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 components. 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 unprecedented 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.
