WEO012864AM est un écran OLED graphique COG de 2,7 pouces avec une résolution de 128x64. Ce module est intégré à l'IC SH1106 ; il peut être communiqué via l'interface I2C, le bus série SPI à 4 fils ou l'interface parallèle 6800, 8080, et son rapport de contraste élevé de 10 000:1 rend l'image de l'écran plus claire. La tension d'alimentation logique est comprise entre 1,65 V et 3,3 V (valeur typique 3V), la tension d'alimentation pour l'écran est comprise entre 6,4V et 13,5V (valeur typique 13V), le devoir de pilotage est de 1/64.
WCe module peut fonctionner à des températures de -40°C à +80°C ; ses températures de stockage vont de -40°C à +85°C. L'écran OLED de 2,7 pouces convient très bien aux applications de domotique, aux équipements haute technologie, aux équipements de mesure, aux systèmes de contrôle industriel, aux instruments médicaux, aux systèmes IoT, etc. La série WEO12864AM propose différentes versions de connecteurs FPC ZIF ; nous proposons actuellement des options de 22 broches, 24 broches, 30 broches et 31 broches ; si les clients ont besoin d'un FPC personnalisé, n'hésitez pas à nous contacter.

| 15 | /CS | This pad is the chip select input. When /CD = “L”, then the chip select becomes active, and data/command I/O is enabled. | |||||||||||||||
| 16 | /RES | This is a reset signal input pad. When /RES is set to “L”, the settings are initialized. The reset operation is performed by the /RES signal level. | |||||||||||||||
| 17 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. A0 = “H”: the inputs at D0 to D7 are treated as display data. A0 = “L”: the inputs at D0 to D7 are transferred to the command registers. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |
|||||||||||||||
| 18 | /WR (R/W) |
This is a MPU interface input pad. When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU /WR signal. The signals on the data bus are latched at the rising edge of the /WR signal. When connected to a 6800 Series MPU: This is the read/write control signal input terminal. When R/W= “H”: Read. When R/W= “L”: Write. |
|||||||||||||||
| 19 | E/RD | This is a MPU interface input pad. When connected to an 8080 series MPU, it is active LOW. This pad is connected to the /RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”. When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU. When /RD = “H”: Enable. When /RD = “L”: Disable. |
|||||||||||||||
| 20~27 | D0~D7 | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance. When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance. |
|||||||||||||||
| 28 | IREF | This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA. | |||||||||||||||
| 29 | VCOMH | This is a pad for the voltage output high level for common signals. A capacitor should be connected between this pad and VSS. |
|||||||||||||||
| 30 | VPP | OLED panel power supply. It could be supplied externally. A capacitor should be connected between this pad and VSS. |
