Le WEO025664E est un affichage OLED graphique COG de 3,55 pouces avec une matrice de 256x64 points, piloté par le contrôleur SSD1363. Il prend en charge un niveau de gris 4 bits (16 niveaux) et propose plusieurs options d'interface : parallèle 6800/8080, SPI 3 fils/4 fils et I2C. L'ajout de l'I2C offre une flexibilité supplémentaire pour les conceptions nécessitant une communication simplifiée et une consommation d'énergie réduite.
En revanche, le WEO025664D utilise le contrôleur SSD1322 et prend en charge les interfaces 6800/8080 parallèle et SPI, mais ne prend pas en charge l'I2C. Les deux modèles partagent les mêmes dimensions physiques et la même résolution d'affichage, mais le WEO025664E est plus adapté aux applications nécessitant une plus grande polyvalence d'interface.
Les deux modèles offrent un contraste élevé, de larges angles de vue et un cycle de service de 1/64 pour une gestion efficace de l'énergie. Le WEO025664E fonctionne avec une alimentation logique de 3,3 V et une tension de pilote d'affichage de 16 V, avec une consommation typique de courant de 35 mA à un motif de damier à 50 % (VCC = 16 V).
Le WEO025664E est conçu pour un affichage stable et à long terme dans des applications telles que les dispositifs médicaux, les panneaux de contrôle et les systèmes de libre-service. Il fonctionne dans une plage de températures de –40°C à +80°C, avec une plage de température de stockage allant de –40°C à +85°C.

| 6 | D7 | These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. When serial interface mode is selected, D2, D1 should be tied together as the serial data input: SDIN, and D0 will be the serial clock input: SCLK. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL. |

| 14 | E(RD#) | This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH and the chip is selected. When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
|||||||||||||||
| 15 | R/W# (WR#) | This pin is read / write control input pin connecting to the MCU interface. When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW. When 8080 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 chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
