User I/Os
The board comes with the provision of five user I/Os brought out to jumper J22 . These can be used as
general purpose user I/Os. One of the potential applications is DirectC signaling where these five pins
can be used for JTAG signals (TDI, TDO, TMS, TCK, and TRSTN). Other possible uses are for
interfacing with other boards and debugging.

OLED Display
A 96x16-pixel matrix low power OLED is made available on the board for display (). This low power
device, WHITE OLED, requires 3.3 V and 10 V power supplies. The OLED is interfaced with the
SmartFusion MSS I2C0 port (). The OLED displays sharp gaming images or text.
For example, the SmartFusion RTC current time or time between two events can be displayed on the
OLED. The OLED inputs OLED_BS1, OLED_BS2, and OLED_CSN are tied off and OLED_D/C# is
pulled down as required to work with I
2
C mode.
Note:
The latest revision of SmartFusion Evaluation kit(A2F-EVAL-KIT-2) does not have an OLED component
populated on the board. For more information, see
CN1418A: Addendum A - Designing without OLED
