Design Considerations

Complete Temperature Sensing and Control Solution

  • 2-, 3-, 4-wire RTDs
  • RTD 4-wire to 3-wire auto reconfiguration for high reliability
  • All thermocouple types (J, K...)
  • Thermistors
  • Voltage output temperature sensors
  • Diodes used as temperature sensors
  • Digital sensors (I2C, SPI, TMP05)
  • Fan control and voltage output

Increase Integration

  • 8- to 20-bit ADC with PGA
  • ±0.003% signal accuracy (non-linearity)
  • 0.1% internal voltage reference
  • Up to four unique programmable voltage or current sources
  • Supports multiple channels (e.g., ten 4-wire RTD sensors)
  • Control output (i.e. fan or voltage output)
  • Linearization algorithm or lookup table

Reduced Design Time

  • CY8CKIT-025 evaluation board with multiple sensors included to jump-start the design
  • Detailed sensor interface design guidelines in app notes with example projects
  • PSoC Creator’s schematic and component-based approach simplifies solution design



  • CY8CKIT-025 PSoC® 高精度模拟温度传感器扩展板套件 (EBK) 包括 5 个温度传感器和示例项目,旨在使温度感应和控制设计更为快捷、方便。This kit enables the designer to measure temperature accurately to a resolution of 0.1º C.

  • The CY8CKIT-030 PSoC® 3 Development Kit enables you to evaluate, develop and prototype high precision analog, low-power and low-voltage applications powered by Cypress’s CY8C38 high precision analog device family.

  • PSoC Programmer 3.24 or later and KitProg 2.14 or later are required to program the PSoC 4200L device on the PSoC 4 L-Series Pioneer Kit. PSoC Creator installation or the kit installation automatically installs PSoC Programmer and KitProg drivers.


  • PSoC Creator

    PSoC Creator 是最先进的软件开发 IDE,带有创新性的图形设计编辑器,构成独特而强大的硬件/软件协同设计环境。

  • PSoC Designer

    PSoC Designer 是革新的集成设计环境 (IDE),您可以用来自定义 PSoC 以满足您特定的应用需求。PSoC Designer 软件可加快系统的建立和上市进程。
