一、I~2C总线彩电中的E~2PROM 1.E~2PROM及其特点 E~2PROM是可在线电擦除和电写入的存储器。是I~2C总线控制系统中不可或缺少的被控器,通常与系统控制微处理器成套挂在各机型中的I~2C总线上。其特点是体积小,接口简单,数据保存可靠,可在线改写、功耗低且为低电压写入。 2.E~2PROM在I~2C总线彩电中的作用在I~2C总线彩电中,E~2PROM存储器不仅要存储节目预选数(包括调谐电压、波段等)、音量、对比度、亮度、色饱和度等一些模拟量控制数据,还要存储各被控
First, I ~ 2C bus color TV E ~ 2PROM 1.E ~ 2PROM and its characteristics E ~ 2PROM is electrically erasable and electrically writeable memory. I ~ 2C bus control system is an indispensable controller, usually with the system control microprocessor complete set hanging in the I ~ 2C bus in each model. It is characterized by small size, simple interface, reliable data storage, online rewriting, low power consumption and low voltage writing. 2.E ~ 2PROM in I ~ 2C bus color TV In the I ~ 2C bus color TV, E ~ 2PROM memory not only to store the program preselections (including tuning voltage, band, etc.), volume, contrast, brightness, color saturation And some other analog control data, but also to store the accused
