Description
The CO661AL-L iChip LAN™ Internet
Controller™ is part of a family of intelligent
peripheral devices that provides Internet
connectivity solutions to a myriad of
embedded devices. iChip LAN CO661AL-L
is used for 10BaseT or 10/100BaseT
Ethernet LAN Internet connectivity.
As an embedded, self-contained Internet
engine, iChip LAN 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 LAN’s domain.
A serial channel interfaces iChip LAN
to a device’s host processor via an on-chip
UART. iChip LAN can also interface a host
processor through an 8-bit parallel
connection with some glue logic. iChip
LAN supports 10BaseT Ethernet LANs or
10/100BaseT with an additional Ethernet
controller.
Available only for 3.3-volt operation,
CO661AL-L includes features not available
on CO561AD-L. It includes a host interface
that supports 230 kbps bandwidth in serial
mode and will support 500 Kbytes/Sec burst
with up to 400 Kbytes/Sec sustained
bandwidth in parallel mode. CO661AL-L
features power save modes and will have an
extended temperature range version.
1 Introduction
iChip LAN CO661AL-L Datasheet
Through its host Application Programming
Interface (API), iChip LAN accepts commands
formatted in Connect One's AT+i™ extension to
the industry-standard Hayes AT command set.
IChip LAN 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 LAN
itself. IChip LAN includes a Web server engine that
hosts an internal configuration Web site as well as a
customizable application Web site. iChip LAN also
includes a WAP server to host a WAP site.
In addition, iChip LAN includes a communication
mode known as SerialNET mode, which eliminates
the need to program the host CPU with AT+i
commands. SerialNET allows direct host-to-
Internet connectivity without requiring any
reprogramming of the host application.
