3-Phase Energy Meter ICs

Part Number	Status
71M6513	Active: In Production. See Ordering Information for details.
71M6513H	Active: In Production. See Ordering Information for details.

The 71M6513 and 71M6513H are highly integrated SoCs with an MPU core, RTC, flash, and LCD driver. Our Single Converter Technology® with a 21-bit, delta-sigma ADC; six analog inputs; digital temperature compensation; precision voltage reference; and 32-bit computation engine (CE) supports a wide range of polyphase 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, I²C, a power-fail comparator, a 5V LCD charge pump, up to 22 DIO pins, and an in- system programmable flash. The device is a standard (0.5%) accuracy version 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.
