GENERAL DESCRIPTION
BENEFITS AND FEATURES
Our Single Converter Technology® with a 22-bit delta-sigma ADC, three or four analog inputs, digital temperature compensation, precision voltage reference, and a 32-bit computation engine (CE) supports a wide range of metering applications with very few external components. Other features include an SPI interface, advanced power management, ultra-low-power operation in active and battery modes, 3/5KB shared RAM and 32/64/128KB of flash memory that can be programmed in the field with code and/or data during meter operation and the ability to drive up to six LCD segments per SEG driver pin. High processing and sampling rates combined with differential inputs offer a powerful metering platform for residential meters. 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. The 71M654x family operates over the industrial temperature range and comes in 64-pin (71M6541D/F/G) and 100-pin (71M6542F/G) lead(Pb)-free LQFP packages.
