320x240 3.5" Full Color TFT LCD

Part Number: CFAF320240F-035T

Description

For maximum flexibility, this 3.5-inch diagonal full color QVGA 320x240 TFT has lots of different interfaces: 8-bit/9-bit/16-bit/18-bit parallel (8080 or 6800); 16-bit or 18-bit "DOTCLK" RGB; or 3- or 4-wire SPI. For easy connection to your host, the FFC/FPC tail mates with easy-to-find ZIF sockets.

To save time during prototype development, this TFT display module is available in a kit with a Crystalfontz breakout/carrier board.(See Under ADDITIONAL OPTIONS below.)

For a touchscreen version of this display, we offer the CFAF320240F-035T-TS.

Additional Options

As an option, you can order this TFT pre-assembled onto a breakout/carrier board. The board allows easy prototyping through its 0.1" headers. You can also include the carrier board in your end product to simplify construction and assembly. The carrier board contains a constant-current switching LED driver. The PCB is sized to fit neatly within the outline of the display, with a total weight of 53 grams.

We believe in open source hardware designs for Crystalfontz carrier boards and development kits. Under the Datasheets & Files tab is a downloadable zip file that contains everything you need to manufacture your own carrier boards: Gerber files, PADs source schematic and layout, and full BOM.

Part Change Notice #10423: BOM change for LED backlight effective 2012/05/29

Products Affected: CFAF320240F-035T, CFAF320240F-035T-TS, CFAF320240F-035T-CB, CFAF320240F-035T-TS-CB
Date Issued: June 15, 2012
Summary: BOM change for LED backlight effective 2012/05/29
Description: 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.

Products Affected: CFAF320240F-035T, CFAF320240F-035T-TS, CFAF320240F-035T-CB, CFAF320240F-035T-TS-CB
Date Issued: February 24, 2012
Summary: 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.
Price Change: Pricing is not affected by this change.

Product Update #10335: Change in TFT part numbers

Products Affected: CFAF240320K-T-TS, CFAF176220M-T, CFAF240320E-T, CFAF128160C-T, CFAF240320P-T, CFAF320240F-T, CFAF320240F-T-TS, CFAF240400D-T, CFAF128160C-018T, CFAF176220U-020T, CFAF240400D-030T, CFAF320240F-035T
Date Issued: March 29, 2011
Summary: Change in TFT part numbers
Description: We are changing our TFT part numbers to have them better describe the parts being ordered. The change should be complete for all TFT modules shipping within the next six months.

Part numbers will change as follows:
CFAF128160C-T will change to CFAF128160C-018T
CFAF176220M-T will change to CFAF176220U-020T
CFAF240320E-T will change to CFAF240320H-022T
CFAF240320K-T-TS will change to CFAF240320K-024T-TS
CFAF240320P-T will change to CFAF240320S-032T
CFAF240400D-T will change to CFAF240400D-030T
CFAF320240F-T will change to CFAF320240F-035T
CFAF320240F-T-TS will change to CFAF320240F-035T-TS
Reason: There are many TFT modules with the same logical dimensions (resolution) with considerably different sizes. In order to help ease any confusion, we have decided to add the diagonal dimension to the part number.
Impact: The part number is all that is changing, there are no other changes to the parts, so there should be no significant impact.
Availability: The transition period should be about six months from the date of this bulletin.
