Product Brief

71M6513

71M6513H

TDK Semiconductor’s Power Meter ICs

The TDK 71M6513 is a highly integrated SOC with an MCU core, RTC, FLASH and LCD driver.

TDK's Single Converter Technology

™

with a 21bit 2nd order delta-sigma ADC, 6 analog inputs,

digital temperature compensation, precision voltage reference and 32 bit computation engine

supports a wide range of polyphase metering applications with very few low cost external com-

ponents. A 32kHz crystal timebase 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, power fail comparator,

5V LCD charge pump, up to 22 DIO pins and in-system programmable FLASH which can be

updated with data or application code in operation. Easy conversion to ROM offers unprec-

edented cost structure for high volume applications. The device is offered in high (0.1%) and

low (0.5%) accuracy versions for multifunction residential/commercial meter applications

requiring multiple voltage/current inputs, larger LCD or DIO features.

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.
