ADE5166ASTZF62-RL

Overview

The ADE5166ASTZF62-RL is a single-phase metering IC from Analog Devices Inc., housed in a 64-LQFP (10x10) package. It integrates an 8052 microcontroller core, real-time clock (RTC), and LCD driver capabilities. The device operates on a supply voltage range of 2.4 V to 3.7 V with a typical supply current of 4.4 mA. Key electrical parameters include an input impedance of 770 kΩ and a measurement error of 0.1%. It supports I/O voltages of 1.3V, 2V, and 2.4V for high levels, and 0.4V and 0.8V for low levels. The component functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates an 8052 microcontroller core with real-time clock functionality
• Includes dedicated hardware for LCD driving
• Provides single-phase metering with integrated analog-to-digital conversion

Applications

• Single-phase electricity metering systems
• Smart grid energy monitoring devices
• Utility metering applications requiring integrated MCU and display control

Procurement Notes

Verify the specific suffix '62' against the manufacturer's official documentation to confirm pinout, packaging, and environmental compliance details. Confirm availability status as the base part number may have discontinued variants. Ensure the reel format matches the '-RL' designation if continuous tape feeding is required for assembly processes.

Selection Notes

Select this component for designs requiring a consolidated solution for single-phase metering that combines signal conditioning, data processing, and user interface output. The integrated 8052 core reduces external component count compared to separate MCU and metering ASIC approaches. Verify that the 64-LQFP footprint and thermal characteristics align with the target PCB layout constraints.

Part Context

The ADE5166 belongs to Analog Devices' family of single-phase metering ICs designed for utility applications. It serves as a system-on-chip solution by combining precision analog front-end circuitry with digital processing capabilities. This integration simplifies the design of compliant energy meters by handling both measurement accuracy and system control tasks within a single package.
