CY8CKIT-059 PSoC® 5LP Prototyping Kit Guide, Doc. #: 001-96498 Rev. *G

Hardware

4.2.6.4

System Capacitors

The PSoC 5LP Prototyping Kit has seven capacitors, which are used when ADC operation at high

frequencies, CapSense, or external 32-kHz crystal oscillator is required in the application.

■

Four ADC bypass capacitors: Required for proper ADC sampling at high frequencies:

❐

C9 and C12 – For two SAR ADCs

❐

C7 and C13 – For Delta Sigma ADC

■

A CapSense capacitor (CMOD): Required for proper CapSense functionality.

■

Two biasing capacitors: Required for interfacing an external 32-kHz crystal oscillator. These

capacitors are added in the Rev *A version of the PSoC 5LP Prototyping Kit.

Note: The crystal oscillator is not placed on the board, it can be soldered on pins P15_2 and P15_3.
