71M6513H-IGTR/F

The 71M6513H-IGTR/F is a sophisticated 3-Phase Energy Meter IC developed by Analog Devices, part of their Single Converter Technology® line. This system-on-chip (SoC) integrates an MPU core, real-time clock (RTC), flash memory, and an LCD driver, designed for poly-phase metering applications.

Key electrical specifications include a high accuracy of 0.1% over a 2,000:1 current range, exceeding standards like IEC 62053 and ANSI C12.20. It operates within a voltage range of 3V to 3.6V and supports a line frequency range of 40-70Hz with consistent calibration. The device includes a precision voltage reference with low temperature drift (< 10ppm/°C for the 71M6513H variant) and features digital temperature compensation.

Designed for flexibility, the 71M6513H offers features such as four-quadrant metering, phase sequencing, and battery backup for RAM and RTC. It includes up to 22 general-purpose I/O pins, two UARTs, and an integrated LCD driver capable of supporting up to 168 pixels. The IC is housed in a 100-pin LQFP package, suitable for surface mounting.

This energy meter IC is well-suited for multi-function residential and commercial meter applications requiring precise measurement and complex configuration options. Its integrated features reduce the need for external components, simplifying design and lowering system costs.
