320x240 3.5" Touch Screen Color TFT

Part Number: CFAF320240F-035T-TS

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).
    • 16-bit or 18-bit "DOTCLK" RGB.
    • 3- or 4-wire SPI.
  • Thanks to the built-in Solomon Systech SSD2119 or compatible driver, only a single 3.3v supply is needed for both power and logic.
  • Built-in DC-DC converter for panel voltage.
  • The display module' s 50-pin FFC mates with standard 0.5 mm ZIF sockets such as HFJ150CT-ND and HFK150CT-ND available from Digi-Key.
  • The touch screen FFC/FPC (Flat Flexible Cable / Flexible Printed Circuit) mates with standard 4-position,1.00 mm pitch ZIF (Zero Insertion Force) connectors such as WM3749CT-ND (top contacts) or WM7937CT-ND (bottom contacts), which are available from Digi-Key.
  • 6:00 o'clock viewing angle (polarizer viewing direction) can be used in portrait or landscape orientation.
  • Temperature operation is from -20°C to +70°C.
  • To get you started, free downloadable sample code is under the DATASHEETS & FILES tab below.
  • This TFT and the optional carrier board are RoHS compliant.
  • Crystalfontz America, Incorporated is ISO 9001:2008 certified.

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 55 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.
