To improve user experience, this sharp looking 3.5-inch diagonal full-color QVGA 320x240 TFT has a 4-wire resistive touchscreen. The 50-pin Flat Flexible Cable (FFC) mates with standard 0.5 mm ZIF sockets.
For quick prototype development, this display is available in a kit with a Crystalfontz breakout/carrier board.(See Under ADDITIONAL OPTIONS below.)
For this same TFT without a touch screen, see the CFAF320240F-035T display module.
Highlights
Active Area is 3.5" diagonal, 70.08 (W) x 52.56 (H) mm (2.76" (W) x 2.07" (H)).
Choose from several interface modes to host:
8-bit, 9-bit, 16-bit, and 18-bit parallel (8080 or 6800).
Part Change Notice #11027: The glass used in the parts list has been changed
Products Affected:
CFAF320240F-035T, CFAF320240F-035T-TS
Date Issued:
December 11, 2018
Summary:
The glass used in the parts list has been changed
Reason:
The change was made to improve performance and function.
Impact:
Customers should not have to make any modifications.
Recommendation:
Although tests at Crystalfontz have not found any difference in code requirements, it is recommended that customers perform their own tests to verify operation with their hardware.
Availability:
The updated displays are available now.

Part Change Notice #10423: BOM change for LED backlight effective 2012/05/29
The LEDs used in the backlight for the CFAF320240F-035 family of TFT LCD modules and any assemblies using the CFAF320240F-035 family of TFT LCD modules produced from 2011-03 to 2011-11 is no longer available. To avoid any interruption in supply for our customers, we have gone back to using the LEDs which were in the backlight assembly prior to that point. The LEDs now used are more toward the blue end of the spectrum, whereas the LEDs used for the March-November 2011 period were toward the red end of the spectrum. There may be a difference in light output, but still in the specified range from our datasheet.
Reason:
Component end of life.
Impact:
Low. The specifications for the LEDs used in the backlight still meet the specifications stated in our datasheets.
Availability:
Current stock.
Price Change:
N/A

Part Change Notice #10403: Glass characteristics change requiring single command initialization change for optimal contrast.
Glass characteristics change requiring single command initialization change for optimal contrast.
Description:
PCN for CFAF320240F family of products due to a change in panel vendors.
Reason:
In order to maintain uninterrupted supply of this module, we changed vendors for the LCD panel so that lead times would not be affected.
Impact:
Because of the slightly different characteristics of the panel, a single command in the initialization of the module should be changed so that optimal contrast can be achieved.
No other changes are necessary.
Recommendation:
Change the following registers from:
write_command(0x001E); // Power Control 5
write_data(0x00B7); // Page 53 of SSD2119 datasheet
to
write_command(0x001E); // Power Control 5
write_data(0x00BE); // Page 53 of SSD2119 datasheet
and contrast should be optimal for the display.
Availability:
Immediately for non-touchscreen modules, with a cut-in for the modules with a touchscreen over the next several months.
