How do I connect the CSD and CSX capacitors on PSoC 4 S-Series devices?
The following cases require configuring the capacitors on these devices.
Case 0 (CSX MODE):
Because the CSX mode does not have the water-proof functionality, this mode requires configuring only the CintA and CintB capacitors at P4 and P4. Recommended values for CintA and CintB is 470 pF.
Case 1(CSD MODE):
If the project does not require the water-proof functionality, you need to configure the CMOD capacitor at P4,P4,P4. The recommended value is 2.2 nF.
If the project requires the water-proof functionality, you need to use the CTANK capacitor configured at P4,P4,P4. You can choose any of the three pins to configure CMOD and CTANK. The CTANK capacitor can decrease the system noise, but it is not mandatory.
Case 2 (CSD&CSX MODE):
If the project does not require the water-proof functionality, you need to configure CMOD at P4, CintA at P4, and CintB at P4.The recommended value for CMOD is 2.2 nF; for CintA and CintB, the recommended value is 470 pF.
If the project requires the water-proof functionality, you need to add only the shield pin. No pins are available to configure the CTANK capacitor.
