NEW DESIGNS:
ADE7569 Single-Phase Energy Measurement IC with 8052 MCU, RTC, and LCD Driver

The ADE75181 integrates 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 part.

The ADE measurement core includes active, reactive, and apparent energy calculations, as well as voltage and current rms measurements. This information is ready to use for energy billing by using 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, 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 ADE7518 also includes a 108-segment LCD driver. This driver generates waveforms capable of driving LCDs up to 3.3 V.
