GP712 ® IEEE 802.15.4 Multi-Stack Multi-Channel Communications Controller Product Brief Product Overview The 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 protocol stacks in the host processor. These stacks can operate in different networks (PANs) and on different channels. The GP712is 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.

These PANs may be on the same or on different RF channels. Excellent Range and Reliability Electrical Characteristics Standby Mode Currents 1 Using internal RC oscillator 1.2 µA Using crystal oscillator 760 µA Operational Currents 1 Receive 14 mA Transmit (at 0 dBm) 18 mA Transmit (at 7 dBm) 30 mA Supply Voltage 2.1 to 3.6 V Interfaces SPI Slave serial host interface UART-based serial host interface Coexistence Interface with other radios External LNA/PA signals 2 Analog input lines ADC to monitor the analog input lines and the power supply level Crystal Frequency 32.000 MHz (±40 ppm) Radio Characteristics The GP712 has been optimized for reliable communication in harsh radio environments. The excellent receiver sensitivity and high transmit power allow extended coverage. Built-in antenna diversity with two antennas improves the reliable link budget by 8 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 an excellent receiver interference rejection capability and dynamic adaption of the frequency channel. Standards compliant The Coexistence Interface can be used to enable coexistence of the IEEE 802.15.4 radio of the GP712 with other potentially interfering radios (Wi-Fi, Bluetooth) within the same device. Data Rate Ultra-Low Power Consumption The GP712 is designed for ultra-low power network applications. It supports RF4CE duty cycling and can wake up the host when a specified message has been received, with RF4CE Network layer and Profile layer Deep Packet Inspection, to allow the host to stay asleep as much as possible.

The 8 dB in link budget translates into 70% more range, if using a two slope range model with the breakpoint at 10 m and g1 = 2, g2 = 3.5.
