CYRF6936-40LTXC Datasheet PDF - Cypress Semiconductor

●The CYRF6936-40LTXC is a WirelessUSB™ LP 2.4GHz Radio SoC IC for use with remote controls. The CYRF6936 WirelessUSB™ LP radio is a second generation member of the Cypress wireless USB 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.
