A 128 x 64 graphic OLED module with two separate areas of color: yellow for the top 16 pixels, and blue for the bottom 48 pixels. This graphic OLED is super low power, using less than 90 mW with all pixels lit. Displays like this can be used in MP3 players, as secondary screens in mobile phones, placed on the end of a blade or hard drive enclosure -- the sky is the limit.

CFAL12864N Graphic OLEDs Family

  • 128x64 graphic OLED display module
  • Very small form factor
  • 2 color areas on the display
  • Extremely wide viewing angles
  • Very high contrast ratio
  • Built-in SSD1306 Controller
  • 8-bit parallel interface or SPI Interface
  • RoHS Compliant
Because this display technology is quickly evolving, these products may have component or process changes between lots. Slight variations (for example, contrast, color, or intensity) are normal and are often still within the specifications stated in our datasheets. If you need the highest consistency, order and arrange delivery for all your product at the same time so that all displays will be from the same lot.

Part Change Notice #10013

Product Affected: CFAL12864N-A-B1
Date Issued: March 4, 2009
Summary: Datasheet correction
Description: Corrected error in Circuit Example Externally Supplied VPANEL (Pg. 11). Drawing incorrectly showed a direct connection between GND and VLOGIC.
Reason: Suggested creating a short by design from power to ground, resulting in the failure of the display.

For reference only. For design purposes, please use the specifications in the datasheet.

Quick Product Info

This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail mated with a "COG" (chip on glass) display. The TAB connector is soldered directly to corresponding pads on your PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost. The TAB style connection requires no separate connector, so the cost is very low, and the ultra thin profile of the display is maintained.

Because this is quickly evolving, cutting edge technology, there may be fit, form or function variances between manufacturing lots.
