ADE7566ASTZF8

Overview

The ADE7566ASTZF8 is a single-phase energy metering system-on-chip manufactured by Analog Devices Inc. It integrates an 8052 microcontroller core with real-time clock and LCD driver capabilities within a 64-LQFP package. The device operates on a supply voltage range of 2.4 V to 3.7 V, drawing a typical supply current of 4 mA. It features an input impedance of 770 kOhm and supports I/O voltages of 1.3 V, 2 V, and 2.4 V for high levels, and 0.4 V and 0.8 V for low levels. The component achieves a measurement error of 0.1% and functions reliably across an operating temperature range of -40°C to 85°C.

Procurement Notes

Verify the current part status before procurement as this specific variant may be obsolete or restricted. Confirm that the 64-LQFP package dimensions match your PCB footprint requirements. Ensure compatibility with the required 2.4 V to 3.7 V supply voltage range for your target application environment. Check for moisture sensitivity level constraints during storage and handling procedures.

Selection Notes

Select this component when a combined analog front-end and microcontroller solution is required for single-phase metering. Consider the 64-LQFP package size and surface mount mounting type for board layout planning. Evaluate the 8052 core capabilities against your firmware complexity needs. Verify that the integrated LCD driver meets your display interface requirements without external drivers.
