Hello

CAN ST7 BE USED FOR A RS232 COMMUNICATION WHEN USING INTERNAL RC OSC. ? IS THERE ANY APPLICATIONS FOR IT? WE NEED BAUD RATE OF 2400. I WOULD LIKE TO ADD THAT THE COMMUNICATION IS BETWEEN PC TO MY DEVICE. Shermantec

Yes, there is an application note available for it i.e. AN1530.This application note calliberates the SCI parameter w.r.t internal RC variation.This AN ia valid for the micros which have SCI inbuilt.

There is an another AN 973 (SCI Software Communication with a PC Using ST72251 16-Bit Timer) in case SCI peripheral is not available. For Lite, internal RC has 1% tolerance, but SCI peripheral is not available.
