请问谁能给我这个电阻的阻值在PSOC 5开漏输出时提供?

亲爱的开拓者,
谁能给我这个电阻的阻值在PSoC 5开漏输出高阻抗状态时提供。

   dear develpers,
    can anyone give me the value of the resistance offered by an open drain output in PSoC 5 when is in in high impeadance state.

数据表并没有明确地说出那个数字。我能想到的最好的是输入电流输入。对于正常的GPIO,这是2 NA。对于SiO输入,当输入电压大于Vddsio时,其14NA或10μA。从这些数字可以计算电阻(它们用3V输入电压指定)。

  The data sheet does not explicitely tell that number. The best I can come up with is the input current into the inputs. For a normal GPIO, this is 2 nA. For a SIO inputs its 14nA, or 10µA when the input voltage is greater than Vddsio. From these numbers you can calculate the resistance (they are specified with a 3V input voltage).

亲爱的RLI,
什么是SIO输入。请说明它是否与漏极输入相同。

  Dear Rli ,
    What is an SIO input. Please clarify whether it is same as an open drain input

SIO是一种特殊的输入引脚。它允许启用一些特殊特性(例如更高的输出驱动器,能够处理高于电源电压的输入电压)。正常和SIO引脚都可以设置为打开漏极。
也许我建议您阅读PSoC5LP数据表和PoS5LP的体系结构参考手册(TRM),解释了不同PIN类型的所有细节。

     以下为原文
  SIO is a special kind of input pin. It allows for some special features to be enabled (e.g. higher output drive, ability to handle input voltages higher than supply voltage). Both normal and SIO pins can be set to open drain.
    Maybe I suggest you read the PSOC5LP data sheet, and the architecture reference manual (TRM) for the PSoC5LP, there all the details about the different pin types is explained.

亲爱的HLI,
谢谢你的澄清。因此,我可以把高阻抗状态下的电阻值设为3V/10NA。=300兆欧?

   dear hli ,
              Thanks for the clarification. so can I take the resistance in the high impeadance state to be 3V/10nA. = 300 Meg ohms?
