71M6533H-IGTR/F

Overview

The 71M6533H-IGTR/F is a three-phase energy metering integrated circuit from Analog Devices Inc./Maxim Integrated. It is housed in a 100-LQFP (14x14) package and operates as a System on Chip (SoC). The device integrates an 8051-compatible core with 128 kB of program memory, designed for high-precision power measurement applications.

Feature Summary

• Integrates dedicated hardware for three-phase energy metering calculations
• Combines analog front-end processing with digital signal capabilities
• Includes embedded microcontroller core for system control and communication

Applications

• Three-phase smart electricity meters
• Industrial power monitoring systems
• Energy management sub-metering units

Procurement Notes

Verify the specific suffix H against official datasheets to confirm hardware revision differences. Confirm LQFP-100 pinout compatibility with target PCB layout. Ensure supply chain sources provide original manufacturer documentation for quality assurance.

Selection Notes

Select this component when precise three-phase energy measurement is required within a single chip solution. Evaluate the integration of the MCU core against external processor needs. Consider the 100-pin package constraints for board space and thermal management requirements.

Part Context

This part belongs to the 71M65xx series of metering SoCs. It serves as a specialized alternative to discrete ADC and MCU combinations. The series targets utility-grade metering applications requiring high accuracy and low component count.

Replacement Considerations

Check for 71M6533-IGTR/F or 71M6533H-IGT/F variants. Verify if non-H suffix versions meet specific hardware revision requirements.
