Note: Only 251Sx has different stepping. 251Tx has only one stepping (C Stepping). Intel stopped manufacturing the 251Sx with A Stepping in 1995. 251Sx with B Stepping never went into production. Starting at the end of 1995, Intel only manufactures the 251Sx with C Stepping. There are a couple of ways of identifying the stepping of the MCS 251 microcontroller (251Sx).
