71M6541D/F/G and 71M6542F/G

Energy Meter ICs

GENERAL DESCRIPTION

FEATURES

The 71M6541D/71M6541F/71M6541G/71M6542F/71M6542G 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.

• 0.1% Typical 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 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

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.

Accurate RTC for TOU Functions with

Automatic Temperature Compensation for
