P87C52 datasheet



The Intel 8XC52/8XC54/8XC58, P87C52 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 applications 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.
