Reduces BOM Cost Without Sacrificing Performance

• 0.1% Typical Accuracy Over 2000:1 Current

Range

The 71M6543FT/71M6543HT/71M6543GT/71M6543GHT

(71M654xT) are 4th-generation three-phase metering

systems-on-chips (SoCs) with a 5MHz, 8051-compat-

ible MPU core, low-power RTC with digital temperature

compensation, flash memory, and LCD driver. Our Single

• Exceeds IEC 62053/ANSI C12.20 Standards

• Four-Quadrant Metering

•ꢀ 46-64HzꢀLineꢀFrequencyꢀRangeꢀwithꢀtheꢀSame

Calibration

• Phase Compensation (±10º)

• Independent 32-Bit Compute Engine

• 64KB Flash, 5KB RAM (71M6543FT/71M6543HT)

• 128KB Flash, 5KB RAM (71M6543GT/71M6543GHT)

• Built-In Flash Security

• SPI Interface with Flash Program Capability

• Up to Four Pulse Outputs with Pulse Count

• 8-Bit MPU (80515), Up to 5 MIPS

• Full-Speed MPU Clock in Brownout Mode

• LCD Driver Allows Up to 6 Commons/Up to

56 Pins

Converter Technology with a 22-bit delta-sigma ADC,

seven analog inputs, digital temperature compensation,

precision voltage reference, and a 32-bit computation

engine (CE) support a wide range of metering applications

with very few external components.

The 71M654xT devices support optional interfaces to the

Maxim Integrated 71M6x03 series of isolated sensors

offering BOM cost reduction, immunity to magnetic tam-

per, and enhanced reliability. Other features include an

SPI interface, advanced power management, ultra-low-

power operation in active and battery modes, 5KB shared

RAM, and 64KB/128KB flash memory that can be pro-

grammed 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 platform

for residential meters.

• Up to 51 Multifunction DIO Pins

• Hardware Watchdog Timer (WDT)

• Two UARTs for IR and AMR

• IR LED Driver with Modulation

• I C/MICROWIRE® EEPROM Interface

●ꢀ InnovativeꢀIsolationꢀTechnologyꢀ(Requiresꢀ

Companion 71M6xxx Sensor, also from Maxim

Integrated) Eliminates Current Transformers

• Four Current Sensor Inputs with Selectable

Differential Mode

A complete array of code development tools, demonstra-

tion code, and reference designs enable rapid develop-

ment and certification of meters that meet all ANSI and

IEC electricity metering standards worldwide.

• Selectable Gain of 1 or 8 for One Current Input to

Support Neutral Current Shunt

• High-Speed Wh/VARh Pulse Outputs with

Programmable Width

The 71M654xT family operates over the industrial tem-

perature range and comes in a 100-pin lead(Pb)-free

LQFP package.
