71M6513/71M6513H

3-Phase Energy Meter IC

DATA SHEET

SEPTEMBER 2011

GENERAL DESCRIPTION

The 71M6513 is a highly integrated system-on-chip SoC with an MPU core,

real-time clock (RTC), flash, and LCD driver. Our Single Converter

Technology® with a 21-bit delta-sigma ADC, six analog inputs, digital tem-

perature compensation, precision voltage reference, and 32-bit computation

engine (CE) supports a wide range of poly-phase metering 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.

Maximum design flexibility is supported with multiple UARTs, I C, a power-

fail comparator, a 5V LCD charge pump, up to 22 DIO pins, and an in-

system programmable flash. The device is offered in high (0.1%) and

standard (0.5%) accuracy versions for multifunction residential/commercial

meter applications requiring multiple voltage/current inputs and complex

LCD or DIO configurations.

A complete array of ICE and development tools, programming libraries and

reference designs enable rapid development and certification of meters that

meet most demanding worldwide electricity metering standards.
