128x64 SPI Graphical LCD
Part Number: CFAG12864U2-TFH
This light, thin, low-power graphic LCD display (CFAG12864U2-TFH) is an LED backlit, 128x64 graphic display module. It's visible in all lighting situations, from darkness, normal office lighting, and up to bright sunlight. Making it an excellent daylight readable LCD solution.
Since this graphic LCD is a transflective, positive-mode display, the backlight may be turned off when there is sufficient ambient light to read the display. Turning the backlight off will further reduce the already low power consumption. This display is well suited for compact hand-held devices, or any application where a lot of display in a very small area is needed.
In addition to the 128x64 monochrome graphic array, there is a row of icons across the top of the display, that can easily be turned on and off.
This LCD display has an integrated controller and voltage generating components mounted on the flexible tail. The tail connects to a standard 18-conductor 0.5mm pitch ZIF (Zero Insertion Force) connector:
- Typical top contact: TE Connectivity 1-1734839-8 (DigiKey P/N A100297TR-ND)
- Typical bottom contact: TE Connectivity 1-1734592-8 (DigiKey P/N A100286TR-ND)
This type of connector is mounted like any normal SMT component during your board's standard reflow cycle. The display can then be connected to the PCB at final assembly without soldering or tools.
This monochrome graphic LCD display is also available in a non-backlit version (CFAG12864U2-NFH)
- Thin and light TAB construction with white LED backlight
- Wide temperature range: -20°C to 70°C (-4°F to 158°F)
- Built-in Sitronix ST7565P controller
- Low power consumption
- Perfect in handheld, battery operated devices
- 4-wire, 8-bit SPI or 8-bit parallel interface
Is this small monochrome lcd display still too big? We have the CFAG12864T2-TFH, which is a similar display, but smaller in physical dimensions.
This display is a direct replacement for the CFAX12864U-TFH and CFAX12864U1-TFH which are no longer in production.

Part Change Notice #11033: The parts listed are being set to End of Life Status
- text_snippet
Product Update #11006: The tape carrier of the LCD controller chip has changed from the previous series of parts. This changes the areas where bends in the assembly are allowed.
Products Affected: CFAG12864U2-NFH, CFAG12864U2-TFH Date Issued: September 13, 2018 Summary: The tape carrier of the LCD controller chip has changed from the previous series of parts. This changes the areas where bends in the assembly are allowed. Reason: The LCD controller chip for the CFAX12864T/CFAX12864U family was discontinued by the chip manufacturer.
Crystalfontz created the CFAG12864T2/CFAG12864U2 family as replacements.
The new LCD controller chip used in the CFAG12864T2/CFAG12864U2 is mechanically different compared to the original controller.
This difference changes the areas where bends in the assembly are allowed.
The bendable area of the tail is marked by 3 green lines. On the old parts, the controller chip was mounted 5.5mm from the third green line. On the new tail, the controller chip is mounted 2.5mm from the third green line.
Impact: For many applications, this change will not affect production. Please ensure that your application does not put undue force on the connection between the flex and the LCD glass. Please ensure that there is not undue bending or force on the flex in the area of the hard, inflexible chip. Recommendation: If your application does not put undue force on the connection or chip, then no change is needed.
