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 t

he 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.
