About the ÉlanSC310
Microcontroller Evaluation Board
Congratulations on your decision to design with the ÉlanSC310 microcontroller!
This sophisticated, integrated device is uniquely suited to meet the needs of the
next generation of embedded solutions. From its high integration to PC/AT
compatibility to remarkable power management, the ÉlanSC310 microcontroller
is the ideal device to enable compact, fully functional, low-power designs with a
quick time to market.
The ÉlanSC310 microcontroller evaluation board has been provided as a test and
development platform for ÉlanSC310 microcontroller-based designs. Most of the
possible options and features of the ÉlanSC310 microcontroller can be exercised
on this board. Since there are numerous options available, this board is a much
larger form factor than could be achieved with a dedicated set of features. . This
evaluation board is provided as a reference only and should only be used to
experiment with the design trade-offs of the ÉlanSC310 microcontroller, make
power measurements, and develop operating and application software.
NOTE: Advanced Micro Devices does not assume any responsibility for the
maintenance of this evaluation tool. Changes to the schematics will only be made
if the board is required to go back through a CAD layout.
Refer to the ÉlanSC310 Microcontroller Data Sheet and the ÉlanSC310
Microcontroller Programmer’s Reference Manual for detailed information on the
ÉlanSC310 microcontroller.
