Açıklama

WEN025664A serisi, çözünürlüğü 256x64 noktaya sahip 2.8 inç monokrom grafik COF OLED ekranıdır. SSD1322 IC ile donatılmış olup, 6800/8080 8-bit ve 3/4-tel SPI arabirimleri de dahil olmak üzere çeşitli arabirimleri destekler. WEN025664A modülünün boyutları 85.0 × 39.8 mm'dir ve aktif alan 69.1 × 17.26 mm'dir.

WEN025664A OLED serisi, 3V güç kaynağında çalışır ve 1/64 duty sürüş yöntemini destekler. Tonlamayı destekler ve 10,000:1 yüksek kontrast oranına sahiptir. Modül, -40°C ila +80°C arasındaki sıcaklıklarda çalışabilir ve -40°C ila +83°C arasında depolama sıcaklık aralığına sahiptir.

Metal bir çerçeve, bir PCB kart ve dört vida deliği içeren WEN025664A, müşteriler için kolay kurulum sağlar. OLED serisi, bir PCB kart ile donatılmış olarak, müşterilerin ek PCB kartları geliştirmelerine gerek kalmadan uygulamalara kolayca bağlanabilir. Arayüz ayarlarının ve VDD devrelerinin entegrasyonu kullanım kolaylığını artırır. Ayrıca, PCB üzerindeki dört vida deliği kurulum işlemini uygulama ürününe kolaylaştırır.

WEN025664A serisi, aynı OLED paneli ancak bir dokunmatik panel ile bir seçenek de sunmaktadır. Lütfen dokunmatik panel seçeneği için WEN025664A-CTP serisini seçin.

AYRINTILAR

Arayüz Pin Fonksiyonlari

Pin Number Sembol I/O Fonksiyon
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.

DB2
DB3
DB4
DB5
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.
