MEMORY ORGANIZATION
PROGRAM MEMORY Up to 8 Kbytes of the program memory can reside in the 87C51FA On-Chip EPROM
Up to 16 Kbytes of the program memory can reside in the 87C51FB on-chip EPROM Up to 32 Kbytes of the
program memory can reside in the 87C51FC 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 87C51FA 87C51FB 87C51FC is a single-chip control-oriented microcontroller which is fabricated on
Intel’s reliable CHMOS EPROM technology Being a member of the MCS-51 family the 87C51FB 87C51FC
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 87C51FA is an enhanced version of the 87C51 The 87C51FB is an
enhanced version of the 87C51FA The 87C51FC is an enhanced version of the 87C51FB With 8 Kbytes of
program memory in the 87C51FA and 16 Kbytes of program memory in the 87C51FB and 32 Kbytes of
program memory in the 87C51FC it is an even more powerful microcontroller for applications that require
Pulse Width Modulation High Speed I O and up down counting capabilities such as brake and traction
control
For the remainder of this document the 87F51FA 87C51FB and 87C51FC will be referred to as the
87C51FA FB FC
