ADE7166ASTZF16-RL

Overview

The ADE7166ASTZF16-RL is a single-phase metering System on Chip (SoC) manufactured by Analog Devices Inc. It integrates an 8052 microcontroller core with real-time clock and LCD driver capabilities alongside analog front-end functions. Key electrical parameters include a maximum clock frequency of 4 MHz, 16 kB of Flash program memory, and 512 bytes of data RAM. The device features an 8-bit ADC resolution and operates within a supply voltage range of 3.3 V. It supports UART communication interfaces and provides 20 general-purpose I/O pins. The component is housed in a 64-pin LQFP package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates single-phase energy metering functions with an embedded 8052 microcontroller
• Includes dedicated hardware for Real-Time Clock (RTC) operations and LCD driving
• Combines analog signal processing with digital control logic on a single silicon die

Applications

• Single-phase residential electricity meters
• Smart grid metering infrastructure
• Energy monitoring systems requiring integrated display drivers

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability through standard distribution channels is currently restricted or non-existent. Verification of current stock status from authorized distributors is required before design finalization. Engineers should assess long-term supply risks and consider redesign strategies due to the discontinued production status.

Selection Notes

Select this part only if legacy compatibility with existing 8052-based designs is mandatory. The integration of RTC and LCD drivers reduces external component count for basic metering applications. Verify that the 4 MHz clock speed and 8-bit ADC resolution meet the specific accuracy and throughput requirements of the target application.

Part Context

The ADE7166 belongs to the ADE7166 series of single-phase metering SoCs from Analog Devices. These devices are designed to simplify the design of single-phase energy meters by combining high-precision analog measurement with digital processing capabilities. The series targets cost-sensitive applications where integrated control and display functions reduce overall system complexity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components require separate verification against functional specifications and pinout compatibility.
