Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as PSU variants often denote specific evaluation or packaging configurations rather than functional differences. Confirm availability status as many 78M6610 derivatives are discontinued or restricted. Ensure compatibility with existing board layouts by checking the QFN-24 pinout and thermal pad requirements specified in the datasheet.

Selection Notes

Select this component when designing single-phase metering solutions requiring integrated analog and digital processing. Compare against other 78M6610 variants based on required memory size, interface availability, and package type. Consider the 20 MHz operating speed and 3.3 V supply constraints during system architecture planning. Evaluate alternative packages if higher pin counts or different thermal profiles are needed.

Part Context

This part belongs to the 78M6610 family of energy metering processors manufactured by Analog Devices under the Maxim Integrated brand. These SoCs are engineered specifically for utility metering applications, combining high-accuracy analog measurement capabilities with robust digital processing cores.
