The Intel 8XC52 8XC54 8XC58 is a single-chip control-oriented microcontroller which is fabricated on Intel’s
reliable CHMOS III-E technology Being a member of the MCS 51 family of controllers the 8XC52 8XC54
8XC58 uses the same powerful instruction set has the same architecture and is pin-for-pin compatible with
the existing MCS 51 family of products The 8XC52 8XC54 8XC58 is an enhanced version of the
87C51 80C51BH 80C31BH The added features make it an even more powerful microcontroller for applica-
tions that require clock output and up down counting capabilities such as motor control It also has a more
versatile serial channel that facilitates multi-processor communications
