data brief for further information contact your local stmicroelectronics sales office. november 2008 rev 1 1/8 8 STEVAL-IPE008V1 energy meter (3-phase) demonstration board based on the stpm01 and str715fr0 features 3-phase meters multi-chip topology, in which each phase is monitored using a single-phase device common clock network power supply in fly-back topology using a viper12adip-e description the STEVAL-IPE008V1 demonstration board shows how to design a 3-phase meter using stpm01 as measuring device and a viper12adip-e as smps (switch mode power supply). the stpm01 is a metering assp implemented in an advanced 0.35 m bcd6 technology. it is designed for the effective measurement of active, reactive, apparent energies, v rms , i rms , instantaneous voltage and current, and frequency in power line systems that use the current transformer, rogowski coil and/or shunt principle. this device can be used as a standalone on-board metering device in single- phase energy meter applications or as a peripheral in a microprocessor based single- or 3- phase meter. in a standalone configuration stpm01 outputs a pulse train signal having a frequency proportional to the active power used, while in peripheral mode stpm01 is used in a microprocessor based application. in this case, measured data are read at a fixed interval from the device internal registers by means of spi interface processed by a microcontroller. am0 3 20 3 v1 s teval-ipe00 8 v1 www.st.com
