1 USB to 3 UART using FT4232H
« on: October 15, 2020, 08:33:40 PM »


Please see the attached image.

I have three devices with only UART in all three devices

I need to communicate with all three devices at the same time or one after the other using one USB

I have see USB to UART using FTDI converter . But that is for one to one.

Here one USB to 3 UART I needs to be connect. Is it possible using FT4232H?

I saw one FTDI device FT4232H and the datasheet says "Single chip USB to four channels UART (RS232, RS422 or RS485) or Bit-Bang interfaces. "

can I use this device for my application ?

Yes the FT4232H can be utilised to provide up to 4 UART connections from a single USB device, each UART connection would present its own COM port to the host machine.
