Connect One
1 Introduction
iChip™ CO2064, CO2128 and CO2144
are full-featured programmable IP
Communication Controller™ chips that act
as coprocessors to offload security and IP
connectivity tasks from any host
processor. They are ideal for enabling
devices to achieve secure, high-speed
throughput and access to IP networks via
10/100BaseT LAN or 802.11b/g wireless
LAN, and cellular or dial-up modems.
Typically only one man-month is needed
for hardware engineering and adding IP
connectivity commands to the host
application.
While the CO2128/CO2144 include a
complete set of features, the CO2064
uses an open software architecture that
enables users to select and program
different firmware flavors, each providing a
unique subset of Internet protocols and
features.
The CO2128/CO2144 firmware supports
up to 10 simultaneous active TCP/UDP
sockets and two listening sockets; HTTP,
SMTP, MIME, POP3, FTP and TELNET
clients; a web server with two websites:
one for configuring the CO2128/CO2144
and one for the application; and serial-to-
IP bridging.
The CO2064 comes in two firmware
flavors:


Flavors can be quickly interchanged
simply by sending an AT+i™ command.
iChip CO2064/CO2128/CO2144 Data Sheet
General Description
Flavor A offers 10 active TCP/UDP
sockets and two listening sockets;
sending ASCII e-mails; sending and
retrieving data from an FTP server,
and serial-to-IP bridging in SerialNet™
mode.
Flavor B supports one secure
TCP/UDP socket plus 9 non-secure
sockets.
Preliminary
Security features in the CO2064 include
the hardware implementation of a random
number generator, SHA-1 secure hash
accelerator, AES-128/256 encryption
accelerator, 3DES, SSL3/TLS1, RSA,
RC-4 and MD-5. The CO2128 includes, in
addition to the above, WEP, WPA, and
WPA2 encryption for WiFi.
CO2064 loads its firmware and Internet
configuration parameters either from an
external SPI flash memory, or accepts it
from the host via one of the supported
interfaces. Firmware can be updated
locally via RS232.
CO2128/CO2144 load their firmware from
an external EBI flash memory. Firmware
can be remotely updated via sockets, FTP
or HTTP.
All three iChips include a 32-bit
ARM7TDMI RISC processor and 256KB of
embedded high-speed SRAM. Basic
peripherals for all models include USB v.
2.0 full-speed host and device port;
10/100BaseT Ethernet MAC with MII/RMII,
USART and SPI interfaces.
Both CO2064 and CO2128/CO2144
feature Sleep mode for energy savings.
The iChips come in a 64-pin (CO2064),
128-pin (CO2128) or 144-pin (CO2144)
LQFP RoHS-compliant package.

Connect One‘s AT+i protocol eliminates
the need for Internet programming and
minimizes changes to the host application,
while the SerialNET serial-to-IP bridging
mode eliminates the need for any change
to the host application. AT+i commands
are intercepted by iChip, which puts the
host device into Internet mode.
