71M6532F-IGTR/F

Overview

The 71M6532F-IGTR/F is a single-phase and two-phase energy 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 current sensors including CT, shunt, and Rogowski coils, featuring an accuracy of ±0.1% at a 2000:1 ratio. It includes an RTC, LCD driver supporting up to 268 segments, and 43 GPIOs. Communication interfaces include two UARTs. The component operates within a temperature range of -40°C to +85°C and is housed in a 100-LQFP package.

Feature Summary

• Integrates high-precision metering capabilities with an embedded 80515 microprocessor core for system control.
• Supports multiple sensor input types including current transformers, shunts, and Rogowski coils.
• Includes dedicated hardware for real-time clock functions and LCD display driving.

Applications

• Single-phase energy metering systems
• Two-phase energy metering applications

Procurement Notes

Verify the specific suffix 'IGTR/F' against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm availability as distribution channels may list this part as obsolete or limited supply. Ensure the selected variant matches the required firmware and hardware configuration for your design.

Selection Notes

Select this SoC for designs requiring integrated metering and processing in a compact form factor. Consider the 256 KB Flash capacity for complex metering algorithms. Verify that the 100-LQFP package fits the PCB layout constraints. Check if the built-in LCD driver meets segment requirements before selecting external drivers.

Part Context

This component belongs to the 71M series of precision energy metering SoCs from Analog Devices/Maxim Integrated. These devices are designed to replace discrete solutions by combining analog front-end signal conditioning with digital processing cores. The 71M6532 variant specifically targets cost-sensitive yet accurate metering applications in residential and commercial sectors.

Replacement Considerations

Check for direct replacements like the 71M6532D or other variants within the 71M65xx family. Verify pin compatibility and software migration paths when considering alternative packages or updated revisions from the manufacturer.
