MEMORY ORGANIZATION  
PROGRAM MEMORY: The M80C51FB can address up to 64K of program memory external to the chip.  
DATA MEMORY: This microcontroller has a 256 x 8 on-chip RAM. In addition it can address up to 64K bytes of  
external data memory.  
The Intel M80C51FB is a single-chip control-oriented microcontroller which is fabricated on Intel’s reliable  
CHMOS III-E technology. Being a member of the family of MCS 51 microcontrollers, the M80C51FB uses the  
same powerful instruction set, has the same architecture, and is pin for pin compatible with the existing  
MCS 51 microcontroller family of products. The M80C51FB is an enhanced version of the M80C51. Its added  
features make it an even more powerful microcontroller for applications that require Pulse Width Modulation,  
High Speed I/O, and up/down counting capabilities such as motor control or fin actuation. It also has a more  
versatile serial channel that facilitates multi-processor communications.
