78M6612-GT/F/P2

Overview

The 78M6612-GT/F/P2 is a single-phase metering System on Chip (SoC) manufactured by Analog Devices Inc. It integrates an 80515 core processor with 32 kB Flash program memory and 2 kB XRAM data RAM. The device features a 22-bit ADC resolution and supports a maximum clock frequency of 10 MHz. It operates at 3.3 V within a temperature range of -40°C to +85°C. Connectivity includes I2C and UART interfaces, with 18 I/O pins available in an LQFP-64 package.

Feature Summary

• Integrates high-resolution 22-bit analog-to-digital conversion for precise energy measurement
• Combines an 80515 microcontroller core with non-volatile flash memory for standalone operation
• Supports standard serial communication protocols including I2C and UART for system integration

Applications

• Single-phase electricity metering systems
• Energy monitoring devices
• Smart grid endpoint hardware

Procurement Notes

Verify component authenticity through authorized channels as the part status is discontinued. Confirm package integrity and lead time constraints due to limited availability. Ensure design-in compatibility with existing firmware architectures before procurement. Check for alternative sourcing options given the end-of-life status.

Selection Notes

Select this component for applications requiring integrated metering and processing in a single-phase environment. Consider the LQFP-64 package size and 18 I/O count for board layout. Evaluate the 10 MHz clock speed against real-time processing requirements. Verify interface compatibility with downstream communication modules.

Part Context

This SoC belongs to the 78M6612 series designed for utility metering. It consolidates analog front-end signal conditioning and digital processing. The family targets cost-sensitive single-phase applications. Integration reduces bill-of-materials complexity compared to discrete solutions.
