In order to keep this display in production over the long term, we are revising it to the CFAG4265A0-TFK. Any backorders placed now will be fulfilled with the new part when it becomes available. Please contact sales with any questions.

42x65 Dark On Light Gray Graphic LCD

Part Number: CFAO4265A-TFK

42x65 Graphic LCD - Dark On Light Gray

We designed this 42x65 graphic LCD display module so it fits on the face of 1-inch wide devices such as blade servers, disk drive carriers, and expansion cards. The 0.88-inch (22.40 mm) width leaves room for the metalwork and mechanical clearance. This economical COG (Chip-On-Glass) FSTN transflective display is suitable for typical office lighting and is easy to see in dimly lit areas.

Key Features

  • 42 pixels by 65 pixels.
  • 12 o'clock viewing direction can be used in portrait or landscape mode.
  • SPI interface (4-wire Serial Peripheral Interface).
  • Sitronix ST7565R or compatible controller.
  • The FFC/FPC flexible tail is easy to connect with any standard 20 pin 0.5mm pitch ZIF connector.
  • Show off your creativity by tiling multiple displays on 1-inch centers.
  • An additional color choice in the CFAO4265A series is the CFAO4265A-TTL, which has white pixels on a dark background

This display uses three long-life white LEDs for its backlight. The forward voltage is 9.6v to 10.8v. For long life, we recommend driving the backlight at 12mA. The best way to drive the backlight is to use constant current supply. Typically a switching supply designed to control current works well. For details, see the circuit example using LED driver NCP5007 on page 23 of the CFAO4265A_Series_Data_Sheet_Release_2015-07-07.pdf ,

Streamline Development With Carrier Board

To make prototyping or small production with this display quick and easy, we offer the CFAO4265A-TFK mounted on a carrier board. The carrier board has the current-controlled, switching LED driver, including SPI control of the LED brightness. All external components for panel voltage generation are included.

    Product Update #10909: End-of-Life Notification
    Products Affected: CFAO4265A-TFK, CFAO4265A-TTL, CFAO4265A-TTL-CB
    Date Issued: December 12, 2017
    Summary: End-of-Life Notification
    Description: The parts listed have been assigned to End of Life Status.
    Reason: Critical components have been discontinued by the manufacturer.
    Impact: These parts are not recommended for new designs.
    Recommendation: The CFAO4265A-TFK has been replaced by a new design that will function as a "drop-in" replacement.
    The new part number is CFAG4265A0-TFK and can be found here:

    A new series of development kits are also available:

    Part #: CFAG4265A0-TFK-E1-1
    This is a CFAG4265A0-TFK mounted to a CFA10004 carrier board.

    Part #: CFAG4265A0-TFK-E1-2
    This is a CFAG4265A0-TFK mounted to a CFA10004 carrier board with a Seeeduino 4.2

    The CFAO4265A-TTL and CFAO4265A-TTL-CB do not have replacements.

    Availability: The new parts are available now. The CFAO4265A-TTL and CFAO4265A-TTL-CB will be available until current stocks are depleted.
