71M6531D/F, 71M6532D/F Energy Meter IC GENERAL DESCRIPTION The 71M6531D/F and 71M6532D/F are highly integrated SOCs with an MPU core, RTC, FLASH and LCD driver. The patented Single Converter Technology® with a 22-bit delta-sigma ADC, four analog inputs, digital temperature compensation, precision voltage reference, battery voltage monitor and 32-bit computation engine (CE) supports a wide range of residential metering applications with very few lowcost external components. A 32-kHz crystal time base for the entire system and internal battery backup support for RAM and RTC further reduce system cost. The IC supports 2-wire, and 3-wire single-phase and dual-phase residential metering along with tamper-detection mechanisms.
