    Hi to all,

    I have seen on ST brochure an abbreviation ''SCI'' on ST72264G micro.

    Can I use it like a UART comunication with PC (through MAX232) ?

    Tanks in advantage!!

    Hi MBKS,

    I use SCI on the ST72334 and it's easily done with 8bits (7bits+parity). Didn't examine with 8bits+parity but I think it runs as well, certainly a little bit more complicated. The SCI has at least the same features as a good UART.

    If you use the MAX232 you should have no restrictions on communicating on any asynchronous serial communications interface you want, even full-duplex.

    Regards WoRo

    Hi,

    I'm using SCI in the 8+1 bit 38900 baud mode, full-duplex. Works very fine.

    I've also used it at 9600 bauds without problem.

    As already said you just need a MAX232 or similar part, and the transmission is done without RS232 control signals, only Tx and Rx.

    There is an AN about the SCI usage.
