ADE7566ASTZF16

Overview

The ADE7566ASTZF16 is a single-phase energy metering System on Chip (SoC) manufactured by Analog Devices Inc. It integrates an 8052 microcontroller core with real-time clock and LCD driver capabilities. The device features an 8-bit ADC resolution, 4 MHz maximum clock frequency, and operates at 3.3 V. It includes 16 kB of Flash program memory and 512 B of data RAM. Packaged in a 64-pin LQFP, it supports UART communication and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates single-phase energy metering analog front-end with an 8052 MCU core
• Includes built-in real-time clock and LCD driver functionality
• Supports UART interface for system communication and debugging

Applications

• Single-phase residential energy metering systems
• Smart grid metering applications requiring integrated display drivers
• Utility metering devices utilizing RTC synchronization

Procurement Notes

Verify current availability status as distribution channels may indicate limited supply or discontinuation. Confirm the specific suffix 'F16' matches design requirements, as package and temperature variants exist within the ADE7566 family. Ensure compatibility with existing PCB footprints for the LQFP-64 package before finalizing procurement plans.

Selection Notes

Select this component when a combined metering IC and MCU solution is required to reduce bill of materials. The integrated LCD driver eliminates external display controller needs. Verify that the 8052 architecture and 4 MHz speed meet processing demands for single-phase calculations and display updates.

Part Context

The ADE7566 belongs to Analog Devices' dedicated metering SoC portfolio designed for utility applications. It consolidates analog measurement, digital processing, and user interface control into a single silicon die. This integration simplifies board layout and reduces component count compared to discrete MCU and metering IC combinations.

Replacement Considerations

Consult official documentation for qualified replacements within the ADE7566 series. Substitutes must match the LQFP-64 package and 8052 core architecture. Verify pinout compatibility and electrical specifications against the target application requirements.
