Chapter 4 Technical Description
4.1 Power
4.1.1 Power Requirements
The S5U13L02P00C100 Evaluation Board requires an external regulated power supply (3.3V / 1A). 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 allocated space for the connector.
4.1.2 Voltage Regulators
The S5U13L02P00C100 Evaluation Board has an on-board linear regulator to provide the 1.5V power required by
the S1D13L02 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 S1D13L02 Power
The S1D13L02 LCD controllerrequires 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.
HIOVDD range of S1D13L02 isfrom 1.65V to 3.6V. However, HIOVDD of the S5U13L02P00C100 Evaluation
Board can range from 3.0V to 3.6V. When JP4 is set to the 2-3 position, HIOVDD is connected to 3.3V. If a different
voltage is required for HIOVDD, set JP4 to the 1-2 position and connect the external power supply to pin 32 of
connector H1.
Note
H1 connector is not mounted. There is allocated space for the connector.
PIOVDD of S1D13L02 is the power used by the LCD interface and GPIO[23:8] and can range from 1.65V to 3.6V.
However, PIOVDD of the S5U13L02P00C100 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 2 of connector H4.
Note
H4 connector is not mounted. There is allocated space for the connector.
GIOVDD of S1D13L02 is the power used by GPIO[7:0] and can range from 1.65V to 3.6V. However, PIOVDD of
the S5U13L02P00C100 Evaluation Board can range from 3.0V to 3.6V. When JP8 is set to the 2-3 position,
GIOVDD is connected to 3.3V. If a different voltage is needed for GIOVDD, set JP8 to the 1-2 position and connect
the external power supply to pin 6 of connector H4.
