The ADE7518 is a single-phase energy measurement IC that integrates an analog front end, a digital signal processing (DSP) solution, and an enhanced 8052 microcontroller core. It is designed to simplify the design of electronic energy meters with LCD displays by providing active, reactive, and apparent energy calculations, along with voltage and current RMS measurements. The device includes a real-time clock (RTC), an LCD driver, and various peripherals such as UART, SPI, and I2C interfaces.
