Élan SC400 Microcontroller
Evaluation Board
The Élan™SC400 microcontroller evaluation board is a
stand-alone evaluation platform for the ÉlanSC400 and
ÉlanSC410 microcontrollers.
As a test and development platform for designs based
on the ÉlanSC400 and ÉlanSC410 microcontrollers,
this AMD product is used by system designers to ex-
periment with design trade-offs, make power measure-
ments, and develop software. Contact your local AMD
sales office for more information on evaluation board
availability and pricing.

ARCHITECTURAL OVERVIEW
The architectural goals of the ÉlanSC400 and
ÉlanSC410 microcontrollers included a focus on CPU
performance, CPU-to-memory performance, and inter-
nal graphics controller (ÉlanSC400 microcontroller
only) performance. The resulting architecture includes
several distinguishing features of interest to the system
designer:

The main system DRAM is shared between the
CPU and graphics controller, so that the graphics
controller can be serviced quickly to maintain video
display performance at higher panel resolutions.
The internal unified memory architecture (UMA)
implemented on the ÉlanSC400 and ÉlanSC410
microcontrollers means lower cost and less
complication for the system designer, with only one
DRAM interface, fewer pins, and a much smaller
board for many designs.
CPU-to-memory performance is critical for both
DRAM and ROM accesses. The CPU on the
ÉlanSC400 microcontroller has a concurrent path to
the ROM/Flash memory interface and can execute
code out of ROM/Flash memory at the same time
as the graphics controller is accessing DRAM for a
screen refresh. Many system designs can take
advantage of this concurrency without sacrificing
performance.
