6.5 Passive/Active LCD Panel Support
The S1D13706 directly supports:
• 4/8-bit single monochrome passive panels.
• 4/8/16-bit single color passive panels.
• 9/12/18-bit TFT active matrix panels.
• 18-bit Sharp HR-TFT panels.
• 18-bit Epson D-TFD panels.
All the necessary signals are provided on the 40-pin LCD connector, H1, and 16-pin
Extended LCD Connector, H2. For connection information, see Section 5, "LCD Interface
Pin Mapping" on page 14.
The S5U13706P00C100 does not provide a power supply for the LCD bias voltage needed
by passive LCD panels. An external power supply is required to provide the bias LCD
voltage to the LCD panel.
6.5.1 Buffered LCD Connector
The buffered LCD connector (H1) provides the same LCD panel signals as those directly
from S1D13706, but with voltage-adapting buffers selectable to 3.3V or 5.0V. Pin 32 on
this connector provides a voltage level of 3.3V or 5.0V to the LCD panel logic (see "JP6 -
LCD Panel Voltage" on page 10 for information on setting the panel voltage).
6.5.2 Extended LCD Connector
The S1D13706 directly supports Sharp 18-bit HR-TFT and Epson 18-bit D-TFD panels.
The extended LCD connector (H2) provides the extra signals required to support these
panels. The signals on this connector are also buffered from the S1D13706 and adjustable
to 3.3V or 5.0V (see "JP6 - LCD Panel Voltage" on page 10 for details on setting the panel
voltage).
6.6 External oscillator support for CLKI and CLKI2
The S1D13706 uses CLKI and CLKI2 signals provided by two +5V oscillators. The oscil-
lators are mounted on the evaluation board in 14-pin DIP sockets. The 5V clock signals are
shifted to 3.3V which is accepted by the S1D13706.
