Introduction
1 Introduction
1.1 General Description
WiReach BK is a secure serial-toWireless LAN device server module that
also acts as a bridge to connect serial
devices to 802.11b/g Wireless LANs. It
™
includes the iChip CO2144 IP
™
Communication Controller chip and
Marvell 88W8686 WiFi chipset. It is
packaged in RoHS-compliant ultra-slim
form factor and uses an industry
standard pin-out.
WiReach BK offers much more than
many other device servers on the
market. It acts as a security gap between
the application and the network;
supports up to 10 simultaneous
TCP/UDP sockets; two listening sockets;
a web server with two websites; SMTP
and POP3 clients; MIME attachments;
FTP and TELNET clients, and
™
SerialNET mode for serial-to-IP
bridging.
WiReach BK supports the SSL3/TLS1
protocol for secure sockets, HTTPS and
FTPS, WEP, WPA and WPA2 WiFi
encryption.
WiReach BK minimizes the need to
redesign the host device hardware. It
easily inserts into headers on the host
PCB and connects to an external
antenna. Minimal or no software
configuration is needed for WiReach BK
to access the Wireless LAN.
™
Connect One’s high-level AT+i API
eliminates the need to add WiFi drivers,
security and networking protocols and
tasks to the host application. The AT+i
SerialNET operating mode offers a true
plug-and-play mode that eliminates any
changes to the host application.
WiReach BK firmware – the IP stack and
Internet configuration parameters – are
stored in an external flash memory. The
module is power-efficient: the core
operates at 1.2V, while I/Os operate at
3.3V. Power Save mode further reduces
power consumption.
1.2 Hardware Description
Size: 46.2 x 25.4 x 5.0 mm
(46.2 x 25.4 x 6mm with shielding option)
Core CPU: 32-bit RISC ARM7TDMI, lowleakage, 0.13 micron, running at 48MHz
Operating Voltage: +3.58V+/-5%
Operating Humidity: 90% maximum
(non-condensing)
Operating Temperature Range:
-20° to 75°C (-4° to 167°F)
Power Consumption:
Transmit – 250mA @16dbm
235mA @12dbm (typical)
Receive – 190mA (typical)
Power Save mode – 8mA
RF Connector: U.FL of Hirose
 Connector: Low profile 70 pin (Molex
#53748-0708)
 Host Interface: TTL Serial and USB
device.
RoHS-compliant; lead-free
1.3 Performance
Specifications
Host Data Rate: up to 3Mbps in serial
mode

Typical Applications
3 Typical Applications
Adding IP communications over WiFi to serial embedded devices.
Adding SSL security to M2M solutions.
WiReach BK supports several operational modes:

SerialNet
Serial to WiFi Bridge - allowing transparent bridging of Serial over
WiFi, using a 3Mbps fast UART. This is a true plug-and-play mode that eliminates
any changes to the host application.

PPP modem emulation – allowing existing (i.e. modem) designs currently using
PPP to connect transparently over WiFi.

Full Internet Controller mode – allowing simple MCU to use the WiReach BK’s rich
protocol and application capabilities to perform complex Internet operations such as
E-mail, FTP, SSL, embedded Web server and others. It also acts as a firewall,
providing a security gap between the application and the network.
