MEMORY ORGANIZATION

PROGRAM MEMORY: Up to 8 Kbytes of the program memory can reside in the on-chip ROM. 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 80C51FA/83C51FA is a single-chip control oriented microcontroller which is fabricated on Intel's

CHMOS III (83C51FA) ROM technology. For the remainder of this datasheet references to the ROMless

(80C51FA) and ROM (83C51FA) versions will be denoted as 83C51FA. Being a member of the MCS

microcontroller family, the 83C51FA uses the same powerful instruction set, has the same architecture, and is

pin-for-pin compatible with the existing MCS 51 microcontroller products. The 83C51FA is an enhanced

version of the 87C51. It's 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 brake and

traction control. It also has a more versatile serial channel that facilitates multi-processor communications.
