Data Sheet ADE5169/ADE5569 GENERAL DESCRIPTION
The ADE5169/ADE55691 integrate the Analog Devices, Inc., The microprocessor functionality includes a single cycle 8052 core, energy (ADE) metering IC analog front end and fixed function a full RTC with a power supply backup pin, an SPI or I2C interface, DSP solution with an enhanced 8052 MCU core, a full RTC, an and two independent UART interfaces. The ready to use infor- LCD driver, and all the peripherals to make an electronic energy mation from the ADE core reduces the requirement for program meter with an LCD display in a single device. memory size, making it easy to integrate complicated design into The ADE measurement core includes active, reactive, and apparent 62 kB of flash memory. energy calculations, as well as voltage and current rms measure- The ADE5169 includes a 104-segment LCD driver and the ments. This information is accessible for energy billing by using the ADE5569 includes a 108-segment LCD driver, each with the built-in energy scalars. Many power line supervisory features such capability to store up to four LCD screens in memory. This driver as SAG, peak, and zero crossing are included in the energy generates voltages capable of driving LCDs up to 5 V. measurement DSP to simplify energy meter design. 1 Patents pending.
