Function
Power Supply for Operation
P This is a voltage supply pin. It must be connected to external source & always be
equal to or higher than VDDIO.
Power Supply for I/O Pin
This pin is a power supply pin of I/O buffer. It should be connected to VDD or
P external source. All I/O signal should have VIH reference to VDDIO. When I/O
signal pins (CPU, PS, D17~D9, control signals…) pull high, they should be
connected to VDDIO.
Ground of Logic Circuit
P This is a ground pin. It also acts as a reference for the logic pins. It must be
connected to external ground.
Power Supply for OEL Panel
P These are the most positive voltage supply pins of the chip. They must be
connected to external source.
Ground of OEL Panel
These are the ground pins for analog circuits. They must be connected to
P external ground.
VSDH: Segment (Data Driver)
VSSH: Common (Scan Driver)
Current Reference for Brightness Adjustment
I/O This is the current reference pin to generate precharge and driving current. A
68KΩ resistor should be connected between this pin and VSS.
Fine Adjustment for Oscillation
I The frequency is controlled by external 5.1kΩ resistor between OSCA1 and OSCA2.
O ^{The oscillator signal is used for system clock generation.}
When the external clock mode is selected, OSCA1 is used external clock input.
O
Vertical Synchronization Triggering Signal
While using MCU interface, it must be floating.
I
Vertical Synchronization Input
While using MCU interface, it must be connected to VDD.
I
Horizontal Synchronization Input
While using MCU interface, it must be connected to VDD.
I
Dot Clock Input
While using MCU interface, it must be connected to VDD.
I
Video Enable Input
While using MCU interface, it must be connected to VDD.
Select the CPU Type
I Low: 80XX-Series MCU
High: 68XX-Series MCU.
Select Parallel/Serial Interface Type
I Low: Serial Interface
High: Parallel Interface
Power Reset for Controller and Driver
I This pin is reset signal input. When the pin is low, initialization of the chip is
executed. Keep this pin pull high during normal operation.
Chip Select
I Low: SEPS525 is selected and can be accessed.
High: SEPS525 is not selected and cannot be accessed.
Data/Command Control
I Low: Command
High: Parameter/Data
