Description

Thin, very low-power 128x64 graphic LCD display module. This graphic LCD display is visible in most lighting situations, including normal office lighting up to bright sunlight. Since this graphic LCD module has no backlight, there is no power used for the backlight, however, the display is not viewable in dark environments without an external light source. This display is well suited for low-power hand-held devices that are normally used in well-lit environments.

In addition to the 128x64 monochrome graphic array, there is a row of icons across the top of the display.

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 display is available in white LED backlit version (CFAG12864U2-TFH).

  • Thin and light TAB construction
  • Super Wide temperature range: -20°C to 70°C (-4°F to 158°F)
  • Integrated Sitronix ST7565P controller
  • Really Low power consumption
  • Ideal for handheld and/or battery operated devices
  • Easy 4-wire, 8-bit SPI or 8-bit parallel interface

Is this small lcd display still too big? We have the CFAG12864T2-NFH, which is a similar display, only smaller.

This display is a direct replacement for the CFAX12864U-NFH and CFAX12864U1-NFH which are no longer in production.

Part Change Notice #11033: The parts listed are being set to End of Life Status

Products Affected: CFAG12864T2-NFH, CFAG12864T2-TFH, CFAG12864U2-NFH, CFAG12864U2-TFH
Date Issued: January 23, 2019
Summary: The parts listed are being set to End of Life Status
Reason: The controller chip used on these parts is a TAB (Tape-Automated-Bonding) chip. The manufacturer of that chip has discontinued the chip.
Impact: The parts will not be available after Q1 2019. The last time buy is available, but the orders must be placed no later than January 28, 2019.

Recommendation: Drop-in replacements for the parts listed will be available. The replacement parts will use the same controller chip mounted on the glass. The replacements part numbers will be:

CFAG12864U3-TFH
CFAG12864T3-TFH
CFAG12864U3-NFH
CFAG12864T3-NFH

The CFAG12864U3-TFH and CFAG12864U3-NFH will be drop-in replacements. All dimensions and function will not change.

The CFAGF12864T3-TFH and CFAG12864T3-NFH will have the same overall dimensions and function, but the Active area height will decrease by 1.84mm.
Availability: The current parts may not be available after the deadline for the last time buy. The replacement parts should be available by Q2 2019
Response: Customers should take advantage of the last time buy offer to ensure that they will have sufficient stock through Q1 2019.

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.
Availability: N/A
