GENERAL DESCRIPTION
The ADE5166/ADE5169/ADE5566/ADE5569
1
integrate the
Analog Devices, Inc., 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
2
C interface,
and two independent UART interfaces. The ready-to-use infor-
mation 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 and
the ADE5566/ADE5569 include a 108-segment LCD driver, each
with the capability to store up to four LCD screens in memory. This
driver generates voltages capable of driving LCDs up to 5 V.
32 KB FLASH OPTION
A reduced memory version of the ADE5169 is available with
32 kB of flash memory. A description of the flash memory
organization of this model is provided in the Flash Memory
Organization for the 32 kB Model section. All other features
and functionality are identical between the models and no
reference is made in the remainder of this data sheet to the
32 kB model. If using the 32 kB model, 32 kB should therefore
be substituted in any references to 62 kB of flash memory.
