The 8031/8751 microcontroller
The single-chip micro sei dorn appears in hobby ist and amateur elcctronics projects in its true minimum form. The primary reason for this is the difficulty of developing code for the projects without specialist equipment, that is, the high cost of an leE (In Circuit Emulator). Projects based on the 8031 microcontroller appear fairly regularly, but normally the 8031 is configured to run in its expanded memory mode. The amateur may not have encountered these terms before, and a brief description of the 8031 will, therefore, be given together with that of the EPROM version of the processor-the 8731.
