Product Details
The ADE5169/ADE5569 integrate the 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 device.The ADE measurement core includes active, reactive, and apparent energy calculations, as well as voltage and current rms measure- ments. This information is accessible for energy billing by using the 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 RTC with a power supply backup pin, an SPI or I2C interface, and two independent UART interfaces. The ready to use information from the ADE core reduces the requirement for program memory size, making it easy to integrate complicated design into 62 kB of flash memory.
The ADE5169 includes a 104-segment LCD driver and the ADE5569 includes a 108-segment LCD driver, each with the capability to store up to four LCD screens in memory. This driver generates voltages capable of driving LCDs up to 5 V.
