71M6543H-IGTR/F

Overview

The 71M6543H-IGTR/F is a three-phase 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 5 MHz. The device features a 22-bit ADC resolution and supports multiple sensor inputs including current and voltage channels. It operates on a 3.3 V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in an LQFP-100 package and includes interfaces such as UART for communication.

Feature Summary

• Integrates a low-power real-time clock with digital temperature compensation
• Supports LCD driver functionality for display applications
• Utilizes Single Converter Technology with precision voltage reference
• Includes a 32-bit computation engine for high-accuracy metering

Applications

• Three-phase energy metering systems
• Polyphase smart grid infrastructure
• Industrial power monitoring equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to potential availability constraints. Confirm RoHS compliance status and specific suffix variations against official datasheets prior to ordering. Ensure supply chain stability as this part may be subject to limited distribution or special order requirements from the manufacturer.

Selection Notes

Select this SoC for designs requiring integrated MCU and metrology functions to reduce bill of materials cost. The 80515 core provides sufficient processing for complex tariff schemes. Verify interface compatibility with external sensors and displays. Consider thermal management requirements for the LQFP-100 package in enclosed enclosures.

Part Context

This component belongs to the 71M654x series of fourth-generation single-phase and polyphase metering SoCs. These devices are designed to replace discrete solutions by integrating analog front-end and digital processing. The series emphasizes BOM cost reduction while maintaining high accuracy standards required for utility-grade metering applications.

Replacement Considerations

Consult official documentation for qualified substitutes within the 71M654x family. Cross-reference pinouts and memory configurations when evaluating alternative models.
