The 71M6511 and 71M6511H are highly integrated SoCs with an MPU core, RTC, flash, and LCD driver. Our Single Converter Technology® with a 22-bit, delta-sigma ADC; three analog inputs; digital temperature compensation; precision voltage reference; and 32-bit computation engine (CE) supports a wide range of single-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, I²C, a power-fail comparator, a 5V LCD charge pump, up to 12 DIO pins, and an in-system programmable flash. The device is offered in 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.
