ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
GENERAL DESCRIPTION
The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569
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.
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 real-time clock with a power supply backup pin, an SPI
or I
mation from the ADE core reduces the program memory size
requirement, making it easy to integrate complicated design
into 16 kB of flash memory.
The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569 also include a 108-/104-segment LCD driver. In the
ADE7166/ADE7169/ADE7566/ADE7569, this driver generates
voltages capable of driving LCDs up to 5 V.
