Description
The iChip™ CO120SQ Internet
Controller™ is a high-performance,
firmware-based intelligent peripheral
device that provides Internet
connectivity solutions for a wide range of
embedded devices. The firmware
provides IP communication via a
modem, LAN controller, or WiFi CF
adapter. CO120SQ is packaged in an
RoHS-compliant TQFP 64-pin form
factor.
Its serial host interface supports
throughput up to 250 kbits/second.
CO120SQ also features a Power Save
mode and will include a Sleep mode for
energy conservation. CO120SQ
operates in the industrial temperature
range and is RoHS-compliant.
CO120SQ is powered from a single 3.3-
volt supply and incorporates an internal
1.8-volt converter for its CPU core.
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 iChip’s domain.
1 Introduction
iChip CO120SQ Data Sheet
A serial or USB
interface iChip to a device’s host processor.
iChip accesses the Internet using one of
three communication links: modem (wired or
wireless), 10/100BaseT LAN (with an
additional Ethernet controller), or 802.11b
Wireless LAN (with an external compact flash
adapter that uses the PRISM 2.5/3.0 802.11b
WiFi chipset).
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; to support up to
10 simultaneous TCP and UDP sockets to
send and receive data over the Internet; to
support up to two listening sockets; to send
email; to open and close FTP files; to fetch
HTML web pages, and to perform serial-to-IP
routing.
iChip CO120SQ is the first in a new series of
programmable chips that feature an open
architecture. You can choose from a variety
of firmware versions (flavors) that can be
downloaded from Connect One’s Web site.
Each firmware flavor defines a different
functional subset. Flavors also define
different pin-out assignments to support
separate communication links: cellular or
dialup modem, 10/100BaseT LAN or 802.11b
WiFi. The firmware flavors are downloaded
into iChip using its factory-installed non-
volatile Boot Loader. By default, CO120SQ is
shipped from the factory with only the Boot
Loader pre-installed.
