Hi,
I'm looking for a ST7 chip with the maximum Baud rate (SCI) For RS232 communication - So far I saw only 500k - does any one know on any other chip with faster UART ? Thanks2003-11-05 07:30 PM
What i know is Maximum baud rate possible is 38.4 Kbps. Where have you found 500k?

Well....I'm working with the ST72321 and according to the Data Sheet you can reach 500k baud rate in the SCI.

500k is available will the following config @ 8MHz cpu:
TR & RR=1, PR=1 Regards sjo2003-11-06 03:16 AM
Hello
Can i get 1M or even more ? Latino2003-11-06 03:17 AM
I'm afraid as per the datasheet - 500k max for the sci

I've checked - According to the Data Sheet in my hands - using 16MHz osc can give you SCI with a 1M maximum.
Take a look on the Formula: Fcpu Tx = ------ 16 * ETPR*(PR*TR) Fcpu Rx =-------- 16 * ERPR*(PR*RR) So if ERPR=PR=RR = 1 and Fcpu=16Mhz => you can get 1M Baud Rate !!!! BUT !!! I've checked and tried it --- and you can't !!!! the Max is 500K [ This message was edited by: TeaMaker on 06-11-2003 16:54 ]2003-11-06 04:45 AM
Remember the maximum fcpu for the st7 is 8MHz not 16MHz.
