71M6533G-IGTR/F

Overview

The 71M6533G-IGTR/F is a single-phase energy metering System on Chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates an 80515 core with a maximum clock frequency of 10 MHz, featuring 128 kB of Flash program memory and 4 kB of data RAM. The device utilizes Single Converter Technology with a 22-bit ADC resolution for precision measurement. It operates at a supply voltage of 3.3 V within a temperature range of -40°C to +85°C. The component is housed in a 100-LQFP package and supports I2C and UART interfaces.

Feature Summary

• Integrates an 80515-compatible microprocessor core with flash memory and low-power real-time clock
• Utilizes Single Converter Technology with a delta-sigma ADC for high-precision analog-to-digital conversion
• Includes digital temperature compensation and a precision voltage reference for stable operation
• Supports multiple sensor inputs including current transformers, shunts, and Rogowski coils

Applications

• Single-phase residential electricity metering
• Smart grid endpoint devices
• Energy monitoring systems requiring high accuracy

Procurement Notes

Verify availability through Analog Devices official channels as distribution status may vary. Confirm that the specific suffix matches required packaging and lead-free specifications. Ensure compatibility with existing design infrastructure before procurement. Request updated datasheets directly from the manufacturer to confirm current revision status and any potential obsolescence notices associated with this part number.

Selection Notes

Select this component for applications requiring integrated metering and processing capabilities in a compact form factor. The 22-bit ADC resolution provides high accuracy suitable for regulatory compliance. Consider the available GPIO count and interface options for system connectivity requirements. Evaluate the thermal performance within the specified operating temperature range for the intended environment.

Part Context

This device belongs to the 71M65xx series of metering SoCs from Maxim Integrated, now part of Analog Devices. These chips are designed to reduce bill of materials cost by integrating analog front ends, computation engines, and microprocessors onto a single die. The G variant typically denotes specific pinout or feature configurations within the family.

Replacement Considerations

Check for direct substitutes such as the 71M6533D or 71M6533F if available. Verify pin compatibility and software library support when migrating between variants within the same series.
