Description
CO661AL-D iChip Plus™ Internet
Controller™ is part of a family of intelligent
peripheral devices that provides Internet
connectivity solutions to a myriad of
embedded devices. iChip Plus CO661AL-D
supports dial-up, wireless and 10BaseT or
10/100BaseT Ethernet 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 are
reduced to simple, straightforward
commands that are entirely dealt with within
iChip Plus’s domain.
A serial channel interfaces iChip Plus
to a device’s host processor via an on-chip
UART. iChip Plus can also interface a host
processor through an 8-bit parallel
connection with some glue logic. iChip Plus
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, iDEN,
CDPD and AMPS cellular modems.
10/100BaseT Ethernet LANs with an
additional Ethernet controller.
Available only for 3.3-volt operation,
CO661AL-D includes features not available
on iChip Plus CO561AD-D. It includes a
host interface that supports 230 kbps
bandwidth in serial mode and will support
500 Kbytes burst with up to 400 Kbytes
sustained bandwidth in Parallel mode.
iChip Plus also supports 10BaseT or
1 Introduction
iChip Plus CO661AL-D Datasheet
CO661AL-D features power save modes and will
have an extended temperature range version.
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 and 10/100BaseT
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.
