71M6513H Datasheet | Silergy

71M6513/71M6513H 3-Phase Energy Meter IC GENERAL DESCRIPTION The 71M6513 is a highly integrated system-on-chip SoC with an MPU core, real-time clock (RTC), flash, and LCD driver. Our Single Converter Technology® with a 21-bit delta-sigma ADC, six analog inputs, digital temperature pensation, precision voltage reference, and 32-bit putation engine (CE) supports a wide range of poly-phase metering applications with very few low-cost external ponents. 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 powerfail parator, a 5V LCD charge...
