71M6534H-IGT/F

Overview

The 71M6534H-IGT/F is a three-phase metering System on Chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates an 80515 user MPU core with 256 kB of Flash memory and 4 kB of SRAM. The device supports four differential current inputs and three voltage inputs, enabling high-precision energy measurement with ±0.1% accuracy at a 2000:1 range. It features a Real-Time Clock (RTC), a 300-segment LCD driver, and 52 GPIOs. Communication is facilitated via two UART interfaces. The component operates within a temperature range of -40°C to +85°C and is housed in a LQFP-120 package.

Feature Summary

• Integrates a dedicated 80515 microprocessor core for embedded control applications
• Supports multiple current sensor types including CT, shunt, and Rogowski coils
• Includes built-in real-time clock functionality for time-stamped data logging
• Features integrated display drivers for direct LCD panel interfacing

Applications

• Three-phase smart electricity metering systems
• Industrial power monitoring equipment
• Multi-tariff energy meters requiring high precision
• Grid infrastructure sensing nodes

Procurement Notes

Verify the specific suffix 'IGT/F' against official Analog Devices documentation to confirm tape-and-reel packaging status and lead-free compliance. Confirm availability through authorized distributors as supply may be limited. Ensure the selected variant matches the required LQFP-120 footprint and pinout configuration for your PCB design.

Selection Notes

Select this SoC when designing multi-phase metering solutions requiring integrated processing and analog front-end capabilities. The inclusion of an RTC and extensive GPIO makes it suitable for standalone units without external controllers. Consider the 256 kB Flash capacity for complex firmware requirements and utility protocols.

Part Context

This component belongs to the 71M65xx series of metering SoCs from Analog Devices/Maxim Integrated. It is part of a family that includes variants like the 71M6533 and 71M6534H, designed specifically for high-accuracy energy measurement. The series targets utility-grade applications demanding robust integration of processing, memory, and analog signal conditioning.

Replacement Considerations

Check for 71M6534H or 71M6533H variants if different packaging or memory configurations are acceptable. Verify compatibility with existing firmware due to potential differences in peripheral initialization between closely related SoC models.
