SDRAM 的原理和时序
- 、 数据输出(读) 在选定列地址后,就已经确定了具体的存储单元,剩下的事情就是数据通过数据 I/O通道 (DQ)输出到内存总线上了。但是在 CAS 发出之后,仍要经过一定的时间才能有数据输出, 从 CAS与读取命令发出到第一笔数据输出的这段时间,被定义为 CL(CAS Latency,CAS潜 伏期)。由于 CL只在读取时出现,所以 CL又被称为读取潜伏期(RL,Read Latency)。CL 的单位与 tRCD一样,为时钟周期数,具体耗时由时钟频率决定。

DS18B20
- 它的功能是: 1.读出当前温度值。 2.可通过按键调整报警温度上下限。按第一个键,进入温度上线调节模式,第二个键温度加,第三个键温度减,再按一下第一个键,进入温度下线调节模式,第二个键温度加,第三个键温度键,再按一下第一个键,正常显示当前温度。 3.当进入报警温度上下限调节时,红灯亮,当显示当前温度是,绿灯亮。 4.当当前温度超过上限温度时,或者低于下限温度时,蜂鸣器报警且黄灯闪烁。 需要说明的是, 一般情况下,DQ引脚应该有一个上拉电阻来拉高电平,但是我通过观察发现,初
