Product Description

PCB Pluggable Connector ATM90E32AS-AU-R TQFP-48 Analog Front End - AFE


Product 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 three current 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 and fundamental/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 stability over variations in grid and ambient environment conditions.



• Poly-phase energy meters of class 0.2S, 0.5S and class 1 which are used in three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems. • Power monitoring instruments which need to measure voltage, current, mean power, etc.
