Description

WEO025664A est un module écran OLED graphique en structure COG de 2,08 pouces, avec une résolution de 256×64 pixels. Il est basé sur le contrôleur SSD1362 et prend en charge les interfaces parallèles 6800/8080 8 bits, I2C ainsi que SPI 3 et 4 fils. Il supporte également une échelle de gris 4 bits.

Le module fonctionne avec une tension logique de 3V et un mode de pilotage 1/64 duty. La température de fonctionnement est comprise entre -40°C et +80°C, et la température de stockage entre -40°C et +85°C.

WEO025664A présente une structure COG compacte avec une épaisseur de seulement 1,61 mm, adaptée aux systèmes nécessitant un encombrement réduit et une faible consommation. Les applications typiques incluent les équipements domotiques, les instruments de mesure, les appareils portables et les dispositifs médicaux.

Ce modèle est proposé avec différentes options FPC / pin-out, notamment ZIF FPC et Hotbar, afin de répondre aux besoins d’intégration selon les applications.

Fonction PIN sur l'interface

No.

Symbol

Fonction

VCC

Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.

This pin is the segment pre-charge voltage reference pin.
A capacitor should be connected between this pin and VSS.
No external power supply is allowed to connect to this pin.

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
No external power supply is allowed to connect to this pin.

VDD

Power supply for core logic operation.
VDD can be supplied externally (within the range of 1.65V to 2.6V) or regulated internally from VCI when VCI is >2.6V.
A capacitor should be connected between VDD and VSS under all circumstances.

IREF

This pin is the segment output current reference pin.
When external IREF is used, a resistor should be connected between this pin and VSS to maintain current of around 18.75uA.
When internal IREF is used, this pin should be kept NC.

VSS

Ground pin. It must be connected to external ground.

VSS

Ground pin. It must be connected to external ground.

VCI

Low voltage power supply.
VCI must always be equal to or higher than VDD and VDDIO.

BS0

MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1, BS0 are pin select.

BS[2:0]	Interface
000	4 line SPI
001	3 line SPI
110	8-bit 8080 parallel
100	8-bit 6800 parallel
010	I²C

Note (1) 0 is connected to VSS (2) 1 is connected to VCI

BS1

BS2

This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS is pulled LOW (active LOW).
In I2C mode, this pin must be connected to VSS.

RES

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.

D/C

This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.
When 3-wire serial interface is selected, this pin must be connected to VSS.

R/W

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.

This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable 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.

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, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SID.
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.
