At CES 2015, GreenPeak Technologies announced a new GP691 ZigBee communication controller chip and GPM6000 integrated ZigBee modules for Internet of Things applications and smart home devices.
The GP691 ZigBee communications controller provides IEEE Standard 802.15.4-compliant robust spread spectrum data communication in the worldwide 2.4-GHz band. It can run the full stack and application for ZigBee applications, including ZHA and ZLL profiles. In addition to a radio transceiver, the GP691 comprises a real-time Medium Access Control (MAC) processor, microcontroller, security engine, 16-KB RAM, and 248-KB flash memory. The GP691 is over the air upgradable and includes support for new 802.15.4-based standards upon availability, such as Thread.
ZigBee 3.0 supports a wide range of applications (e.g., home, industrial automation, and smart energy). IEEE 802.15.4-compliant, it can cover a complete home with multiple floors. Plus, it can manage dead spots and Wi-Fi interference via mesh networking. ZigBee 3.0 also supports large networks comprising thousands of devices, which also makes it suitable for industrial applications and building automation. ZigBee 3.0 also includes Green Power, part of the ZHA and ZLL profiles, which supports energy harvesting and battery-free applications. Without requiring batteries, these self-supporting devices typically generate (harvest) just enough power to transmit a brief command to the network via ZigBee.
With its partner Universal Scientific Industrial (Shanghai) Co, Ltd (USI), GreenPeak developed “an integrated module for the GP691 that reduces product design company’s time to market without having to solve RF product integration challenges or to worry about international wireless certification.”
The 25 x 17 x 2.5 mm pre-integrated, pre-certified module adds a power stage/LNA providing up to 20-dBm output power, special transmit and receive circuitry, and an integrated antenna plus a connector for a second external antenna enabling antenna diversity configurations, which all together, allow for greater range and robustness, providing coverage throughout an entire home. This module will be offered as the first in the GPM6000 module series optimized for smart home solutions.
