4 Technical Description
4.1 Power
4.1.1 Power Requirements
The S5U13L03P00C100 Evaluation Board requires an external regulated power supply
(3.3V / 0.5A). The power is supplied to the evaluation board through pin 34 of the H1
header, or pin 5 of the P2 header.
The green LED ‘3.3V Power’ is turned on when 3.3V power is applied to the board.
Note
H1 connector is not mounted. There is an allocated area for mounting.
4.1.2 Voltage Regulators
The S5U13L03P00C100 Evaluation Board has an on-board linear regulator to provide the
1.5V power required by the S1D13L03 Simple LCD Controller. It also has a step-up
switching voltage regulator to generate adjustable 12~38V, which can be used to power the
LED backlight on some LCD panels.
4.1.3 S1D13L03 Power
The S1D13L03 Simple LCD Controler requires 1.5V and 1.65~3.6V power supplies.
1.5V power for COREVDD and PLLVDD is provided by an on-board linear voltage
regulator.
IOVDD range of S1D13L03 isin the range of 1.65~3.6V. However, IOVDD of the
S5U13L03 P00C100 Evaluation Board can range from 3.0V to 3.6V. When JP4 is set to the
2-3 position, IOVDD is connected to 3.3V. If a different voltage is required for IOVDD,
set JP4 to the 1-2 position and connect the external power supply to pin 32 of connector H1.
Note
HI connector is not mounted. It is only land.
PIOVDD of S1D13L03 is the power used by the LCD interface and can be in the range of
1.65~3.6V. However, PIOVDD of the S5U13L03P00C100 Evaluation Board can range
from 3.0V to 3.6V. When JP6 is set to the 2-3 position, PIOVDD is connected to 3.3V. If
a different voltage is needed for PIOVDD because of the LCD panel requirements, set JP6
to the 1-2 position and connect the external power supply to pin 8 of connector H4.
Note
H4 connector is not mounted. There is an allocated area for mounting.
