained Internet
engine, iChip Plus 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 Plus’s domain.
A serial bus interfaces iChip Plus to a
device’s host processor via an on-chip
UART. iChip Plus also directly interfaces a
serial data modem, through which it
supports independent communications on
the Internet via a dial-up ISP connection. In
addition to supporting dial-up modems,
iChip Plus also supports CDMA, TDMA,
GSM, GPRS, CDPD, iDEN and AMPS
wireless modems. Furthermore, the iChip
Plus directly interfaces an Ethernet
controller to gain access to the Internet
through a standard LAN.
1 Introduction
iChip CO561AD-D Datasheet
Through its host Application Programming
Interface (API), iChip Plus accepts commands
formatted in Connect One's AT+i™ extension to
the industry-standard Hayes AT command set.
Commands are available to store and manipulate
functional and Internet-related non-volatile
parameter data; transmit and receive textual Email
messages; transmit and receive binary (MIME
encoded) Email messages; serve and fetch HTML
web pages; manage FTP and Telnet transactions;
act as a dynamic Web server; manipulate TCP and
UDP sockets; and download parameter and
firmware updates for the host device or iChip Plus
itself. iChip Plus supports several levels of status
reporting to the host. When the host CPU issues
standard AT commands, iChip Plus gains direct
access to the modem and automatically operates in
transparent mode, emulating a direct host-to-
modem environment (when the modem platform is
selected).
iChip Plus supports 10BaseT Ethernet LANs and all
serial data modems that support the AT command
set. A dedicated AT+i command enables switching
iChip Plus between LAN or modem mode.
Upon receiving an AT+i command, iChip Plus
operates in Internet mode, controls the modem or
Ethernet controller, and independently manages
standard Internet protocols. iChip Plus provides all
the necessary procedures to log onto an ISP,
authenticate the user and establish an Internet
session.
