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.

GP691 ZigBee Home Automation Communications Controller
Low Cost
Excellent Range and Reliability
The GP691 is designed to operate on very low cost, single layer,
paper phenol like PCB material using only low cost components
and printed circuit antennas. 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.

1) At 3.0V and 25°C, unless specified otherwise.
2) For typical indoor usage in an environment with 50 ns delay spread
and 2 MHz signal bandwidth using the Rayleigh fading model:
antenna diversity with 2 antennas results in a 9 dB improved link
budget at a 1% outage probability compared to no antenna diversity.
The 9 dB in link budget translates into 80% more range, if using a two
slope range model with the breakpoint at 10m and g1 = 2, g2 = 3.5.
