General Description

The 71M6543FT/71M6543HT/71M6543GT/71M6543GHT (71M654xT) are 4th-generation three-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, seven 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 71M6x03 series of isolated sensors offering BOM cost reduction, immunity to magnetic tamper, and enhanced reliability.

Overview

71M6543FT/71M6543HT/ 71M6543GT/71M6543GHT EVALUATION KIT AVAILABLE Energy Meter ICs.

Key Features

  • include an SPI interface, advanced power management, ultra-lowpower operation in active and battery modes, 5KB shared RAM, and 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 des.
