Rev. A | Page 4 of 144
GENERAL DESCRIPTION
The ADE7566/ADE7569/ADE7166/ADE71691 integrate Analog
Devices, Inc., energy (ADE) metering IC analog front end and
fixed function DSP solution with an enhanced 8052 MCU core,
an RTC, an LCD driver, and all the peripherals to make an
electronic energy meter with an LCD display in a single part.
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 real-time clock with a power supply backup pin, a UART, and an
SPI or I2C® interface. The ready-to-use information from the
ADE core reduces the program memory size requirement, making
it easy to integrate complicated design into 16 kB of flash
memory.
The ADE measurement core includes active, reactive, and apparent
energy calculations, as well as voltage and current rms measure-
ments. This information is ready to use for energy billing by using
built-in energy scalars. Many power line supervisory features
The ADE7566/ADE7569/ADE7166/ADE7169 also include a
108-/104-segment LCD driver. This driver generates voltages
capable of driving LCDs up to 5 V.
