Cypress CyFi Low-Power RF

The CyFi Low-Power RF solution is a highly reliable, easy-to-use 2.4-GHz answer to a wide range of wireless embedded control challenges. It enables designers to create wireless systems without making compromises to overcome the typical risks of unreliable performance, complex implementation, and high power consumption. By combining Cypress's PSoC programmable system-on-chip, a sophisticated yet lightweight network protocol stack, and a Direct Sequence Spread Spectrum (DSSS) transceiver, the CyFi solution achieves levels of reliability, simplicity, and power-efficiency unmatched by other embedded wireless technologies.
