• Description: Single-Phase Energy Measurement IC with 8052 MCU, RTC, and LCD Driver
• Manufacturer: AD [Analog Devices]

ADE5166/ADE5169
GENERAL DESCRIPTION
The ADE5166/ADE5169
energy (ADE) metering IC analog front end and fixed function
DSP solution with an enhanced 8052 MCU core, a full RTC, an
LCD driver, and all the peripherals to make an electronic energy
meter with an LCD display in a single part.
The ADE measurement core includes active, reactive, and apparent
energy calculations, as well as voltage and current rms measure-
ments. This information is accessible for energy billing by using the
built-in energy scalars. Many power line supervisory features such
as SAG, peak, and zero crossing are included in the energy
measurement DSP to simplify energy meter design.

The microprocessor functionality includes a single-cycle 8052 core,
a full RTC with a power supply backup pin, an SPI or I
interface, and two independent UART interfaces. The ready-to-
use information from the ADE core reduces the requirement for
program memory size, making it easy to integrate complicated
design into 62 kB of flash memory.
The ADE5166/ADE5169 include a 104-segment LCD driver with
the capability to store up to four LCD screens in memory. This
driver generates voltages capable of driving LCDs up to 5 V.
