FCC Statement
NOTICE;
1. The RF module limited to OEM installation ONLY.
The OEM integrator is responsible for the compliance to all the rules that apply to the
product into which this certified RF module is integrated.
2. This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
3. This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
l Reorient or relocate the receiving antenna.
l Increase the separation between the equipment and receiver.
l Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
l Consult the dealer or an experienced radio/TV technician for help.
FCC Caution
Any changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate this equipment. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm between
the radiator & your body.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users, and The
transmitter module may not be co-located with any other transmitter or antenna. As long as 2
conditions above are met, further transmitter test will not be required. However, the OEM integrator is
still responsible for testing their end-product for any additional compliance requirements required
with this module installed.

IMPORTANT NOTE:
In the event that these conditions cannot be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization is no longer considered valid and the
FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such
that 20 cm may be maintained between the antenna and users. The final end product must be labeled
in a visible area with the following:
“Contains FCC ID: XR2WIZFI250”.
The grantee's FCC ID can be used only when all FCC/ IC compliance requirements are met.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user's manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.

802.11b/g/n Wireless LAN WICED Module
STM32F205RGY6 Microprocessor
Introduction
The WM-N-BM-14 wireless WICED module which is a
small size module and consists of a Broadcom
BCM43362 single-chip, a ST STM32F205RG MCU, and
a 2.4G antenna. The WM-N-BM-14 provides for the
highest-level integration, featuring 802.11b/g and
802.11n.
It includes a 2.4 GHz WLAN CMOS power amplifier
(PA) that meets the output power requirements of most
handheld systems. An optional external low-noise
amplifier (LNA) and external PA are also supported.
Along with the integrated power amplifier, the WM-NBM-14 also includes integrated transmit and receive
baluns, further reducing the overall solution cost.
The small size & low profile physical design make it
easier for system design to enable high performance
wireless connectivity without space constrain. This
multi- functionality and board to board physical interface
provides SPI/I2C/I2S/UART interface options.
Hardware WAPI acceleration engine, AES, TKIP, WPA
and WPA2 are supported to provide the latest security
requirement on your network.
For the software and driver development, USI provides
extensive technical document and reference software
code for the system integration under the agreement of
Broadcom International Ltd.
Hardware evaluation kit and development utilities will be
released base on listed OS and processors to OEM
customers.
