CYWM6935 preliminary document #: 38-16013 rev. *a page 2 of 8 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. 4.0 module certification details 4.1 eligibility requirements for regulatory mod- ule approval the CYWM6935 lr tm 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 certificat ion represents a significant cost savings to the oem. the ma grant provides that de vice 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 applic ation considered for wireless modules and the lr has been verified to work with all three application types at pre-cert ified 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. 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 recert ification. 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: if end device containing a wirelessusb lr module will be sold or used in europe, the enclosur e of the product must display a label with the following basic elements: if end device containing a wirelessusb lr module will be sold or used in canada, the enclosur e of the product must display a label with the following basic elements: as of march 2006, japan does not recognize the ?modular approval? certification. regul atory certification for japan (telec) must be acquired through typical approval proce- dures. these approvals are the so le responsibility of the oem. note: even with modular approval, t he 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 CYWM6935 contains fcc id: r8kugww2ushn33a contains fcc id: r8kugww2ushn33a contains fcc id: r8kugww2ushn33a CYWM6935 0122 CYWM6935 this product contains cypress wirelessusb module canadian cert no ic: 5125a-ugww2us this product contains cypress wirelessusb module canadian cert no ic: 5125a-ugww2us note: 1. this list is as of march 2006. please talk to your local sales person for the current list.
