Descrizione

La serie WEN025664A è un display OLED grafico monocromatico COF da 2,8 pollici con una risoluzione di 256x64 pixel. È dotato del circuito integrato SSD1322 e supporta diverse interfacce, tra cui interfacce a 8 bit 6800/8080 e interfacce SPI a 3/4 fili. Le dimensioni del modulo WEN025664A sono di 85,0 × 39,8 mm e l'area attiva è di 69,1 × 17,26 mm.

La serie OLED WEN025664A funziona con un'alimentazione a 3V e un metodo di guida 1/64. Supporta le scale di grigi e vanta un elevato rapporto di contrasto di 10.000:1. Il modulo è in grado di funzionare in temperature comprese tra -40°C e +80°C, con un intervallo di temperatura di stoccaggio da -40°C a +83°C.

Con una cornice metallica con una scheda PCB e quattro fori per viti, il WEN025664A facilita l'installazione per i clienti. La serie OLED, dotata di una scheda PCB, può connettersi facilmente alle applicazioni utilizzando cavi, eliminando la necessità per i clienti di sviluppare ulteriori schede PCB. L'integrazione delle impostazioni dell'interfaccia e dei circuiti VDD migliora la facilità d'uso. Inoltre, i quattro fori per viti sulla PCB semplificano il processo di installazione sul prodotto applicativo.

La serie WEN025664A offre anche un'opzione con lo stesso pannello OLED ma con un pannello touch. Si prega di scegliere la serie WEN025664A-CTP per l'opzione con pannello touch.

SPECIFICHE TECNICHE

Funzione dei Pin di Interfaccia

Pin Number Simbolo I/O Funzione
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.

DB6
DB7
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.
