Descripción

WEO025664D-CTP es una pantalla OLED gráfica COG de 3,55 pulgadas con panel táctil capacitivo en el módulo, con una resolución de 256x64 puntos. El módulo está equipado con el CI SSD1322, que admite interfaces de 8 bits 6800/8080 y SPI de 3/4 cables. La pantalla admite una escala de grises de 4 bits, con un voltaje lógico de 3V y un ciclo de trabajo de 1/64. Este modelo WEO025664D-CTP también incorpora el CI de pantalla táctil capacitiva FT6336U en el módulo, que admite una interfaz I2C con un punto de detección para la pantalla táctil capacitiva.

Este módulo OLED cuenta con una alta relación de contraste de 10,000:1, lo que permite negros más profundos y vibrantes, así como blancos más brillantes. Esto da como resultado una calidad de imagen mejorada, detalles más nítidos y una legibilidad mejorada.

Este modelo WEO025664D-CTP OLED capacitivo de 3,55 pulgadas es ideal para aplicaciones de hogares inteligentes, dispositivos de tecnología inteligente, sistemas de energía, dispositivos de medición, sistemas de comunicación, instrumentos médicos, etc. Este módulo puede funcionar a temperaturas de -20°C a 70°C; sus temperaturas de almacenamiento oscilan entre -30°C y 80°C.

VSS

Ground.

VCC

Power supply for panel driving voltage.
This is also the most positive power voltage supply pin.

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.

VLSS

Analog system ground pin.

6~13

D7~D0

I/O

Host Data Input/Output Bus
These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus.
When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK.

E/RD#

Read/Write Enable or Read
This pin is MCU interface input.
When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low.
When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low.
When serial mode is selected, this pin must be connected to VSS.

R/W#

Read/Write Select or Write
This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode.
When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low.
When serial mode is selected, this pin must be connected to VSS.

BS0

Communicating Protocol Select
These pins are MCU interface selection input. See the following table:

BS[2:0]	Interface
00	4 line SPI
01	3 line SPI
10	8-bit 8080 parallel
11	8-bit 6800 parallel

Note
(1) 0 is connected to VSS
(2) 1 is connected to VDDIO

BS1

D/C#

Data/Command Control
This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the content at D[7:0] will be interpreted as command.

CS#

Data/Command Control
This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW.

RES#

This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.

This pin is No Connection pins. Nothing should be connected to this pin. This pin should be left open individually.

IREF

Current Reference for Brightness Adjustment
This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 10uA.

N.C.

Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.

VDDIO

Power Supply for I/O Pin
It should be matched with the MCU interface voltage level.

VDD

Power Supply for Core Logic Circuit
Power supply pin for core logic operation. A capacitor is required to connect between this pin and VSS

VCI

Power Supply for Operation
VCI must always be equal to or higher than VDD and VDDIO.

VSL

Voltage Output Low Level for SEG Signal
This is segment voltage reference pin.
When external VSL is not used, this pin should be left open.
When external VSL is used, this pin should connect with resistor and diode to ground.

VLSS

Ground of Analog Circuit
These are the analog ground pins. They should be connected to VSS externally.

VCC

Power Supply for OLED Panel
These are the most positive voltage supply pin of the chip. They must be connected to external source.
