    IS THERE ANY APPLICATIONS FOR IT?

    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.
