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 51
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
