78M6610+LMU/B01

Overview

The 78M6610+LMU/B01 is a single-phase energy measurement processor manufactured by Analog Devices Inc./Maxim Integrated. It features an EMP signal processing core with no user MPU, operating at a maximum clock frequency of 20 MHz. The device includes 8 kB of Flash program memory and 1.5 kB of data RAM. It supports I2C, SPI, and UART interfaces and operates on a 3.3 V supply voltage within a temperature range of -40°C to +85°C. The component is housed in a QFN-24 package.

Feature Summary

• Integrates an Energy Measurement Processor (EMP) core for dedicated signal processing without a user-accessible microprocessor unit.
• Provides multiple communication options including I2C, SPI, and UART interfaces for system connectivity.
• Includes internal non-volatile Flash memory and static RAM for code storage and data handling.

Applications

• Single-phase AC power metering systems
• Energy measurement processors in utility infrastructure
• Smart grid monitoring devices

Procurement Notes

Verify the current product status as this specific part number may be discontinued or subject to limited availability from distributors. Confirm the manufacturer designation, as some sources list Silergy while others cite Analog Devices/Maxim Integrated. Ensure the QFN-24 package type matches your PCB footprint requirements before ordering.

Selection Notes

Select this component for applications requiring a dedicated single-phase energy measurement solution without the complexity of a general-purpose MPU. The absence of an integrated ADC indicates it requires external sensor conditioning. Verify compatibility with the required interface protocols and ensure the 3.3 V supply voltage aligns with the system design constraints.

Part Context

This component belongs to the 78M6610 series of metering systems on a chip. It is designed specifically for single-phase energy measurement applications. The series typically integrates specialized cores for accurate power calculation and data management in utility-grade metering environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check with the manufacturer for end-of-life notifications or recommended alternative components within the same family if this part is discontinued.
