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.
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).
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.

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The CFAO4265A-TFK has been replaced by a new design that will function as a "drop-in" replacement.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:
https://www.crystalfontz.com/product/cfag4265a0tfk-42x65-graphic-one-inch-lcd
A new series of development kits are also available:

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.
Price Change:
Current prices are shown on our website.
Part Change Notice #10648: Controller change from ST7565P to ST7565R
Improved manufacturability, component availability, and lower cost.
Impact:
This change effects all CFAO4265A parts. Testing has shown functional compatibility between the ST7565P and ST7565R.
There are no physical changes to the display.
Recommendation:
It is recommended to obtain test units prior to implementing new parts in production volumes.
Availability:
Inventory with ST765R controller will be available late Q2 / Early Q3 2015.
Price Change:
Lower manufacturing costs are reflected in lower product pricing.
