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
