71M6531D/F, 71M6532D/F Energy Meter IC GENERAL DESCRIPTION The 71M6531D/F and 71M6532D/F are highly integrated SOCs with an MPU core, RTC, FLASH and

Features

* Wh accuracy < 0.1% over 2000:1 current range
* Exceeds IEC62053/ANSI C12.20 standards
* Four sensor inputs
* Low-jitter Wh and VARh plus two additional pulse test outputs (4 total, 10 kHz maximum) with pulse count
* Four-quadrant metering
* Tamper detection (Neutral current

Applications

* with very few lowcost external components. A 32-kHz crystal time base for the entire system and internal battery backup support for RAM and RTC further reduce system cost. The IC supports 2-wire, and 3-wire single-phase and dual-phase residential metering along with tamper-detection mechanisms. The
