Other Parts Discussed in Thread: TRS3227E

Hello.

I’m looking for a very small package RS232 transceiver (3.3V supply, 1Mbps, Enable option). One Rx and one Tx only.

I’m also looking for a UART buffer (buffering between my CPU and an external display unit). 3.3V supply.

Please Advise,

Gilad.

Gilad,

Thank you for your question.

Please consider the TRS3227E RS-232 tranceiver (1Mbps, 3.3V-5V supply range, single channel, with Enable). The datasheet may be found here:

TRS3227E DS

For your UART inquiry, do you have a preference for number of channels, and number of FIFOs?

Best Regards,

Hi Max.

Can you please help with my question regarding the UART "Buffer"?

I want to protect my CPU UART interface from any damage from the external device i'm connected to.

I know its an unusual request to connect UART directley from the CPU to an external device, it is more custom to connect RS232\485 to an external device via transceiver, but this is the requirement.

I need to Drive the UART RX and TX about 500mm fro end to end and also protect my CPU (as mentioned above), using UART interface (1Mbps max).

Any idea?

Gilad.

Gilad,

I apologize for the delay in my response. I have notified Dylan Hubbard in the Logic Forum group to help you with a recommendation for your UART device. He should reply to this thread with his input.

Dear Gilad,

Have you looked into our TVS surge protection devices ?
