Energy Meter ICs  
DATA SHEET  
GENERAL DESCRIPTION  
FEATURES  
The 71M6541D/71M6541F/71M6541G/71M6542F/71M6542G are  
Teridian™ 4th-generation single-phase metering SoCs with a 5MHz  
8051-compatible MPU core, low-power RTC with digital temperature  
compensation, flash memory, and LCD driver. Our Single Converter  
Technology® with a 22-bit delta-sigma ADC, three or four analog  
inputs, digital temperature compensation, precision voltage reference,  
and a 32-bit computation engine (CE) supports a wide range of  
metering applications with very few external components.  
0.1% Accuracy Over 2000:1 Current Range  
Exceeds IEC 62053/ANSI C12.20 Standards  
Two Current Sensor Inputs with Selectable  
Differential Mode  
Selectable Gain of 1 or 8 for One Current Input to  
Support Shunts  
High-Speed Wh/VARh Pulse Outputs with  
Programmable Width  
The 71M6541/2 devices support optional interfaces to the Teridian  
71M6x01 series of isolated sensors, which offer BOM cost reduction,  
immunity to magnetic tamper, and enhanced reliability. Other  
features include an SPI interface, advanced power management,  
ultra-low-power operation in active and battery modes, 3/5KB shared  
RAM and 32/64/128KB of flash memory that can be programmed in  
the field with code and/or data during meter operation and the ability  
to drive up to six LCD segments per SEG driver pin. High  
processing and sampling rates combined with differential inputs offer  
a powerful metering platform for residential meters.  
32KB Flash, 3KB RAM (71M6541D)  
64KB Flash, 5KB RAM (71M6541F/42F)  
128KB Flash, 5KB RAM (71M6541G/42G)  
Up to Four Pulse Outputs with Pulse Count  
Four-Quadrant Metering  
Digital Temperature Compensation:

Metrology Compensation  
Accurate RTC for TOU Functions with  
Automatic Temperature Compensation for  
Crystal in All Power Modes  
A complete array of code development tools, demonstration code,  
and reference designs enable rapid development and certification of  
meters that meet all ANSI and IEC electricity metering standards  
worldwide.
