描述 Description

The Qorvo GP502 ZigBee-ready IEEE 802.15.4 communications controller is a fully integrated transceiver solution for ultra-low power wireless communications. It is compliant with the IEEE Standard 802.15.4, providing robust spread spectrum data communication with a secure encrypted data flow.The GP502 interference robustness and antenna diversity offer superior performance in a crowded wireless 2.4 GHz environment. In addition, the GP502 presents a Coexistence Interface to enable coexistence with other potentially interfering radios (Bluetooth, Wi-Fi) within the same host device.The GP502 provides a high-speed serial interface (SPI or UART) to the host processor.  It supports stand-alone RF4CE DutyCycling and packet filtering through Deep Packet Inspection when the host is asleep and has an extremely low standby power consumption enabling total system power consumption of less than 1 mW while allowing reception of remote control commands.The GP502 is optimized for low cost while providing superior performance. Its radio characteristics reduce the product’s RF design complexity enabling low cost single layer applications using simple PCB antennas requiring no shielding and a minimum number of external components.
