71M6541D/F/G and 71M6542F/G  
Energy Meter ICs  
GENERAL DESCRIPTION  
BENEFITS AND FEATURES  
The 71M6541D/71M6541F/71M6541G/71M6542F/71M6542G (71M654x) are  
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.  
•
SoC Integration and Unique Isolation Technique  
Reduces BOM Cost Without Sacrificing

•
Exceeds IEC 62053/ANSI C12.20 Standards  
Four-Quadrant Metering  
46-64Hz Line Frequency Range with the  
Same Calibration  
Phase Compensation ( 10°)  
The 71M6541/2 devices support optional interfaces to the 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.
