2.0 Functional Description
The CYWUSB6932/CYWUSB6934 Integrated Circuits (ICs)
are highly integrated 2.4-GHz Direct Sequence Spread
Spectrum (DSSS) Radio System-on-Chip (SoC) ICs. From the
Serial Peripheral Interface (SPI) to the antenna, these ICs are
single-chip 2.4-GHz DSSS Gaussian Frequency Shift Keying
(GFSK) baseband modems that connect directly to a micro-
controller via simple serial interface.
The CYWUSB6932 transmit-only IC and the CYWUSB6934
transceiver IC are available in a small footprint 48-pin QFN
package.
