71M6543F/71M6543G
Energy Meter ICs
Shunt Current Sensors
GENERAL DESCRIPTION
The 71M6543F/71M6543G are 4th-generation polyphase metering
systems-on-chips (SoCs) with a 5MHz 8051-compatible MPU core,
low-power real-time clock (RTC) with digital temperature
compensation, flash memory, and LCD driver. 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.
