1.0  
Features  
2.0  
Functional Description  
• The CYWM6935 LR2.4-GHz DSSS Radio SoC Module  
includes radio (CYWUSB6935) , antenna, and all exter-  
nal components  
The CYWM6935 WirelessUSB LRRadio Module offers a  
complete radio module solution for integration into existing or  
new 2.4-GHz products.  
• Complete Radio Module with Dual PCB Trace Antennas  
The CYWM6935 is tested for functional operation and is  
FCC/ETSI(EU)/Industry pre-certified. The module is supplied  
with dual integrated PCB trace antennas.  
• Operates in the unlicensed Industrial, Scientific, and  
Medical (ISM) band (2.4 GHz–2.483 GHz)  
The CYWM6935 is available in a small PCBA design and can  
be mounted horizontally to the device PCB via a 12-pin  
header. The pin-out of the header is shown in Figure 4-1.  
• –95-dBm receive sensitivity  
• Up to 0-dBm output power  
• Range of up to 50 meters or more  
• Data throughput of up to 62.5 kbits/sec  
• SPI microcontroller interface (up to 2 MHz data rate)  
• Operating voltage from 2.7V to 3.6V

• Small PCBA Design: 0.95” (23.75 mm) by 0.95” (23.75  
mm) by 0.212” (5.3 mm) (L x W x H)  
• FCC Modular Approval Grant to meet FCC Part 15, EN  
300 328-1, EN 301 489-1, and Industry Canada RSS-210  
standards  
• Building/Home Automation  
— Climate Control  
— Lighting Control  
• An FCC Module Approval (MA) Grant provides  
customers significant cost savings, by allowing  
customers to adopt the CYWM6935 FCC ID into their  
own products

Applications Support  
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.  
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.
