    About the pin processing of unused pin of CY2308ZXI

    NoAr_1540581

      Hello

       

      Q)

      If CLKA3(14pin)  is not used, please tell me pin proccessing of unused pin(CLKA3) as an "EMI" countrmeasure? Is CLKA3(14pin) open? Or is it necessary to add the capacitor? (Other port condition): CLKB1, CLKB2, CLKB3, and CLKB4 are not driven.

       

      In addition, they found the following application note ,it is described that If EMI is a problem, mount a 5pF to 10pF capacitor during testing on page 6.
