71M6531F Datasheet Energy Meter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Simplifying System IntegrationTM GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 71M6531D/F and 71M6532D/F are highly integrated SOCs with an MPU core, RTC, FLASH and LCD driver.

The patented Single Converter Technology® with a 22-bit delta-sigma ADC, four analog inputs, digital temperature compensation, precision voltage reference, battery voltage monitor and 32-bit computation engine (CE) supports a wide range of residential metering 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.

Key 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 with CT, Rogowski or shunt, magnetic tamper input).
  • Line frequency count for RTC.
  • Digital temperature compensation.
  • Sag detection for phase A and B.
