GreenPeak GP691 Version 1.04 ZigBee Home Automation Communications Controller The GP691 ZigBee Home Automation Communications Controller provides a fully integrated solution for ultra low power wireless communications for smart home appliances. It is compliant with the IEEE Standard 802.15.4, providing robust spread spectrum data communication with a secure encrypted data flow. Its superior Wi-Fi interference rejection and antenna diversity offer additional robustness in a crowded wireless 2.4 GHz environment. The GP691 features a radio transceiver, integrated real-time Medium Access Control processor, integrated microcontroller, RAM and Flash memory, security engine, event scheduler, and an extensive set of peripherals. 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. Advanced power management features ensure that power consumption is minimized in active as well as in standby states, enabling maintenance free and very small form factor products. The GP691 is capable of running the full stack and application for ZigBee Pro applications, including ZHA and ZLL. Its 2 internal microcontroller can communicate with external devices via UART, SPI or I C interfaces.

No expensive shielding, chip antennas or voltage regulators are required to design a high performance Home Automation application. The integrated microcontroller and program memory allow for fully integrated, single chip applications and the integrated Real-Time MAC greatly reduces software complexity and improves stability. The GP691 has been optimized for reliable communication in harsh radio environments. The -96 dBm 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 combination of excellent receiver dynamic range and an auto tuned band-pass filter. Ultra Low Power Consumption The GP691’s advanced integrated energy management system allows it to operate from a standard lithium coin cell battery, like the CR2032, as well as from intermittent power supplies like photovoltaic (solar), electro-mechanical and piezoelectric, with a minimum of additional components. It includes ultra low power voltage level detectors and overvoltage protection circuitry, allowing safe operation and graceful shutdown. The battery lifetime monitor tracks the usage of the battery and provides an early exhaustion warning.
