78M6610+LMU/B01T

Overview

The 78M6610+LMU/B01T is a single-phase energy measurement processor System-on-Chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes the EMP signal processing core and operates on a 3.3 V supply voltage within an industrial temperature range of -40°C to +85°C. The device integrates 8 kB of internal Flash program memory and 1.5 kB of data RAM. Communication interfaces include I2C, SPI, and UART. It is housed in a QFN-24 package.

Feature Summary

• Integrates an Energy Measurement Processor (EMP) core for dedicated signal processing tasks without a user MPU.
• Provides flexible host connectivity through multiple standard serial communication protocols.
• Includes on-chip timing capabilities with a dedicated timer/counter module.

Applications

• Single-phase energy metering systems
• Power supply unit (PSU) monitoring
• DC power measurement applications

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the specific suffix matches required packaging or qualification standards. Check current availability status as distribution may vary. Ensure design compatibility with the specified 3.3 V operating voltage and interface requirements.

Selection Notes

Select this component for single-phase applications requiring a dedicated measurement processor rather than a general-purpose microcontroller. It is suitable where integrated EMP functionality simplifies firmware development compared to solutions requiring external ADCs or separate processors.

Part Context

This part belongs to the 78M6610 series of metering SoCs. It shares the core EMP architecture with variants like the 78M6610+LMU but differs in packaging and manufacturing lot specifications indicated by the B01 suffix. It serves as a specialized solution for cost-sensitive single-phase energy monitoring.
