Description

The Intel 8XC51RA/8XC51RB/8XC51RC 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 8XC51RA/8XC51RB/8XC51RC uses the same powerful instruction set, has the same architecture, and is pinfor-pin compatible with the existing MCS 51 family of products. The 8XC51RA/8XC51RB/8XC51RC is an enhanced version of the 8XC52/8XC54/8XC58. The added features make it an even more powerful microcontroller for applications that require 512 bytes of on-chip data RAM and dedicated hardware WatchDog Timer with reset-out features.

Throughout this document 8XC51RX will refer to the 8XC51RA, 8XC51RB and 8XC51RC unless information applies to a specific device.

For a detailed description of 8XC51RA/RB/RC, refer to the 8XC51RA/RB/RC Hardware Description, order number 272668.
