3.1 Reference Documentation
For information on technical details of the WirelessUSB LR
2.4-GHz DSSS Radio SoC such as register settings, timing,
application interfaces, clocking, and power management, refer
to the data sheet of the CYWUSB6935 Radio SoC.
3.2 Applications Support
The CYWM6935 is available as a reference design, complete
with PCB layout files, schematics, and a bill of materials. The
CYWM6935 can be used with the CY3635 WirelessUSB N:1
sensor development kit, and the CY3632 WirelessUSB LS
development kit via a 1 x 14 adaptor board.
www.DataShee4t4.U0.com Module Certification Details
4.1 Eligibility Requirements for Regulatory Mod-
ule Approval
The CYWM6935 LRTM Radio Module is a device that transmits
and receives radio signals in accordance with the spectrum
regulations for the 2.4-GHz unlicensed frequency range.
Regional regulatory agency approval may be required to
operate CYWM6935 throughout the world.
Cypress Semiconductor Corporation has obtained regulatory
approvals for the CYWM6935 to be used in specific countries.
CYWM6935 was approved under the “Modular Approval (MA)
Grant”. This certification represents a significant cost savings
to the OEM.
The MA Grant provides that device manufacturers who incor-
porate CYWM6935 as tested and approved can be relieved
from having to perform the Radio Regulatory certification
portion of the respective agency certification.
The MA Grant is valid only in countries[1.] that recognize the
MA Grant certification process; the USA, Canada, Belgium,
Denmark, France, Finland, Germany, Italy, Netherlands,
Spain, Sweden, UK.
In order to be able to take advantage of Cypress’s modular
certification in a end product, the following must be ensured:
1.) Correct Application
2.) Correct Installation
3.) Correct labeling
4.1.1 Correct Application:
There are three types of application considered for wireless
modules and the LR has been verified to work with all three
application types at pre-certified power output levels.
However, other usages are possible with re-certification. The
application types are defined as follows
4.1.1.1 Fixed Application:
Module is in a permanent location and has atleast 2m
separation from the human body.
4.1.1.2 Mobile Application:
Module can be relocated and will have atleast 20cm
separation from the human body.
Note:
1. This list is as of march 2006. Please talk to your local Sales person for the
current list.
Document #: 38-16013 Rev. *A
4.1.1.3 Portable Application:
Module can be relocated and will have less than 20cm
separation from human body.
4.1.2 Correct Installation:
• Modules cannot be modified in any way
• Modules must be used only in the operating range specified
in the datasheets
• Modules cannot be co-located within 20cm of another inten-
tional radiator in the system
• Must guarantee that end user cannot easily change antenna
Note: Sidestepping these requirements is possible with
additional testing and/or recertification. However, modular
approval would no longer apply.
4.1.3 Correct Labeling:
If end device containing a WirelessUSB LR Module will be sold
or used in the USA, the enclosure of the product must display
a label with the following basic elements:
CYWM6935
Contains FCC ID: R8KUGWW2USHN33A
If end device containing a WirelessUSB LR Module will be sold
or used in Europe, the enclosure of the product must display
a label with the following basic elements:
CYWM6935
0122
If end device containing a WirelessUSB LR Module will be sold
or used in Canada, the enclosure of the product must display
a label with the following basic elements:
CYWM6935
This product contains Cypress WirelessUSB module
Canadian Cert No IC: 5125A-UGWW2US
As of March 2006, Japan does not recognize the “Modular
Approval” certification. Regulatory certification for Japan
(TELEC) must be acquired through typical approval proce-
dures. These approvals are the sole responsibility of the OEM.
Note:
Even with modular approval, the end device still has to be
tested for digital emissions compliance with all agencies as an
electronic device. The modular approval only eliminates the
need to test for compliance on RF transmissions.
4.2 User Guide Information
Electronic device manufacturers using Cypress’s Modular
Approval are required to follow the below mentioned labeling
