MEMORY ORGANIZATION
PROGRAM MEMORY Up to 32 Kbytes of the program memory can reside in the on-chip EPROM In addition
the device 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 64 Kbytes of
external data memory
The Intel M87C51FC is a single-chip control-oriented microcontroller which is fabricated on Intel’s reliable
CHMOS III-E technology Being a member of the MCS-51 family the M87C51FC uses the same powerful
instruction set has the same architecture and is pin-for-pin compatible with the existing MCS-51 family of
products The M87C51FC is an enhanced version of the 87C51 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 It also has a more versatile serial channel that facilitates multi-
processor communications
