General description
The M90E32AS is a poly-phase high performance wide-dynamic range metering IC. The M90E32AS incorporates 6 independent 2nd order sigma-delta ADCs, which could be employed in three voltage channels (phase A, B and C) and threecurrent channels (phase A, B, C) in a typical three-phase four-wire system.The M90E32AS has an embedded DSP which executes calculation of active energy, reactive energy, apparent energy, fundamental and harmonic active energy over ADC signal and on-chip reference voltage. The DSP also calculates measurement parameters such as voltage and current RMS value as well as mean active/reactive/apparent power.A four-wire SPI interface is provided between the M90E32AS and the external microcontroller.The M90E32AS is suitable for poly-phase multi-function meters which could measure active/reactive/apparent energy andfundamental/harmonic energy either through four independent energy pulse outputs CF1/CF2/CF3/CF4 or through the corresponding registers.The ADC and auto-temperature compensation technology for reference voltage ensure the M90E32AS's long-term stabilityover variations in grid and ambient environment conditions.
