Hi,

Is there any single IC that performs RS232<-->RS485 conversion ?

Thanx

Please do not look at this answer as being sarcastic.

Have you looked at using a PIC or Motorola Nitron for this task?

Having seen the cost of UARTS for this, and they still need a micro anyway, might be best option as both companies supply a protocol stack for this anyway for free

Or you could use a Startech (Exar) UART like the ST16Cxx as they have 2 serial channels that can do 8/9 bit and clocked independent to each other, with or without FIFO

TI/MSC have same ideas.

All need 8 bit interface with Micro Crying or Very sad

You can try this from TI sn65lbc184

also i think a chipt that convert from 232<<>> 485 will be expensive if avilabel

you can try two chip solution like Max232 + TI sn65lbc184
