Communication Protocols Application

An I2C Communication MUX is used when a designer needs to combine several I2C input signals and forward them into a single output line.

Design Steps

  1. Configure a 1:3 demux with LUTs to share the TX signal from the MCU, sent to external UART ports.
  2. Configure a 3:1 mux with LUTs to receive an RX signal from the external UART ports to the MCU.
  3. Use the I2C to select the input port.
