128x64 SPI Graphical LCD

Part Number: CFAX12864U1-TFH

Description

This is an extremely low-power 128x64 graphic LCD display module. With its integrated white LED backlight, illuminating the display is no problem in low-light conditions. This display is perfectly suited for hand-held, or any application requiring low power consumption or a very thin display. The top of the display automatically shows a row of icons without your having to render them. This module has an integrated controller and its tail is designed to mate with standard 18-conductor 0.5mm pitch ZIF connectors (typical would be Omron XF2L18351A/ DigiKey P/N OR754CT-ND).

  • Ultra thin and light TAB construction
  • Form, and Function compatible with CFAX12864CP1 series of LCD modules
  • Wide temperature range: -20°C to 70°C (-4°F to 158°F)
  • Built-in Novatek NT7534 controller
  • Great for handheld instruments, cell phones, PDAs, etc
  • Ultra low power consumption
  • Demonstration board available here: DMOX12864U1TFH
  • RoHS Compliant

Product Update #10863: End of Life Announcement with Last Time Buys

Products Affected: CFAX12864U1-TFH, CFAX12864U1-NFH, CFAX12864T1-TFH, CFAX12864T1-NFH
Date Issued: June 26, 2017
Summary: End of Life Announcement with Last Time Buys
Description: The products listed have been assigned to End of Life Status and will be replaced by a new series of displays.
Reason: The controller chip used in these parts will not be available after August 2017. Due to long manufacturing lead times, all orders for last time buys must be received by July 28, 2017.
Impact: These parts will not be available after the last time buy date.
Recommendation: The CFAX12864U1 and CFAX12864T1 series will be replaced by the CFAL12864U2 and CFAL12864LT2 series. The new series is designed to be a "drop-in" replacement.
Availability: The new series will be available for order after July 28, 2017
Price Change: Prices for the replacement modules have not been set yet. Prices will be set by July 28, 2017.
Response: We're offering last time buys until July 28, 2017, and developing a drop-in replacement.

Product Update #10728: CFAX12864U and CFAX12864U1 series backlight improvements.

Products Affected: CFAX12864U1-TFH, CFAX12864U-TFH
Date Issued: July 27, 2016
Summary: CFAX12864U and CFAX12864U1 series backlight improvements.
Description: The white LED backlight of the Crystalfontz CFAX12864U and CFAX12864U1 series of compact graphic display modules is changing as a result of manufacturing improvements of white LEDs and backlight assembly. The changes are as follows:

Forward voltage: Old value 3.5v -> new value 3.5v NO CHANGE
Supply current (typical): Old value 48mA -> new value 40mA 17% decrease
Luminosity (typical): Old value 150 cd/M^2 -> new value 570 cd/M^2 280% increase
Uniformity (typical): Old value 80% -> New value 90% - 12.5% increase

Note: With 16mA of supply current, luminosity is rated at 250 cd/M^2. This is a 66% decrease in current with a 66% increase in luminosity.
Display modules with a date code of 08/01/16 (August 01, 2016) will have the new backlight. Date code prior to 08/01/16 will have current backlight.

To determine the date code, please see the attached document
How to read CFAX12864U and CFAX12864U1 Date Codes.PDF
Reason: As part of our continuous improvement, design changes have been made to the white LED backlight of the CFAX12864U and CFAX12864U1 for improved luminosity, and reduced current profile.
Impact: Reduced current requirements values will effect current driving circuitry.

Increased luminosity values will effect visual appearance.

Recommendation: Test engineering samples when available to evaluate backlight circuitry changes and settings for visual consistency.
Availability: CFAX12864U and CFAX12864U1 display modules with new backlight should begin shipping at the end of Q3 2016.
Engineering samples for testing / validation will be available during this same time frame.
Price Change: No price change is currently scheduled.
