Our Single Converter Technology® with a 22-bit delta-sigma ADC, seven analog inputs, digital metrology temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components. The 71M6543F/71M6543G support optional interfaces to the 71M6xx3 series of isolated sensors that offer BOM cost reduction, immunity to magnetic tamper, and enhanced reliability. The ICs feature ultra-low-power operation in active and battery modes, 5KB shared RAM, and 64KB (71M6543F) or 128KB (71M6543G) of flash memory, which can be programmed with code and/or data during meter operation. A complete array of code development tools, demonstration code, and reference designs enable rapid development and certification of meters that meet all ANSI and IEC electricity metering standards worldwide.
