The 71M6543G-IGT/F is a 4th-generation polyphase metering system-on-chip (SoC) from Analog Devices / Maxim Integrated, designed for advanced energy metering applications. It integrates an 8051-compatible MPU core, a low-power real-time clock with digital temperature compensation, flash memory, and an LCD driver.
This device boasts a 22-bit delta-sigma ADC, seven analog inputs, and a 32-bit computation engine, supporting a wide range of metering needs with minimal external components. Key features include 0.1% typical accuracy over a 2000:1 current range, exceeding IEC 62053/ANSI C12.20 standards. It offers 128KB of flash memory and 5KB of RAM, suitable for code and data storage during meter operation.
The 71M6543G-IGT/F supports four-quadrant metering and phase sequencing, with digital temperature compensation for metrology and an accurate RTC for Time-of-Use (TOU) functions. It operates within a 3 V to 3.6 V supply voltage range and has an operating temperature range of -40°C to 85°C.
Packaged in a 100-LQFP surface-mount form factor, this IC is designed for efficient integration into 3-phase energy meters. Its ultra-low-power operation in active and battery modes, along with wake-up capabilities, makes it suitable for diverse metering environments.
