78M6613-IM/F

Overview

The 78M6613-IM/F is a metering System on Chip (SoC) from Analog Devices/Maxim Integrated, designed for single-phase power and energy measurement applications. It integrates an 80515 core processor with a maximum clock frequency of 5 MHz, 32 kB Flash program memory, and 2 kB XRAM data RAM. The device features a high-resolution 22-bit ADC and supports UART communication interfaces. Operating at a supply voltage of 3.3 V, it is housed in a QFN-32 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a silicon delay line for precise timing measurements
• Combines high-resolution analog-to-digital conversion with digital signal processing capabilities
• Includes an embedded 80515 microcontroller for system control and metering algorithms

Applications

• Single-phase electricity metering systems
• Power quality monitoring devices
• Smart grid endpoint units

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm the specific suffix variants match design requirements as packaging and environmental ratings may differ. Request current lifecycle status documentation to ensure long-term supply stability for production planning.

Selection Notes

Select this SoC when a compact solution combining high-precision analog front-end processing with digital control logic is required. The integrated 22-bit ADC eliminates external precision components, reducing board space. Ensure the UART interface meets communication needs, as I2C support is not listed for this specific variant compared to other family members.

Part Context

This component belongs to the 78M6613 series of metering SoCs, which are optimized for utility-grade energy measurement. It shares architectural similarities with the 78M6612 but offers a different pin count and interface configuration suitable for smaller form-factor designs. The series leverages Maxim's expertise in mixed-signal integration for utility applications.

Replacement Considerations

Check for 78M6613-IM/F/PW4 as a potential package variant if lead-free or specific tape-and-reel options are needed. Verify compatibility with 78M6612 if more I/O pins are required, noting the difference in package type and interface availability.
