Description
Super popular small oled! This white-on-black OLED is perfect for display panels that have little space and need a high resolution 128x32 graphic display. With a 24.38mm x 7.58mm viewing area, this is one of the smallest OLEDs available.
- Thin form factor! 1.45mm
- Solomon Systech SSD1306 or compatible controller communicates with I2C, 3-wire SPI, or 4-wire SPI
- Only 3.3v
- Easy ZIF connection. The FPC mates with a 12-pin ZIF connector, which can be processed through your normal SMT reflow.
- Typical mating ZIF connectors can be found here: Bottom Contact and Top Contact.
The Solomon Systech SSD1306 controller needs only a single 3.3v supply for power and logic levels for communication, making it a top choice in low power or battery powered applications. The 3 wire / 4 wire SPI or I2C serial interfaces require only 12 lines. Coupled with a ZIF connection (0.50mm pitch), connecting this module to your host device is a simple task.
Do you need a carrier board to speed up your development? We have the CFA10054 OLED carrier board for this display.
This OLED display has the same connector as these other displays: 64x48 Small Graphic OLED and Small 48x64 .71inch OLED Display.

| Products Affected: | CFAL12832D-B, CFAL12832D-CW, CFAL12832D-CY, CFAL12832D-PW, CFAL12832D-PY, CFAL12832D-BY, CFAL12832D-BB |
| Date Issued: | November 1, 2018 |
| Summary: | Part Change Notification |
| Description: | The parts listed are being replaced by new part numbers. |
| Reason: | The glass used in these displays is being replaced by thinner more efficient glass. |
| Impact: | The part numbers listed will be replaced by new part numbers. The operation of the displays will not change. The overall thickness of each of the displays will decrease by 0.05mm. The part number changes are: CFAL12832D-CW - CFAL12832B-0091C-W CFAL12832D-PY - CFAL12832B-0091P-Y CFAL12832D-PW - CFAL12832B-0091P-W CFAL12832D-B - CFAL12832B-0091B-W CFAL12832D-BB - CFAL12832B-0091B-B CFAL12832D-BY - CFAL12832B-0091B-Y |
| Recommendation: | Users are recommended to verify that the change in the thickness dimension will not affect the installation of the displays. |
| Availability: | The new parts will be available when current stock is depleted. |
