GP501

    IEEE 802.15.4 Communications Controller

    Key Features

    • IEEE 802.15.4 compliant PHY and Real-Time MAC
    • Excellent range by antenna diversity: 9 dB more reliable link budget compared to single antenna
    • Additional robustness by packet-in-packet resynchronization
    • 30 dB better robustness to Wi-Fi Interference
    • External LNA/PA signals for extended range
    • Hardware accelerated AES and CCM encryption with 128, 192 and 256-bit keys
    • 1.5 Kbyte RAM for data buffering
    • Advanced Energy Management, supporting intermitted energy sources and coin cell battery operation
    • External Controller SPI Slave interface
    • Stand-alone RF4CE DutyCycling support and RF4CE packet filtering when the host is asleep
    • Coexistence Interface with 3rd party radios

    The Qorvo GP501 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 GP501 interference robustness and antenna diversity offer superior performance in a crowded wireless 2.4 GHz environment. In addition, the GP501 presents a Coexistence Interface to enable coexistence with other potentially interfering radios (Bluetooth, Wi-Fi) within the same host device.

    The GP501 features a radio transceiver, integrated real-time Medium Access Control processor, security engine, event scheduler and advanced power management features. A high-speed SPI interface is provided for communication with the external controller. The integrated RF filtering simplifies the RF design complexity enabling very low cost single layer applications using simple PCB antennas requiring no shielding and a minimum number of external components. The embedded security engine automatically encrypts, decrypts and authenticates messages with locally stored keys, so minimizing the overhead for the controller. Advanced power management features ensure that power consumption is minimized in both active and standby states.

    The combination of a GP501 with a microcontroller forms an IEEE 802.15.4 node, examples of which include a Zigbee coordinator, router or end device, or an rf4ce Target or Controller device.
