The ADE Energy Measurement core includes Active, Reactive, 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 like SAG, Peak, Zero-crossing are also 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 back-up pin, a UART, and a SPI or I2C interface. The ready to use information from the ADE core reduces the program memory size requirement thus making it easy to integrate complicated design in 16k Bytes of Flash memory. The ADE75xx/ADE71xx also includes a 108/104-segment LCD driver respectively. This driver generates voltages capable of driving 5V LCDs. |
