Overview
The ADE7156ASTZF8 is a single-phase energy metering integrated circuit manufactured by Analog Devices Inc. It is housed in a 64-lead LQFP package measuring 10x10 mm. The device integrates an 8052 microcontroller, real-time clock (RTC), and LCD driver capabilities alongside high-precision analog-to-digital conversion for energy measurement applications.
Feature Summary
- Integrates an 8052 microcontroller core with real-time clock functionality
- Includes built-in LCD driver support for direct display interfacing
- Provides high-accuracy single-phase energy measurement capabilities
Applications
- Single-phase electricity metering systems
- Smart grid monitoring devices
- Energy management units requiring integrated MCU and display drivers
Procurement Notes
Verify the specific suffix F8 against official Analog Devices documentation to confirm pinout and thermal specifications. Ensure compatibility with existing PCB layouts designed for the 64-LQFP package. Confirm that the integrated 8052 architecture aligns with your firmware development tools and memory requirements before procurement.
Selection Notes
Select this component when a combined solution for energy metering, processing, and display is required. It eliminates the need for external MCU and LCD driver chips. Consider the 64-LQFP footprint constraints and verify that the internal 8052 instruction set meets your application's computational needs without external processing overhead.
Part Context
This part belongs to the ADE7156 family of single-phase energy metering ICs from Analog Devices. It is designed to simplify system design by integrating analog front-end, digital signal processing, and control logic into a single package, reducing bill of materials and board space compared to discrete solutions.
Replacement Considerations
Check for ADI-approved alternatives within the same family or newer revisions. Verify pin-to-pin compatibility if substituting with other ADE7156 variants. No public cross-reference data confirms direct substitutes from other manufacturers.
