ADVANCED INFORMATION
MX10FMAXDQC
SINGLE-CHIP 8-BIT MICROCONTROLLER
• Code protection
• Two priority levels
• Power saving Idle and power down modes
• 64 K external program memory space
• 64 K external data memory space
• Four 8-bit I/O ports
• Full-duplex enhanced UART compatible with the stan-
dard 80C51 and the 80C52
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.
