S5U13A05B00C Rev 1.0 Evaluation Board
Rev. 1.1
6.7.2 Extended LCD Connector
The S1D13A05 directly supports several extended panel types such as the Sharp 18-bit HR-
TFT, Casio TFT and compatible panels. The Extended LCD Connector H2 provides the
extra signals required to support these panels. The signals on this connector are provided
directly from the S1D13A05 without any buffering and are 3.3V signals.
6.7.3 TFT Type 3 Extended LCD Connector
The S1D13A05 directly supports 18-bit TFT Type 3 compatible panels. The TFT Type 3
Extended LCD Connector H3 provides the extra signals required to support panels
compatible with the specified timings. The signals on this connector are provided directly
from the S1D13A05 without any buffering and are 3.3V signals.
6.8 USB Support
The S1D13A05 USB controller provides a Revision 1.1 compliant USB client. The
S1D13A05 acts as a USB device and connects to an upstream hub or USB host through
connector J1 on the S5U13A05B00C evaluation board. Clamping diodes have been added
to protect the USB bus from ESD and shorting.
6.8.1 USB IRQ Support
The S1D13A05 supports interrupts using the output pin, IRQ. In order to support interrupts
from the USB client of the S1D13A05, the S5U13A05B00C evaluation board connects
IRQ to PCI interrupt INTA# from the PCI slot. The IRQ pin output to the PCI bus can be
disabled by removing jumper JP4.
6.9 External oscillator support for CLKI and CLKI2
The S1D13A05 can use CLKI and CLKI2 sources other than the Clock Synthesizer. Two
+3.3V supplied 14-pin DIP package sized oscillator slots are present on the board.
6.10 External oscillator support for USBCLK
The S1D13A05 can use a 48MHz oscillator for the USBCLK source, instead of the USB
crystal oscillating circuit. A +3.3V supplied 14-pin DIP package sized oscillator slot is
present on the board.
Note
The board supports either an external crystal or an external oscillator for USB function-
ality. Only one can be enabled at a time. If an external crystal is used for the clock
source for the USB module, the USBCLK input needs to be disabled by using a pull-
