ADE5569: 单相电能计量IC,集成8052 MCU、RTC和LCD驱动器

ADE5569 功能框图The ADE5166/ADE5169/ADE5566/ADE5569 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、完整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。利用内置的电能标量可以访问这些信息,以便进行计费。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、带备用电源引脚的完整RTC、SPI或I2C®接口以及2个独立的UART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62 kB闪存中。微处理器功能包括单周期8052内核、带备用电源引脚的完整RTC、SPI或I2C®接口以及2个独立的UART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62 kB闪存中.

The ADE5166/ADE5169/ADE5566/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 part.The ADE measurement core includes active, reactive, and apparent energy calculations, as well as voltage and current rms measurements. 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 ADE5166/ADE5169 include a 104-segment LCD driver and the ADE5566/ADE556 9include 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.
