MEMORY ORGANIZATION
PROGRAM MEMORY Up to 16 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 M87C51FB 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 of microcontrollers the M87C51FB 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 M87C51FB is an enhanced version of the M87C51 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
