Functional Description
The CYRF6936 WirelessUSB™ LP radio is a second gener-
ation member of Cypress’s WirelessUSB Radio
System-On-Chip (SoC) family. The CYRF6936 is interop-
erable with the first generation CYWUSB69xx devices. The
CYRF6936 IC adds a range of enhanced features, including
increased operating voltage range, reduced supply current in
all operating modes, higher data rate options, and reduced
crystal start up, synthesizer settling and link turnaround times.
