Overview
71M6541DT/71M6541FT/71M6541GT/ 71M6542FT/71M6542GT 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 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-low-power operation in active and battery modes, 3KB/5KB shared RAM, and 32KB/64KB/128KB 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 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 71M654xT family operates over the industrial temperature range and comes in 64-pin (71M6541DT/FT/GT) and 100-pin (71M6542FT/GT) lead(Pb)-free LQFP packages.
