DieTemp模块数据的电压在做什么？

我已经让开发团队知道了。

在PSoC 4中，芯片温度传感器仅连接到SAR的正输入端。如果你将它发送到其他目的地，那么它将消耗SAR的正输入的路由，使得SAR无法使用。模具温度传感器设计的驱动强度连接到SAR，而不是其他目的地。这意味着它只能与SAR一起使用。您可以将模具温度挂钩到注入通道或其他SAR ADC通道之一。
正如数据表所描述的，SAR应该被配置为测量0到1.024V之间的单端电压，作为未签名的12位值。然后，使用模具TEMP组件提供的API采用表示0至1.024V之间的电压的无符号12位值，并将其转换为温度。电压-温度关系是非线性的。为了近似该曲线，转换函数使用分段（2片）线性方程。这个方程的系数是专门针对每个单独的设备进行修剪的。该算法根据设备的特性来读取作为制造过程的一部分写入的位置的修剪数据。我们不描述这个计算的细节，但是计算的源代码作为组件的一部分被提供。如果您想了解转换的确切细节，则构建包含模具TEMP组件的设计并查看生成的CurtToSkyCelsiSUs（）函数。

   In PSoC 4 the die temp sensor is only connected to the positive input of the SAR.  If you were to send it to some other destination, then it would consume the routing for the positive input of the SAR making the SAR otherwise unusable. The die temp sensor was designed with the drive strength to connect to the SAR and not to other destinations. This means that it can only be used in conjunction with the SAR. You can hook the die temp up to the injection channel or to one of the other SAR ADC channels.  
    As the datasheet describes the SAR should be configured to measure a single ended voltage between 0 and 1.024V as an unsigned 12 bit value.  The API provided with the Die Temp component then takes this unsigned 12 bit value that represents a voltage between 0 and 1.024V and converts it to temperature.  The Voltage to Temperature relationship is non-linear.  To approximate this curve the conversion function uses a piece wise (2 pieces) linear equation.  The coeffecients for this equation are trimmed specifically for each individual device.  The algorithm reads the trim data from locations that were written as part of the manufacturing process based on the characteristics of the device.  We don't describe the details of this calculation, but the source code of the computation is provided as part of the component.  If you would like to understand the exact details of the conversion, then build a design that includes the Die Temp component and review the CountsTo_Celsius() function that is generated.

Brad，那么你不能在dieTMP上使用比较器。
模块和检测T警报在/下的条件？Eg.佑
使用SAR卡住了吗？
问候，Dana。

  Brad, then you could not use a comparator on the DieTemp
    module and detect a T alarm over/under condition ? Eg. you
    are stuck using SAR ?
