General Description
Energy Meter ICs
The 71M6541DT/71M6541FT/71M6541GT/71M6542FT/
71M6542GT (71M654xT) are 4th-generation single-
phase 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 delta-
sigma 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 tam-
per, 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, demonstra-
tion code, and reference designs enable rapid develop-
ment and certification of meters that meet all ANSI and
IEC electricity metering standards worldwide.
The 71M654xT family operates over the industrial tempera-
ture range and comes in 64-pin (71M6541DT/FT/GT) and
100-pin (71M6542FT/GT) lead(Pb)-free LQFP packages.
