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
Part Change Notice #10648: Controller change from ST7565P to ST7565R
| Products Affected: | CFAO4265A-TFK, CFAO4265A-TTL, CFAO4265A-TFK-CB, CFAO4265A-TTL-CB |
| Date Issued: | March 25, 2015 |
| Summary: | Controller change from ST7565P to ST7565R |
| Description: | As part of our continuous improvement, the controller on the CFAO4265A display modules is changing from the Sitronix ST7565P to the ST7565R. ECO-49. Sitronix ST7565P controller datasheet: https://www.crystalfontz.com/controllers/Sitronix/ST7565P/299 Sitronix ST7565R controller datasheet: https://www.crystalfontz.com/controllers/Sitronix/ST7565R/300 |
| Reason: | 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. |
