éLAN?SC520 MICROCONTROLLER
The élan?SC520 microcontroller is a full-featured microcontroller developed for the 

general embedded market.
The élanSC520 microcontroller combines a 32-bit, low-voltage Am5x86? CPU with a complete 

set of integrated peripherals suitable for both real-time and PC/AT-compatible embedded 

applications. PURPOSE OF THIS MANUAL This manual includes in reference format the 

complete set of registers required to configure the élanSC520 microcontroller and control 

its peripherals. This manual does not document the Am5x86 processor registers. Intended 

Audience This reference manual is intended primarily for programmers who are developing 

code for the élanSC520 microcontroller. Computer software and hardware architects and 

system engineers who are designing or are considering designing systems based on this 

microcontroller may also be interested in the information contained in this document. For 

more information on programming this microcontroller, see the élan?SC520 Microcontroller 

User’s Manual, order #22004.
