Data Sheet
GENERAL DESCRIPTION
The ADE7116/ADE7166/ADE7169/ADE7566/ADE75691
integrate the 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 device.
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 I2C interface, and a UART interface. The ready to use infor-
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/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.
