发布时间:2020-07-21 18:05:09 阅读: 来源:卸扣厂家

Cypress 公司的CY8CLED16 EZ-Color系列是HBLED控制器,支持高达16路LED通路,每路的分辨率高达32位.M8C处理器工作速度高达24MHz,工作电压3.0V-5.25V,材用片内的开关模式泵可使电压低至1.0V,工作温度从-40度到85度C. CY8CLED16具有灵活的接口,可编程的引脚配置,以及灵活的片上存储器,主要应用在LCD背景光,通用照明,建筑物照明,照相机/手机闪光等.本文介绍了CY8CLED16主要特性,方框图, 数字系统和模拟系统方框图, 4路LED演示板电路图和所用材料清单.Cypress EZ-Color family of devices offers the ideal control solution for High Brightness LED applications requiring intelligent dimming control. EZ-Color devices combine the power and flexibility of PSoC (Programmable System-on-Chip?); with Cypress PrISM (precise illumination signal modulation) modulation technology providing lighting designers a fully customizable and integrated lighting solution e EZ-Color family supports up to 16 independent LED channels with up to 32 bits of resolution per channel, enabling lighting designers the flexibility to choose the LED array size and color quality. PSoC Express software, with lighting specific drivers, can significantly cut development time and simplify implementation of fixed color points through temperature and LED binning compensation. EZ-Colors virtually limitless analogand digital customization allow for simple integration of features in addition to intelligent lighting, such as Battery Charging, Image Stabilization, and Motor Control during the development process. These features, along with Cypress best-in-class quality and design support, make EZ-Color the ideal choice for intelligent HB LED control 8CLED16主要特性:■ HB LED ControllerConfigurable Dimmers Support up to 16 Independent LED Channels8-32 Bits of Resolution per ChannelDynamic Reconfiguration Enables LED Controller plus other Features; BatteryCharging, Motor Control…■ Visual Embedded Design, PSoC ExpressLED Based Express Drivers?
