CYWUSB6941
WirelessUSB™ EX Radio
1.0 Features
The Cypress CYWUSB6941 WirelessUSB™ EX radio trans-
ceiver is designed to work with the Cypress CYWUSB6942
WirelessUSB EX baseband controller to provide a complete
WirelessUSB EX solution. The CYWUSB6941 contains a
2.4-GHz radio transceiver, a GFSK modem, and a radio
control interface that communicates with the CYWUSB6942.
www.DataSheet•4UT.ycopmically requires only eight external components for
ease of implementation and manufacturing
• -6-dBm (typical) transmit power for a transmission
range of up to 10 meters
• -82-dBm (typical) receive sensitivity
• Provides low-power operating modes to conserve
battery life
• 2.7V to 3.6V operation
• 7 x 5 x 1.2 mm 42-pin FBGA package
2.0 Applications
The CYWUSB6941 is targeted for the following Human Input
Device (HID) applications:
• Mice
• Keyboards
• Joysticks/Gamepads.
