    About pins14 to 16 of CY8CMBR3108

      --- Inquiry background ---

      CY8CMBR3108 does not have a reset terminal.

      For example, I want to turn off the power when malfunctioning due to noise.

      At this time, I want to turn off the power after dropping pins 14 to 16 to low level at the host.

      --------------------------

       

      I want to confirm the output terminal configuration of pins 14 to 16 of CY8CMBR3108.

      I understand that pins 14-16 are open drain terminals.

       

      Q1.

      Do these pins not output High in the internal settings?

       

      *

      I don't think pins 14-16 are open drain and these pins never output high.

      I want to make sure that this is correct.

       

      Best Regards,

          Hi noha_3407421,

           

          1. Pins 14, 15 and 16 are open drain drives low pin therefore it can not be driven high without an external pull up.

          2. Pin 12 can be used as a reset pin during boot up. Make certain that this pin is not grounded during power-up for the device to boot up properly. After boot-up, this I/O functions as indicated by the pin name.

           

          Hope this helps.

           

          Regards,
