GENERAL DESCRIPTION
The single-chip 8-bit microcontroller is manufactured in
MXIC's advanced CMOS process. This device uses the
same powerful instruction set, has the same architec-
ture, and is pin-to-pin compatible with the existing 80C51.
The added features make it an even more powerful
microcontroller for applications that require clock out-
put, and up/down counting capabilities such as motor
control. It also has a more versatile serial channel that
facilitates multi-processor communications.
