Descripción

La serie WEN025664A es una pantalla OLED gráfica monocromática COF de 2.8 pulgadas con una resolución de 256x64 puntos. Está equipada con el circuito integrado SSD1322 y admite múltiples interfaces, incluyendo interfaces de 8 bits 6800/8080 y interfaces SPI de 3/4 hilos. Las dimensiones del módulo WEN025664A son de 85.0 × 39.8 mm, y el área activa es de 69.1 × 17.26 mm.

La serie OLED WEN025664A funciona con una fuente de alimentación de 3V y un método de conducción de 1/64. Admite escalas de grises y presume de una alta relación de contraste de 10,000:1. El módulo es capaz de funcionar en temperaturas que van desde -40°C hasta +80°C, con un rango de temperatura de almacenamiento de -40°C a +83°C.

Con un marco metálico, una placa de circuito impreso (PCB) y cuatro orificios para tornillos, el WEN025664A facilita la instalación para los clientes. La serie OLED, equipada con una placa de circuito impreso, puede conectarse fácilmente con aplicaciones mediante cables, eliminando la necesidad de que los clientes desarrollen placas de circuito impreso adicionales. La integración de configuraciones de interfaz y circuitos VDD mejora la facilidad de uso. Además, los cuatro orificios para tornillos en la PCB simplifican el proceso de instalación en el producto de aplicación.

La serie WEN025664A también ofrece una opción con el mismo panel OLED pero con un panel táctil. Por favor, elija la serie WEN025664A-CTP para la opción con panel táctil.

ESPECIFICACIONES

Función interfaz Pin

Pin Number Símbolo I/O Función
1 VSS P Ground.
2 VDD P Power Supply for Core Logic Circuit
Power supply pin for core logic operation. A capacitor is required to connect between this pin and VSS
3 N.C. P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
4 D/C# I 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.
5 R/W#
(WR#)
I 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.
6 E/RD# I 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.
7~14 DB0 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, DB1 will be the serial data input SDIN and DB0 will be the serial clock input SCLK.

15 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
16 RES# I 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.
17 CS# I 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.
18 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
19 BS1 I Communicating Protocol Select
These pins are MCU interface selection input. See the following table:
BS[1:0] Bus Interface Selection
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 VDD
20 BS0
21~24 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
