Cypress CY3269N照明解決方案

1、cypress cy3269n照明解決方案 公司的cy3269n照明開發(fā)計(jì)劃采納cy8c04 ez-color hb led 控制器,用來開發(fā)智能的led照明,用戶采納手指觸摸能開發(fā)出從囫圇房間到大型建造物的照顯然示,具有暖色,中色或冷白光的可變顏色溫度,目標(biāo)應(yīng)用在背光,通用照明,建造物照明和大型顯示屏等.本文介紹了cy8cled04 hb led 控制器主要特性,規(guī)律框圖,以及cy3269n照明開發(fā)套件,開發(fā)板和材料清單. cypresss ez-color family of devices offers the ideal control solution for high bright

2、ness led applications requiring intelligent dimming control. ez-color devices combine the power and flexibility of programmable system-on-chip (p with cypresss precise illumination signal modulation (prism ) modulation technology providing lighting designers a fully customizable and integrated light

3、ing solution platform.the ez-color family supports a range of independent led channels from 4 channels at 32 bits of resolution each, up to 16 channels at 8 bits of resolution each. this enables lighting designers the flexibility to choose the led array size and color quality. designer software, wit

4、h lighting specific drivers, can significantly cut development time and simplify implementation of fixed color points through temperature, optical, and led binning compensation. ez-colors virtually limitless analog and digital customization enable simple integration of features in addition to intell

5、igent lighting, such as capsense, battery charging, image stabilization, and motor control during the development process. these features, along with cypresss best-in-class quality and design support, make ez-color the ideal choice for intelligent hb led control applications.cy8cled04主要特性: hb led co

12、 a cpu, memory, clocks, and configurable general purpose i/o (gpio).the m8c cpu core is a powerful processor with speeds up to 68 mhz, providing a four 8-bit harvard-architecture microprocessor. the cpu uses an interrupt controller with up to 20 vectors, to simplify programming of real time embedded

13、 events. program execution is timed and protected using the included sleep and watchdog timers (wdt).memory encompasses 16k of flash for program storage, 1k of sram for data storage, and up to 2k of eeprom emulated using the flash. program flash uses four protection levels on blocks of 64 bytes, all

14、owing customized software ip protection.the ez-color family incorporates flexible internal clock generators, including a 24 mhz internal main oscillator (imo) accurate to 8 percent over temperature and voltage. the 24 mhz imo can also be doubled to 48 mhz for use by the digital system.a low power 32

15、 khz internal low speed oscillator (ilo) is provided for the sleep timer and wdt. the clocks, together with programmable clock dividers (as a system resource), provide the flexibility to integrate almost any timing requirement into the ez-color device. in usb systems, the imo self-tunes to ± 0.25% accuracy for usb communication.ez-color gpios provide connection to the cpu, digital and analog re
