78M6618-M/F/P2

Overview

The 78M6618-M/F/P2 is a Metering System on a Chip (SoC) designed for independent monitoring and measurement of up to eight single-phase AC outlets. It features an 80515 core with a maximum clock frequency of 5 MHz, 128 kB Flash program memory, and 4 kB data RAM. The device includes a 21-bit ADC resolution, operates at 3.3 V, and supports SMD/SMT mounting in a QFN-68 package. It offers 19 I/Os, UART interface, and functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates a 21-bit delta-sigma ADC with a 32-bit compute engine for high-precision energy measurement
Supports independent monitoring of up to eight single-phase AC outlets
Includes an integrated LCD driver and configurable digital I/O for relay control
Provides multiple host interface options including UART and SPI

Applications

Metered power distribution units (PDUs)
Rack enclosures for data centers
Intelligent power strips
Subpanels in grid-friendly digital homes

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Check for obsolescence notices as the product lifecycle may be restricted. Ensure firmware compatibility with existing development tools if customization is required.

Selection Notes

Select this SoC for applications requiring multi-channel single-phase power monitoring with high accuracy. The integrated compute engine and flash memory allow for flexible configuration and post-processing without external microcontrollers. Consider the QFN-68 package size and thermal performance for PCB layout constraints.
