78M6610+PSD/B02T

Overview

The 78M6610+PSD/B02T is a single-phase energy measurement processor from the 78M6610 series, manufactured by Analog Devices Inc. (Maxim Integrated). It integrates an EMP signal processing core with 8 kB of internal Flash memory and 1.5 kB of RAM. The device operates on a 3.3 V supply and supports I2C, SPI, and UART interfaces. It features two voltage and two current sensor inputs, an on-chip temperature sensor, and an optional external oscillator. Packaged in a QFN-24 format, it is designed for precise metering applications.

Feature Summary

• Integrates dedicated EMP signal processing core for energy measurement tasks
• Supports multiple communication protocols including I2C, SPI, and UART
• Includes on-chip temperature sensing capabilities
• Handles dual voltage and dual current sensor inputs

Applications

• Single-phase electricity metering systems
• Power supply unit monitoring
• DC energy measurement devices

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity and RoHS compliance before integration. Check for obsolescence notices as availability may be limited. Ensure design compatibility with existing firmware architectures supporting the EMP core.

Selection Notes

Select this model for single-phase applications requiring integrated signal processing without a user MPU. Compare against variants like +LMU or +PSD based on specific interface needs and packaging requirements. Consider the absence of an internal ADC if external conversion is preferred.

Part Context
