In order to keep this display in production over the long term, we are revising it to the CFA240320E0-024SC. Any backorders placed now will be fulfilled with the new part when it becomes available. Please contact support@crystalfontz.com with any questions.

2.4" EVE Touchscreen Display

Part Number: CFAF240320A0-024SC-A1-1

Are you looking for a great touch display to act as a human-machine interface for your product? This display module has it all.

The capacitive touchscreen overhangs the LCM making this display look fresh and clean when integrated into a product. The small TFT screen packs a punch. It's sunlight readable, has a high pixel density, and displays vibrant colors. The EVE chip simultaneously handles the display, touch, and audio functionality, lowering the development burden.

This module comprises our 2.4" Full-Color Capacitive Touchscreen TFT attached to an EVE accelerated board. Connect with this module using a simple 30-pin FFC ZIF connection.

Some special features:
  • Graphics accelerating FT811 chip for easy graphics control
  • Capacitive Touch (5 points)
  • Sunlight Readable
  • SPI interface
  • IPS
  • Full color TFT
  • 4 x 2-56 Threaded mounting standoffs for simple mechanical design
  • 30-pin FFC ZIF Connection
EVE Graphics Accelerator Features
  • Support multiple widgets for simplified design implementation
  • Recognize touch tags and track touch movement
  • Enhanced sketch processing
  • Anti-aliasing of primitive displayed objects for higher-quality graphics
  • Graphical effects such as alpha-blending, shadows, transitions, wipes, etc.
  • Programmable interrupt controller provides interrupts to host MCU
  • Support playback of motion-JPEG encoded AVI videos
  • Mono audio channel output with wave playback and built-in sound synthesizer
  • PWM output for display backlight dimming control

Part Change Notice #11100: Board Revision

Products Affected: CFAF240320A0-024SC-A1-1, CFAF240320A0-024SC-A1-2, CFAF240320A0-024SN-A1-1, CFAF240320A0-024SN-A1-2
Date Issued: August 17, 2021
Summary: Board Revision
Description: The board is being revised to support a different NXP processor as the helper processor on the board. This will not affect the functionality of the module and is a drop-in replacement.

Hardware Version Changes: h0v1 to h0v2
Firmware Version: N/A
Reason: Due to the ongoing worldwide component shortage, we are unable to source the current processor until 2023. Instead of having a year-long lead time for our product, we are designing in a readily available processor.
Availability: The new version will be available in Q4 of 2021.

Part Change Notice #11088: Touchscreen Voltage Change

Products Affected: CFAF240320A0-024SC, CFAF240320A0-024SC-A1-1, CFAF240320A0-024SC-A1-2
Date Issued: May 26, 2021
Summary: Touchscreen Voltage Change
Description: This change is to move the resistor on the capacitive touch tail from R2 to R1 so that the typical voltage for the capacitive touch screen is 3.3V as specified in the datasheet instead of 1.8V.
Reason: The capacitive touch screen had a resistor placement that made the typical logic voltage 1.8V instead of 3.3V as specified in the datasheet.
Availability: The display will be shipping with the changes on 2021-05-28.
For reference only. For design purposes, please use the specifications in the datasheet.
