ADE7518ASTZF16

Overview

The ADE7518ASTZF16 is a single-phase energy metering integrated circuit manufactured by Analog Devices Inc. It integrates an 8052 microcontroller, real-time clock (RTC), and LCD driver capabilities within a 64-LQFP package measuring 10x10 mm. The device operates on a supply voltage ranging from 2.4V to 3.7V with I/O levels of 0.4V low and 2V high. Key electrical specifications include an input impedance of 770 kOhm, a measurement error of 0.1%, and a supply current of 4mA. It supports an operating temperature range from -40°C to specified maximums.

Feature Summary

• Integrates an 8052 microcontroller for local processing and control logic
• Includes built-in real-time clock functionality for time-stamped data logging
• Features dedicated hardware drivers for direct LCD interface connections

Applications

• Single-phase residential energy metering systems
• Smart grid endpoint devices requiring integrated MCU capabilities
• Utility-grade electricity meters with display output requirements

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'F16' matches project requirements as it denotes particular configuration or revision details. Check for obsolete status indicators in current catalogs, as availability may be limited. Ensure environmental compliance documentation aligns with regional regulations before integration into final products.

Selection Notes

Select this component when a single-phase metering solution requires embedded processing without external MCU overhead. The integrated RTC and LCD driver reduce bill-of-materials complexity compared to discrete solutions. Evaluate thermal performance within the 64-LQFP package constraints. Consider the 0.1% measurement error specification against regulatory accuracy classes required for the target application environment.
