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.
