Cypress Semiconductor CYRF6986
CYRF6986
Functional Description
The CYRF6986 WirelessUSB LPstar radio is a second generation member of the Cypress WirelessUSB Radio System-On-Chip (SoC)
family. The CYRF6986 IC adds a range of enhanced features, including reduced supply current in all operating modes, reduced crystal
start up, synthesizer settling, and link turnaround times.
