78M6610+PSU/C00

Overview

The 78M6610+PSU/C00 is a single-phase energy measurement processor manufactured by Analog Devices Inc. (Maxim Integrated). It integrates an Energy Measurement Processor (EMP) core with 32 kB of internal Flash memory and 2 kB of data RAM. The device operates on a 3.3 V supply voltage and features a 22-bit ADC resolution for precise metering applications. It supports UART communication interfaces and includes an on-chip temperature sensor. The component is housed in a QFN-32 package and functions as a standalone system-on-chip solution for power supply monitoring.

Feature Summary

• Integrates an EMP core for dedicated signal processing
• Includes built-in diagnostic capabilities for power systems
• Supports firmware customization via internal Flash memory

Applications

• Power supply unit (PSU) monitoring
• DC power distribution systems
• Energy metering devices

Procurement Notes

Verify the specific suffix C00 against official datasheets to confirm pinout and firmware configuration, as suffixes often denote specific board revisions or software variants. Confirm availability status as this series may have limited stock or obsolescence notices from distributors. Ensure compatibility with existing PCB layouts when sourcing replacements.

Selection Notes

Select this component for applications requiring low-cost, high-accuracy single-phase energy measurement without a separate MPU. It is suitable for designs needing integrated diagnostics and firmware flexibility. Compare with the 78M6610+LMU variant if I2C/SPI interfaces are preferred over UART. Verify that the QFN-32 package fits the thermal and spatial constraints of the target enclosure.

Part Context

This part belongs to the 78M6610 family of metering SoCs designed for cost-effective energy monitoring. It complements other variants like the +PSD and +LMU models, which offer different interface options or packaging styles. The family targets industrial and utility metering applications where accurate power tracking and system diagnostics are critical for operational efficiency.
