产品概述

The 71M6543F-IGT/F is an energy meter IC in 100 pin LQFP package. This is 4th generation polyphase metering SoC 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 22bit delta-sigma ADC, seven analogue inputs, digital metrology temperature compensation, precision voltage reference and a 32bit CE supports a wide range of metering applications with very few external components. It supports 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 of flash memory which can be programmed with code and/or data during meter operation.
  • Supply voltage range is 3V to 3.6V
  • Operating temperature range from -40°C to 85°C
  • 0.1% typical accuracy over 2000:1 current range, exceeds IEC 62053/ANSI C12.20 standards
  • Four quadrant metering, phase sequencing, up to four pulse outputs with pulse count
  • 7 sensor inputs with neutral current measurement, differential mode selectable for current inputs
  • Selectable gain of 1 or 8 for one current input to support shunts & phase compensation (±7°)
  • 46Hz-64Hz line frequency range with the same calibration, 1µA in sleep mode
  • High speed Wh/VARh pulse outputs with programmable width, flash security & in system program update
  • Brownout, LCD & sleep battery backup modes & I2C/MICROWIRE EEPROM interface
  • Wake-up on pin events and wake-on-timer, hardware watchdog timer (WDT)
