The ADE7518 is a single-phase energy measurement IC with an 8052 MCU, RTC, and LCD driver. It features wide supply voltage operation, ultralow power consumption, and real-time clock mode. It provides high accuracy measurement of active, reactive, and apparent energy.
The ADE7518 integrates an energy‑metering front‑end, a fixed‑function DSP, an enhanced 8052 microcontroller core, a real‑time clock and a 108‑segment LCD driver in a single 64‑lead LQFP package. It provides high‑accuracy active, reactive and apparent energy measurements as well as voltage and current RMS readings, supporting IEC and ANSI metering standards.
The device operates from 2.4 V to 3.7 V, works from –40 °C to +85 °C, and includes programmable gain amplifiers, UART, SPI/I²C, watchdog timer and power‑supply management features for low‑power and battery‑backup operation.
