Functional Description
3 Functional Description
3.1 Overview
Connect One’s iChip LAN Internet Controller is an integrated, firmware-driven, self-
contained Internet engine that is available in a 68-pin PLCC package. iChip LAN accepts
simple ASCII commands from a host CPU via a serial communication channel and
manages an Internet communication session through an Ethernet LAN connection.
For 10BaseT Ethernet applications, iChip LAN CO561AD-L includes the firmware and
pin-out necessary to drive external Crystal LAN CS8900A (3.3-volt or 5-volt) or Realtek
RTL8019AS (5-volt) 10BaseT Ethernet controllers. iChip LAN supports commands to
communicate via TCP and UDP sockets; to send and receive Email, Web and WAP
pages/files, utilize FTP and Telnet; or to serve as a serial-to-Internet router.
iChip LAN CO561AD-L contains non-volatile flash memory to store its firmware and
Internet-related configuration parameters. Remote firmware and parameter updates are
supported through the local host link, by Email or by using a Web browser.
3.2 Technical Specifications
3.2.1 General
iChip LAN constitutes a complete Internet messaging solution for non-PC embedded
devices. It acts as a mediator device to completely offload the host processor of Internet-
related software and activities. An industry-standard asynchronous serial link connects
iChip LAN to the host processor. Programming, monitoring and control are fully
supported using Connect One’s AT+i extension to the standard AT command set.
3.2.2 Data Rates
CO561AD-L supports standard baud rate configurations from 2,400 bps up to 115,200
bps on the host asynchronous serial communications channel. The default baud rate may
be changed permanently by using the AT+iBDRF command. Auto baud rate setting is
supported for all baud rates.
3.2.3 Operation
All iChip LAN Internet and parameter operations are controlled by AT+i commands.
3.2.3.1 Command Mode
iChip LAN commands are implemented using the AT+i command set. Command flow
exists only on the host serial channel between the host and iChip LAN.
