IEEE 802.15.4 Multi-Stack Multi-Channel Communications Controller

    Key Features

    • IEEE 802.15.4 compliant PHY and Real-Time MAC
    • Excellent range by antenna diversity: 8 dB more reliable link budget compared to single antenna
    • Additional robustness by packet-in-packet resynchronization
    • External PA signals for extended range
    • Hardware accelerated AES and CCM encryption with 128, 192 and 256-bit keys
    • 8 Kbyte RAM for data buffering
    • Extremely low standby power consumption
    • External Controller SPI or UART Slave interface
    • Stand-alone RF4CE DutyCycling support and rf4ce packet filtering when the host is asleep
    • Multi-Stack Multi-Channel support, operating in up to 3 PANs on different channels
    • Coexistence Interface with 3rd party radios

    The Qorvo GP712 System-on-Chip is an IEEE 802.15.4 multi-stack multi-channel communications controller for integration into a Zigbee® node. It is compliant with the IEEE Standard 802.15.4, providing robust spread spectrum data communication with a secure encrypted data flow, and supports multiple Zigbee® 3.0 (including rf4ce, Zigbee® Pro and Green Power) and Thread (OpenThread  protocol stacks in the host processor. These stacks can operate in different networks (PANs) and on different channels. The GP712 is able to listen simultaneously on three different channels with antenna diversity.

    The GP712 interference robustness and antenna diversity offer superior performance in a crowded wireless 2.4 GHz environment. In addition, the GP712 presents a Coexistence Interface to enable coexistence with other potentially interfering radios (Bluetooth®, Wi-Fi) within the same host device.

    The GP712 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 GP712 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.
