Hi Sir 

May we have IC can support as below spec?

  1. Serial Ports RS-232 / RS-485 (Dual mode / Software Selectable RS-232/RS-485 ports)
  2. RS-232è4 pin (TXD/RXD/CTS/RTS)
  3. RS-485èFull Duplex (TXD+/TXD-/RXD+/RXD-)

    Hi Bogey,

    No, we do not have a single device supporting both of these interfaces today. We do have several RS-232 and RS-485 transceiver devices, though, and these can be used together to achieve a software-selectable RS-485/232 interface. For an example implementation, you could reference the following design:

    I would be interested in hearing more about your application if there are any further details you are willing to share.

    Regards,
    Max
