71M6511H-IGTR/F

Overview

The 71M6511H-IGTR/F is a single-phase energy metering System on Chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 80515 core with 32 kB of Flash program memory and 2 kB of data RAM, operating at a maximum clock frequency of 5 MHz. The device features a 21-bit ADC resolution and supports I2C and UART interfaces. It operates within a supply voltage range of 3 V to 3.6 V and is housed in a 64-LQFP package.

Feature Summary

• Integrates an 80515 processor core with dedicated metering capabilities for single-phase applications.
• Features high-resolution analog-to-digital conversion for precise energy measurement.
• Includes non-volatile Flash memory for program storage and volatile RAM for data handling.

Applications

• Single-phase residential energy metering systems
• Smart grid endpoint devices
• Precision power monitoring modules

Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm RoHS compliance status and lead-free packaging specifications against the latest datasheet. Ensure the LQFP-64 footprint matches your PCB design requirements. Check for any specific ordering suffixes that may affect temperature range or packaging format before finalizing procurement.

Selection Notes

Select this SoC for single-phase metering designs requiring integrated processing and high-precision ADC. Compare memory sizes and interface options against similar models like the 71M6513 if multi-phase support is needed. Verify that the 5 MHz clock speed and 3.3 V logic levels align with system constraints. Consider the 64-LQFP package size for board layout limitations.
