78M6618-MR/F/P2

Overview

The 78M6618-MR/F/P2 is a highly integrated metering system-on-chip designed for independent monitoring and measurement of up to eight single-phase AC outlets. It features an 80515 user MPU core, a 32-bit compute engine, and a 21-bit delta-sigma ADC. The device operates on a 3.3 V supply within a -40°C to +85°C temperature range. It includes 128 kB of internal Flash memory and 4 kB of RAM. Key interfaces include SPI and UART. The component is housed in a SQFN-68 package.

Feature Summary

• Supports independent measurement of up to eight single-phase AC outlets with high integration
• Integrates a 32-bit compute engine and 21-bit delta-sigma ADC for precise energy calculation
• Includes an 80515 microprocessor core with 128 kB Flash for flexible configuration and data processing
• Provides multiple host interface options including SPI and UART for system connectivity

Applications

• Metered power distribution units (PDUs) for data centers
• Intelligent power strips and subpanels for digital homes
• Rack enclosures requiring individual outlet monitoring

Procurement Notes

Verify the specific suffix MR/F/P2 against official Analog Devices documentation to confirm package type and tape-and-reel status. Confirm current product lifecycle status as discontinued or limited availability through authorized channels. Ensure compatibility with existing firmware libraries provided by Teridian for common applications before procurement.

Selection Notes

Select this component for applications requiring multi-outlet energy monitoring with high accuracy over a wide dynamic range. The integrated LCD driver and configurable I/Os support direct display and relay control. Consider the 80515 core for custom firmware development if standard Teridian firmware does not meet specific application requirements.
