Product Brief
TDK Semiconductor’s Power Meter ICs
Industrial Meters
Commercial Meters
Residential Meters
The TDK 71M6513 is a highly integrated SOC with an MCU core, RTC, FLASH and LCD driver.
TDK's Single Converter Technologywith 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, I2C, 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.
