4.7 SD Card Interface
The S1D13719 Mobile Graphics Engine has a SD Card interface. The S5U13719P00C100 evaluation board is
designed with a SD Card socket, J1. Note that J1 socket and related components, R13-R19 and C37-39, are not
populated on the S5U13719P00C100 evaluation board.
The SD Card interface has a general purpose output pin GPIO19/SDGPO, which is used to turn on a LED (D1). Note
that D1 LED and related components, U2, C42 and R21, are not populated on the S5U13719P00C100 evaluation
board.
The following figure shows the location of the SD Card connector (J1) and the SD Card LED (D1).

4.8 GPIO Connections
The S1D13719 Mobile Graphics Engine has 22 GPIO pins. Some GPIOs have multiple functions. The GPIO pins
are routed to the connectors on the S5U13719P00C100 evaluation board. If any pin is configured as a GPIO, it will
be available on the connectors as listed below:
• GPIO[10:0] pins are routed to connector H5.
• GPIO[18:11] pins are routed to connector J1. Note that connector J1 is not populated on the S5U13719P00C100
evaluation board.
• GPIO[19] pin is not routed to any connector on the board. It is routed only to pin 2 of U2 footprint on the board.
Note that U2 is not populated on the S5U13719P00C100 evaluation board.
• GPIO[21:20] pins are routed to connector H6. Note that connector H6 is not populated on the
S5U13719P00C100 evaluation board.
