This product has reached end of life and has been replaced by CFAF240320K1-024T-RT
240x320 2.4" Touch Screen Color TFT
Part Number: CFAF240320K-024T-TS
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 Raydium RM68090 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 #10916: End-of-Life Notice
| Product Affected: | CFAF240320K-024T-TS |
| Date Issued: | December 26, 2017 |
| Summary: | End-of-Life Notice |
| Description: | This part has been assigned to End of Life Status |
| Reason: | Critical components have been discontinued by the manufacturer. |
| Impact: | This part is not recommended for new designs. |
| Recommendation: | We recommend this new display: https://www.crystalfontz.com/product/cfaf240320k1024trt-240x320-rgb-tft-lcd |
| Availability: | Until current stock is depleted |
Product Update #10911: End-of-Life Notification
| Product Affected: | CFAF240320K-024T-TS |
| Date Issued: | December 13, 2017 |
| Summary: | End-of-Life Notification |
| Description: | This part has been assigned to End of Life Status. |
| Reason: | Critical components have been discontinued by the manufacturer. |
| Impact: | This part is not recommended for new designs. |
| Recommendation: | This part will be replaced by a new part. |
| Availability: | CFAF240320K-024 displays will be available until current stock is depleted. The replacement part will be available during the first quarter of 2018. |

Product Update #10435: Controller change for CFAF240320K-024T-TS
| Product Affected: | CFAF240320K-024T-TS |
| Date Issued: | October 19, 2012 |
| Summary: | Controller change for CFAF240320K-024T-TS |
| Description: | The ILI9325C controller is being replaced by the RM68090. |
| Reason: | Supply shortages of the ILI9325C controller threatened to disrupt our ability to fill orders, so we have added the RM68090 as the new controller. |
| 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 RM68090 and this display module. Contact support@crystalfontz.com for more information. |

Product 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.
