Single chip combines powerline and wireless communications for the first time for smart energy management and electric vehicles

August 07, 2012 // By Nick Flaherty
Greenvity Communications has developed the first hybrid system-on-chip (SoC) family that integrates powerline communication (PLC) and wireless capabilities on a single chip.

The Greenvity Hybrii chip family supports both the HomePlug Green PHY PLC and ZigBee worldwide standards simultaneously to enable robust and intelligent connectivity for a variety of home and building energy management and electric vehicle applications. The first Hybrii family members include the Hybrii-XL chip for smart grid, smart energy management, industrial and consumer applications, and the Hybrii-PLC device for rugged, high temperature conditions.
Hybrii-XL makes smart grid products possible that for the first time integrate both PLC and ZigBee communication capabilities. The single-chip solution allows customers to reduce costs and power consumption by using one chip and one board, rather than the traditional approach requiring multiple chips and boards to support both standards.
When the Hybrii chip is deployed in an energy-efficient appliance, consumers are assured reliable, robust communication as well as ease of use. They don’t have to worry about which standard an appliance supports and can place the appliance anywhere in their house without worrying about wireless reception issues or multi-phase issues related to power lines. The Hybrii chip automatically chooses the best medium to transmit energy-related data—wirelessly or via existing power lines—and extends the range to cover an entire home or building. If wireless nodes are noisy due to interference then PLC will be enabled and vice versa, ensuring reliable communication.
“The Hybrii family of single-chip energy management solutions will help enable consumers and utilities to take advantage of the energy and cost savings promised by the smart grid and smart energy systems,” said Hung Nguyen, president and CEO of Greenvity Communications. “With our best-in-class hybrid chip offerings that support both HomePlug Green PHY and ZigBee standards, Greenvity aims to speed the adoption of smart energy products, as well as the growth of the electric vehicle market.”
The Hybrii-XL (GV7011) is a highly integrated single chip with HomePlug Green PHY PLC and ZigBee wireless functions integrated for low cost and lower power consumption. Both HomePlug Green
