ADE7166ASTZF8

Overview

The ADE7166ASTZF8 is a single-phase energy metering system-on-chip manufactured by Analog Devices Inc. It integrates an 8052 microcontroller core with metering capabilities in a 64-LQFP package. The device operates on a supply voltage range of 2.4 V to 3.7 V and draws a typical supply current of 4 mA. It features an input impedance of 770 kOhm and maintains a measurement error of 0.1%. The component supports I/O voltages of 1.3 V, 2 V, and 2.4 V for high states, and 0.4 V and 0.8 V for low states. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates an 8052 microcontroller core with real-time clock and LCD driver capabilities for single-phase metering applications.

Applications

• Single-phase energy metering systems

Procurement Notes

Verify the specific suffix 'F8' against official documentation to confirm pinout and configuration, as suffixes often denote specific packaging or variant details. Confirm availability status, as this part may be obsolete or restricted. Ensure compatibility with the required 64-LQFP surface mount footprint and verify moisture sensitivity level handling during assembly.

Selection Notes

Select this component for designs requiring a combined MCU and metering solution in a compact form factor. Ensure the application voltage aligns with the 2.4 V to 3.7 V supply range. Consider the 64-LQFP package constraints and the -40°C to +85°C industrial temperature rating when defining the board layout and environmental specifications.

Part Context

The ADE7166 belongs to the ADE71xx series of single-phase metering ICs from Analog Devices. These devices are designed to provide accurate energy measurement while integrating processing power. The ASTZF8 designation indicates a specific commercial/industrial grade variant in the LQFP-64 package, distinct from other suffixes that may offer different memory sizes or interface options.
