ADE7166ASTZF8-RL

Overview

The ADE7166ASTZF8-RL is a single-phase metering System on Chip (SoC) manufactured by Analog Devices. It integrates an 8052 microcontroller core with real-time clock and LCD driver capabilities alongside energy metering functions. The device operates at a maximum clock frequency of 4 MHz and features 16 kB of Flash program memory and 512 bytes of data RAM. It utilizes an LQFP-64 package with 20 I/O lines and supports UART communication. Designed for operation between -40°C and +85°C, it requires a 3.3 V supply voltage.

Feature Summary

• Integrates an 8052 MCU core with real-time clock and LCD driver functionality within a single chip architecture.
• Provides dedicated single-phase energy metering capabilities suitable for utility applications.
• Includes internal Flash program memory and static RAM for embedded control and data storage.

Applications

• Single-phase residential electricity meters
• Smart grid endpoint devices
