71M6543GT-IGTR/F

Overview

The 71M6543GT-IGTR/F is a third-generation polyphase metering System on Chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates an 80515 MPU core with 128 kB Flash and 5 kB SRAM, operating at a maximum clock frequency of 10 MHz. The device features a 22-bit ADC resolution and supports up to four current sensors and three voltage sensors. It includes two UART interfaces, 51 GPIOs, and an LCD driver capable of supporting 336 segments. Operating within a temperature range of -40°C to +85°C, it utilizes a 3.3 V supply and is housed in an LQFP-100 package.

Feature Summary

• Integrates a high-performance 80515 MPU core with substantial onboard memory for complex metering algorithms.
• Supports multiple sensor input configurations including CT, shunt, and Rogowski coils for versatile installation.
• Features a built-in real-time clock and extensive LCD driver capabilities for direct display interfacing.

Applications

• Polyphase energy metering systems
• Smart grid infrastructure monitoring
• Industrial power management units

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance requirements against specific regional regulations before procurement. Ensure compatibility with existing development kits such as the 71M6533-DB for validation purposes. Review current supply constraints and lead times directly with the supplier prior to finalizing orders.

Selection Notes

Select this component for applications requiring integrated polyphase measurement capabilities without external isolation transformers. Consider the 80515 core architecture for software compatibility with existing Teridian codebases. Evaluate the 22-bit ADC performance against required accuracy standards. Compare pin counts and memory sizes against alternative models like the 71M6542G if fewer I/O resources are sufficient.
