Descrizione

Il WEO025664E è un display OLED grafico da 3,55 pollici con matrice a punti 256x64, gestito dal controller SSD1363. Supporta una scala di grigi a 4 bit (16 livelli) e offre diverse opzioni di interfaccia: parallelle 6800/8080, SPI a 3 fili/4 fili e I2C. L'inclusione di I2C offre una maggiore flessibilità per i progetti che richiedono comunicazioni semplificate e ridotto consumo energetico.

In confronto, il WEO025664D utilizza il controller SSD1322 e supporta le interfacce parallele 6800/8080 e SPI, ma non supporta I2C. Entrambi i modelli condividono le stesse dimensioni fisiche e risoluzione dello schermo, ma il WEO025664E è più adatto per applicazioni che richiedono maggiore versatilità nelle interfacce.

Entrambi i modelli offrono un alto contrasto, ampi angoli di visione e un ciclo di lavoro 1/64 per una gestione efficiente dell'energia. Il WEO025664E funziona con una fornitura di logica a 3,3V e una tensione di alimentazione del display di 16V, con un consumo di corrente tipico di 35mA con un pattern a scacchiera al 50% (VCC=16V).

Progettato per applicazioni che richiedono un display stabile a lungo termine, come dispositivi medici, pannelli di controllo e sistemi di self-checkout, il WEO025664E opera in un intervallo di temperatura da –40°C a +80°C, con un intervallo di temperatura di stoccaggio da –40°C a +85°C.

Funzione dei Pin di Interfaccia

Pin Number

Simbolo

Funzione

ESD_GND

ESD Ground pin

VSS

Ground pin. It must be connected to external ground.

VCC

Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
A capacitor should be connected between this pin and VSS.

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.

VLSS

Analog system ground pin. It must be connected to external ground.

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.

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.

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.

BS1

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

	8080	I2C	6800	4-wire SPI
BS1	1	1	0	0
BS2	1	0	1	0

Note:
(1) 0 is connected to VSS
(2) 1 is connected to VDD

BS2

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.

CS#

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).

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.

This pin outputs RAM write synchronization signal. Proper timing between MCU data writing and frame display timing can be achieved to prevent tearing effect.
It should be kept NC if it is not used.

IREF

This pin is the segment output current reference pin.
IREF is supplied externally. A resistor should be connected between this pin and VSS to maintain the current around 10uA.
It should be kept floating when internal IREF is chosen by command setting.

23~24

This is dummy pin. It should be kept NC.

This pin is the segment pre-charge voltage reference pin.
A capacitor can be connected between this pin and VSS to improve visual performance. It can also be float per application.
No external power supply is allowed to connect to this pin.

VDD

Power supply pin for core logic operation. A capacitor should be connected between this pin and VSS.

VSL

This is segment voltage (output low level) reference pin.
This pin has to be connected with resistor and diode to ground (details depends on application).
