GENERAL DESCRIPTION

The ADE7169F16 integrates Analog Devices Energy (ADE) Metering IC analog front end and fixed function DSP solution with

an enhanced 8052 MCU core, a RTC, an LCD driver and all the peripherals to make an electronic energy meter with LCD

display with a single part.

The ADE Energy Measurement core includes Active, Reactive, Apparent Energy calculations, as well as voltage and current rms

measurements. This information is ready to use for energy billing by using built-in energy scalars. Many power line

supervisory features like SAG, Peak, Zero-crossing are also included in the energy measurement DSP to simplify energy meter

design.

The microprocessor functionality includes a single cycle 8052 core, a Real Time Clock with a power supply back-up pin, a

UART, and a SPI or I

requirement thus making it easy to integrate complicated design in 16k Bytes of Flash memory.

The ADE7169F16 also includes a 104-segment LCD driver. This driver generates voltages capable of driving 5V LCDs.
