78M6612-MR/F/P2

Overview

The 78M6612-MR/F/P2 is a discontinued single-phase metering System on Chip (SoC) from Analog Devices Inc./Maxim Integrated. It integrates an 80515 core processor with 32 kB Flash program memory and 2 kB XRAM data RAM, operating at a maximum clock frequency of 10 MHz. The device features a 22-bit ADC resolution and supports I2C and UART interfaces. It operates on a 3.3 V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in a 68-SQFN (8x8) package with exposed pad for surface mount installation.

Feature Summary

• Integrates high-resolution 22-bit analog-to-digital conversion capabilities for precise energy measurement applications.
• Combines an 80515 microcontroller core with dedicated metering hardware to reduce system complexity.
• Supports standard communication protocols including I2C and UART for flexible system integration.

Applications

• Single-phase electricity metering systems
• Smart grid energy monitoring devices
