Electronica 2008 - Read our full show coverage from Munich
EnOcean has teamed up with wireless sensor manufacturer SensorDynamics to introduce its first energy harvesting wireless sensor IC.
The EO3000I Asic has been designed for EnOcean's Dolphin system architecture for in-building control systems.
It is designed to support the direct operation of the sensor interface and radio transceiver from various types of weak or strong energy converters - electrodynamic, solar or for differences in temperature, vibration and rotation.
"The Asic will power the breakthrough of highly sophisticated, energy-autonomous wireless systems in building automation applications," said Dr. Gerhard Schultes, Director, System Design, for SensorDynamics.
The chip incorporates an integrated sensor interface consisting of a pair of high precision analogue to digital converters (ADCs) and an arbitrary function generator, routable to various pins.
The on-chip RF transceiver covers the two ISM frequency bands 868 and 315MHz for worldwide license-free operation. The ASK transmission, bandwidth and data rates are in accordance with the EnOcean wireless standard.
The receiver uses fully digital IF signal processing to overcome process tolerances. The on-chip microcontroller has 32k on-board flash memory.
So for development the Dolphin API allows for programming of applications in the high-level C language.
The API is not only restricted to the protocol stack for EnOcean wireless - it also offers many other powerful functions, for the control of energy management for example, use of the digital or analog I/Os, access to flash memory and the continuously powered RAM0, and control of timer functions.
EnOcean is currently preparing its market roll out of the next generation of wireless sensor and transceiver modules based on the EO3000I chip, available in early 2009.
