71M6521DH, 71M6521DE Energy Meter

71M6521DH Description

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

71M6521DH Features

* Up to 0.1% Wh Accuracy Over 2000:1 Current Range
* Exceeds IEC 62053/ANSI C 12.20 Standards
* Voltage Reference < 40 ppm/°C (< 20ppm/°C for 71M6521DH)
* Four Sensor Inputs
* VDD Referenced
* Low-Jitter Wh and VARh Pulse Test Outputs (10kHz max)

71M6521DH Applications

* with very few low-cost external components. A 32kHz crystal time base for the entire system and internal battery-backup support for RAM and RTC further reduce system cost. The ICs support 2-wire, 3-wire, and 4-wire singlephase and dual-phase residential metering along with tamper-detection mechanism
