71M6541DT/71M6541FT/71M6541GT/ 71M6542FT/71M6542GT EVALUATION KIT AVAILABLE Energy Meter ICs General Description The 71M6541DT/71M6541FT/71M6541GT/71M6542FT/ 71M6542GT (71M654xT) are 4th-generation singlephase metering systems-on-chips (SoCs) with a 5MHz, 8051-compatible MPU core, low-power RTC with digital temperature compensation, flash memory, and LCD driver. Our Single Converter Technology® with a 22-bit deltasigma ADC, three or four analog inputs, digital temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) support a wide range of metering applications with very few external components. The 71M654xT devices support optional interfaces to the Maxim Integrated 71M6x01 series of isolated sensors offering BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. Other features include an SPI interface, advanced power management, ultra-lowpower operation in active and battery modes, 3KB/5KB shared RAM, and 32KB/64KB/128KB flash...
