71M6521DE Datasheet Energy Meter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-5370; Rev 3; 7/12 71M6521DE/DH/FE Energy Meter ICs DATA SHEET.

General Description

The Teridian™ 71M6521DE/DH/FE energy meter ICs are highly integrated systems-on-a-chip (SoCs) with an MPU core, RTC, flash, and LCD driver.

The Single Converter Technology® with a 22-bit delta-sigma ADC, four analog inputs, digital temperature pensation, precision voltage reference, battery voltage monitor, and 32-bit putation engine (CE) supports a wide range of residential metering applications with very few low-cost external ponents.

A 32kHz crystal time base for the entire system and internal battery-backup support for RAM and RTC further reduce system cost.
