ADE7169ASTZF16

Overview

The ADE7169ASTZF16 is a single-phase energy measurement integrated circuit from Analog Devices, designed for high-precision metering applications. It integrates an 8052 microcontroller unit (MCU), a real-time clock (RTC), and an LCD driver within a single system-on-chip architecture. The device supports Class 1 meter accuracy standards, ensuring reliable energy measurement performance. It is housed in a 64-pin LQFP package with dimensions of 10x10 mm, suitable for surface mount technology (SMD/SMT) installation. This component serves as a complete solution for single-phase energy metering designs.

Feature Summary

• Integrates an 8052 MCU, RTC, and LCD driver for comprehensive single-phase metering functionality
• Delivers Class 1 meter accuracy for precise energy measurement applications
• Provides a complete system-on-chip solution to simplify design complexity

Applications

• Single-phase energy metering systems
• Smart grid infrastructure monitoring
• Residential and commercial electricity meters

Procurement Notes

Verify the specific suffix F16 against official Analog Devices documentation to confirm exact pinout and configuration variants. Confirm current manufacturing status as availability may vary. Ensure compatibility with required firmware development tools, such as C-language compilers for the integrated 8052 MCU. Validate package integrity upon receipt to prevent damage to the 64-LQFP leads during handling.

Selection Notes

Select this component when a unified solution for single-phase metering is required, eliminating the need for separate MCU and peripheral chips. Consider the integrated LCD driver if display output is necessary without additional interface components. Evaluate the Class 1 accuracy requirement against regulatory standards for the target market. Assess the 8052 MCU capabilities against application processing needs before committing to this SoC architecture.

Part Context

The ADE7169 series belongs to Analog Devices' portfolio of energy metering systems on a chip. These devices are engineered to reduce bill of materials and board space by combining analog front-end measurement capabilities with digital control logic. The ASTZF16 variant specifically denotes the industrial temperature range and lead-free packaging compliant with RoHS directives, fitting into the broader category of precision power management and measurement ICs.

Replacement Considerations

Public sources indicate the ADE7953ACPZ as a similar alternative. Verify functional equivalence regarding MCU integration and LCD driver presence, as the ADE7953 may lack these specific integrated peripherals. Confirm package compatibility and pinout alignment before substitution.
