STMicroelectronics EVALSTPM3x Evaluation Boards

STMicroelectronics EVALSTPM3x Evaluation Boards are designed to help evaluate STMicroelectronics STPM3x Single Phase Metering ICs. The STPM3x is an ASSP family designed for high accuracy measurement of power and energy in power line systems using the Rogowski coil, current transformer or shunt current sensors. These devices have up to two voltages and two current channels, for energy measurement in dual-phase and single-phase (with or without neutral current monitoring) electricity metering systems. The STPM3x devices provide instantaneous voltage and current waveforms and calculate voltage and current RMS values, active, reactive and apparent powers and energies for each channel. Moreover, they embed a full set of calibration and compensation parameters which allow the meter to fit tight accuracy standards (EN 50470-x, IEC 62053-2x, ANSI12.2x for AC watt meters). All calculated data, as well as configuration parameters, are stored in internal 32-bit registers accessible through SPI or UART peripheral.
