4 / 148 page  ADE5166/ADE5169/ADE5566/ADE5569 Preliminary Technical Data Rev. PrB | Page 4 of 148 GENERAL DESCRIPTION The ADE5166/ADE5169/ADE5566/ADE55691 integrate 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 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 full real-time clock with a power supply backup pin, two independent UART interfaces, 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 62 kB of flash memory. The ADE5166/ADE5169/ADE5566/ADE5569 also include a 108-/104-segment LCD driver with the capability to store up to 4 LCD screens in memory. This driver generates voltages capable of driving LCDs up to 5 V. FUNCTIONAL BLOCK DIAGRAMS IP IN VP VN ENERGY MEASUREMENT DSP OSC COM0 ... ...
