240x320 Parallel Color TFT
Part Number: CFAF240320K-T-TS
Datasheet
Description
This graphic display module is a 2.4" diagonal, full color TFT. Suitable for embedded applications, it is low-power, uses a white LED backlight, and has an integrated touch panel which has its connection brought out to the main TAB connector for the display.
It has an on-board controller and 3v single voltage for supply and logic (backlight not included), so you can easily use any modern microcontroller to interface with this display. It uses an 8 or 16 bit parallel interface, specified via connections to the display.
This module looks wonderful, displaying all information in living color.
- 240xRGBx320 Full color graphic TFT module
- Built-in ILItek ILI9325C or compatible controller
- 16/8 bit parallel interface
- Wide Temperature Range
- Touch panel included
- RoHS Compliant
- The connector on the CFAF240320K-024T-TS is a flex tail mated with a "COG" (chip on glass) display construction. This style of connector is designed to be soldered directly to corresponding pads on your PCB by using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. There are hot-bar soldering machines made that are designed for prototype, rework or repair work of TAB connections.

Part Change Notice #10345: Controller change for CFAF240320K-024T-TS
| Products Affected: | CFAF240320K-T-TS, CFAF240320K-024T-TS |
| Date Issued: | April 25, 2011 |
| Summary: | Controller change for CFAF240320K-024T-TS |
| Description: | The SPFD5408B-C controller is being replaced by the ILI9325C. |
| Reason: | The SPFD5408B-C has been discontinued by the manufacturer. |
| Impact: | Low. While most customers will not require a change to their initialization to continue to use the display, updated initialization code will improve the performance of the display. |
| Recommendation: | Update initialization code to be more in line with the ILI9325 and this display module. |
| Availability: | New orders, for approximately one year. |
| Price Change: | N/A |
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. |
Production Notes
This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail. The TAB connector is soldered directly to corresponding pads on your PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost. The TAB style connection requires no separate connector, so the cost is very low, and the ultra thin profile of the display is maintained.
