71M6533-IGTR/F

Overview

The 71M6533-IGTR/F is a single-phase metering System on Chip (SoC) from 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 and supports I2C and UART interfaces. Operating at 3.3 V, it utilizes an LQFP-100 package with 39 I/O pins. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates an 80515-compatible MPU core for efficient processing
• Features Single Converter Technology with a 22-bit delta-sigma ADC
• Includes low-power RTC with digital temperature compensation
• Supports field programmable flash memory for code and data

Applications

• Residential electricity meters
• Smart grid metering systems
• Single-phase energy monitoring devices

Procurement Notes

Verify current availability as Mouser indicates restricted supply or discontinuation status for this specific part number. Confirm RoHS compliance details, as listed specifications show conflicting data regarding lead-free status. Ensure the ordering suffix matches the required tape and reel packaging format for surface mount assembly.

Selection Notes

Select this SoC for applications requiring high integration and precision in single-phase metering. The 10 MHz core speed offers enhanced processing capabilities compared to lower-frequency variants. Verify that the 128 kB Flash size meets application firmware requirements. Ensure compatibility with the LQFP-100 footprint during PCB layout design.

Part Context

This component belongs to the Teridian 71M6x01 series of fourth-generation single-phase metering SoCs. It shares architectural similarities with models like the 71M6541 and 71M6542 but differs in specific memory configurations and core clock speeds. The series is designed to reduce bill-of-materials costs through high integration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other members of the 71M65xx family, such as the 71M6532F, if pinout and memory specifications align with design requirements.
