WirelessUSB™ LP

The WirelessUSB LP (CYRF6936) is the second-generation 2.4 GHz RF technology from Cypress’s WirelessUSB family. It offers unmatched robustness and up to 100 m connection range with up to 1 Mbps data rate.

WirelessUSB LP supports a range of enhanced features including extended operating voltage range, best-in-class receive sensitivity and link budget, multiple data rate options, reduced crystal start up, synthesizer setting, and link turnaround times.  WirelessUSB LP consists of a 2.4 GHz 1 Mbps GFSK radio transceiver, DSSS baseband controller, packet data buffering, packet framer, Receiver Signal Strength Indication (RSSI), and SPI interface for data transfer and device configuration.

In addition, WirelessUSB LP radio has a Power Management Unit (PMU), which enables direct connection of the device to any battery voltage ranging from 1.8V to 3.6V.  The PMU conditions the battery voltage to provide the supply voltages required by the device and may also supply external devices
