ADE7116ASTZF8

Overview

The ADE7116ASTZF8 is a single-phase energy metering System on Chip (SoC) manufactured by Analog Devices Inc. It integrates high-precision analog front-end circuitry with an embedded 8052-compatible microcontroller core. The device provides accurate measurement of electrical parameters for utility metering applications. It operates within a supply voltage range of 2.4 V to 3.7 V and supports an internal bipolar switch between regulated and battery inputs. The component features ultra-low power operation modes and includes an integrated Real-Time Clock (RTC) and LCD driver capabilities.

Feature Summary

• Integrates high-accuracy analog-to-digital conversion for single-phase current and voltage measurement
• Includes an embedded 8052 microcontroller core with flash program memory and static RAM
• Supports low-power operation with dedicated power-saving modes for extended battery life
• Features an internal bipolar switch allowing flexible connection between regulated and battery supplies

Applications

• Single-phase residential and commercial energy metering systems
• Smart grid endpoint devices requiring precise active and reactive energy calculation
• Utility meters with integrated display and communication interfaces

Procurement Notes

Verify the specific suffix ZF8 against the manufacturer's official datasheet to confirm pinout, package dimensions, and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the operating temperature range meets the target application requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring integrated MCU and metering functionality in a single package. Consider the 64-pin LQFP package constraints for PCB layout. Evaluate the power consumption characteristics against system battery life requirements. Verify compatibility with existing firmware development tools for the 8052 architecture.

Part Context

The ADE7116 belongs to the ADE71xx series of energy metering SoCs from Analog Devices. These devices are designed to replace discrete solutions by combining precision ADCs with processing cores. The ASTZF8 designation indicates a specific package variant and temperature grade within this product line, targeting cost-sensitive yet high-accuracy metering deployments.

Replacement Considerations

Consult Analog Devices documentation for direct pin-to-pin replacements or functional equivalents within the ADE71xx family. Verify that any substitute maintains the same 8052 core compatibility and peripheral configuration.
