71M6543F-IGTR/F

Overview

The 71M6543F-IGTR/F is a third-phase energy metering System-on-Chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates an 80515 processor core with 128 kB of Flash program memory and 5 kB of SRAM. The device features a 22-bit ADC resolution, supports up to 51 GPIOs, and includes two UART interfaces. Operating at a maximum clock frequency of 10 MHz on a 3.3 V supply, it is housed in an LQFP-100 package suitable for surface mount applications.

Feature Summary

• Integrates a high-performance 80515 MPU core with substantial onboard memory for complex metering logic
• Utilizes precision analog front-end technology to support multiple current sensor types including CT, shunt, and Rogowski coils
• Provides extensive digital connectivity through dual UART interfaces and a large number of general-purpose I/O pins

Applications

• Three-phase residential and commercial electricity metering systems
• Smart grid infrastructure monitoring nodes
• Industrial power quality analysis equipment

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited supply status. Confirm RoHS compliance requirements against specific regional regulations as indicated in official documentation. Ensure compatibility with existing PCB footprints and thermal management solutions before finalizing procurement orders.

Selection Notes

Select this model for applications requiring three-phase measurement capabilities combined with robust processing power. Consider the 128 kB Flash capacity for complex firmware implementations. Evaluate the LQFP-100 package constraints against board space limitations. Compare against single-phase variants if only one phase measurement is required to optimize cost.
