Other Parts Discussed in Thread: TRS3232E, TRS3221E, TRS213

Hi team,

My customer is looking for an UART to RS232C conversion IC. Could you advise me about the recommended device?

The customer's requirement for UART and RS232C are below.

[UART]

- Baud rate : 38400bps

- Data : 8bit

- Parity : None

- Stop bit : 1bit

[RS232C]

- Method : Start-stop synchronization(Asynchronous method), half-duplex communication method

- Method: Asynchronous method, half-duplex communication method

- Transmission speed: Selectable from among 9600bps, 19200bps, 38400bps, and 115200bps

- Data length: 8 bits + 1 parity

- Stop bit: 1 bit

- Code used: ASCII 8 bit code

- Error detection method: Vertical (even) parity check

Regards,

Yamaguchi

RS-232 ICs are transceivers only, like TRS3221E, TRS3232E, which take any UART signal. You can use MCU to buffer and convert the UART signal. You can find the related information on e2e, like this one.

Hi Hao-san,

Thank you for the proposal of TRS3221E and TRS3232E. Do we have a device that can support 4 ports each of UART port and RS232C port?

Yamaguchi

Yamaguchi-san,

Do you need 4TX or 4RX? TRS213 (4TX/5RX) could be considered.

BTW, you can go to https://www.ti.com/interface/rs-232/products.html
