Functional Description
The CYRF6936 WirelessUSB™ LP radio is a second generation member of the Cypress WirelessUSB Radio System-On-Chip
(SoC) family. The CYRF6936 is interoperable 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, reduced crystal start up, synthesizer settling, and link turnaround times.
