Procurement Notes

Verify component status as the ADE5166ASTZF62 is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets if replacement is required. Ensure compatibility with existing PCB layouts and firmware environments designed for this specific SoC variant before procurement decisions are finalized.

Selection Notes

Select this component for applications requiring integrated single-phase metering with embedded processing and display driving capabilities. Consider the 8052 architecture compatibility and available development tools such as the EVAL-ADE5169EBZ-2 kit for prototyping. Evaluate thermal performance within the specified operating temperature range and ensure interface requirements match the UART connectivity provided.

Part Context

This part belongs to the ADE516x family of metering SoCs from Analog Devices, designed for utility-grade energy measurement. It shares architectural similarities with related models like the ADE5169, offering comparable integration levels for single-phase applications. The family targets cost-effective, space-constrained metering solutions requiring precise analog-to-digital conversion and digital signal processing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, engineering teams should evaluate alternative metering SoCs from the same manufacturer or compatible third-party solutions that meet the required electrical specifications and pinout constraints.
