Overview
The 71M6521DE-IGTR/F is a Metering System on a Chip (SoC) designed for single-phase and dual-phase energy metering applications. It integrates an 80515 core processor with 64 kB of Flash program memory and 2 kB of data RAM. The device features a 22-bit ADC resolution, operates at a maximum clock frequency of 5 MHz, and supports I2C and UART interfaces. It functions within a 3.3 V supply voltage range and is housed in a 64-LQFP (10x10) package.
Feature Summary
- Integrates an 80515 microcontroller core with dedicated metering capabilities
- Features high-resolution analog-to-digital conversion for precise measurement
- Supports standard communication protocols including I2C and UART
Applications
- Single-phase residential energy metering systems
- Dual-phase energy metering applications
- Smart grid metering infrastructure
Procurement Notes
Verify the specific suffix 'DE' against official Analog Devices documentation to confirm pinout and feature set variations. Confirm the manufacturer status as Analog Devices following the Maxim Integrated acquisition. Ensure the 64-LQFP package type matches your PCB design requirements before ordering.
Selection Notes
Select this component for applications requiring integrated MCU and metering functionality in a compact form factor. Consider the 22-bit ADC resolution and 5 MHz processing speed for required accuracy and throughput. Verify interface compatibility with existing system buses and ensure the operating temperature range meets environmental specifications.
Part Context
This part belongs to the Maxim Integrated (now Analog Devices) Metering Systems on a Chip family. These devices combine analog front-end signal conditioning with digital processing cores to simplify energy meter designs. The series targets utility-grade metering solutions with integrated firmware support.
Replacement Considerations
Consult Analog Devices official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering other models in the 71M65xx series or competing metering SoCs.
