ADE7569: 单相电能计量IC，集成8052 MCU、RTC和LCD驱动器

ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 将ADI公司电能（ADE）计量IC模拟前端和固定功能DSP解决方案与增强型8052 MCU内核、RTC、LCD驱动器和所有外设集成为一体，提供一种带液晶显示屏的电表。ADE测量内核包括有功、无功和视在功率计算以及电压和电流均方根值测量。这些信息可通过内置的电能标量直接用于计费目的。电能计量DSP包括许多电力线路监控功能（如SAG、峰值和零交越等），可简化电表设计。微处理器功能包括单周期8052内核、带备用电源引脚的实时时钟、UART以及SPI或I²C® 接口。ADE内核提供直接可用的信息，降低了对程序存储器大小的要求，使得能够轻松将复杂的设计集成到16 kB闪存中。ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 还包括一个108/104段LCD驱动器。在 ADE7166/ADE7169/ADE7566/ADE7569 中，此驱动器产生的电压能够将LCD驱动至最高5 V。

The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 integrate Analog Devices, Inc., energy (ADE) metering IC analog front end and fixed function DSP solution with an enhanced 8052 MCU core, an 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 measurements. 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 real-time clock with a power supply backup pin, a UART, 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 16 kB of flash memory.The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569 also include a 108-/104-segment LCD driver. In theADE7166/ADE7169/ADE7566/ADE7569, this driver generates voltages capable of driving LCDs up to 5 V.
