71M6545HT-IGTR/F

Overview

The 71M6545HT-IGTR/F is a Metering System on a Chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 80515 core with a maximum clock frequency of 10 MHz, 128 kB Flash program memory, and 4 kB data RAM. The device features a 22-bit ADC resolution, operates at 3.3 V, and supports I2C and UART interfaces. Packaged in LQFP-100, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates high-resolution metrology processing with embedded microcontroller capabilities
• Supports digital communication via standard serial interfaces for system integration
• Designed for surface-mount assembly in compact metering form factors

Applications

• Single-phase energy metering systems
• Smart grid metering infrastructure
• Precision power monitoring devices

Procurement Notes

Verify current availability status as supply may be limited or restricted. Confirm RoHS compliance requirements against specific project standards. Ensure the LQFP-100 package dimensions match PCB layout constraints. Validate operating temperature range suitability for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a combined analog-to-digital conversion and processing unit is required for single-phase applications. The 22-bit resolution supports high-accuracy measurement needs. Consider the 80515 core compatibility if existing firmware architectures are utilized. Evaluate the 10 MHz clock speed against real-time processing demands.

Part Context

This part belongs to the 71M65xx series of Metering Systems on a Chip from Maxim Integrated, now under Analog Devices. These SoCs typically integrate precision analog front-ends with digital processing cores to reduce bill-of-materials costs in energy metering designs by minimizing external component counts.
