GP711 ® ZigBee Multi-Stack Communications Controller Product Brief Product Overview The GP711 System-on-Chip is an IEEE 802.15.4 communications controller for integration into a ZigBee node. It supports dual PAN operation with two (RF4CE, ZigBee Pro or ZigBee IP) protocol stacks in the host processor, and provides a high-speed serial interface (SPI) to the host processor. The GP711 is fully compliant with the IEEE 802.15.4 standard, providing robust spread spectrum data communication with a highly secure encrypted data flow. Its superior Wi-Fi interference rejection capability and antenna diversity offer additional robustness in a crowded wireless 2.4 GHz environment. In addition, the GP711 supports a Coexistence Interface to enable coexistence with other potentially interfering radios (Bluetooth, Wi-Fi) within the same device. The chip 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. The GP711 has an extreme low standby power enabling total system power consumption of less than 1 mW while allowing reception of messages from remote nodes.

The excellent receiver sensitivity allows extended coverage. Built-in antenna diversity with two antennas improves the reliable link budget by 9 dB resulting in approximately twice the reliable range compared to similar systems with only one antenna. In high density networks the packet-in-packet resynchronization further improves the communication reliability. The potential risks of interference by Wi-Fi and/or Bluetooth devices have been reduced by the excellent receiver interference rejection capability. The Coexistence Interface can be used to enable coexistence of the IEEE 802.15.4 radio of the GP711 with other potentially interfering radios (Wi-Fi, Bluetooth) within the same device.
