CyFi™ Low-Power RF

CyFi (CYRF7936) is a 2.4 GHz ISM radio transceiver, capable of supporting data rates upto 1 Mbps. It features a 1-Mbps GFSK radio front-end, packet data buffering, packet framer, DSSS baseband controller, and RSSI.


CyFi allows implementation of mixed-rate systems in which different devices use different data rates. It also allows the implementation of dynamic data rate systems that use high data rates at shorter distances.


The CYRF7936 IC has a power management unit (PMU), which allows direct connection of the device to any battery voltage in the range 1.8 V to 3.6 V.


CyFi features the CyFi Star Network Protocol Stack that maximizes reliability and power-efficiency in a wireless networkby having up to 250 wireless nodes.
