Highly Configurable 2.4-inch TFT LCD for Versatile Embedded &
Industrial Applications
Saef Technology Limited introduces the SF-TC240H-8944A-N, a
versatile 2.4-inch TFT LCD module designed for engineers who
require interface flexibility without compromising display
performance. With a 240x320 resolution, the ILI9341 driver, and
support for multiple interface modes—including parallel MPU, SPI,
and RGB—this module is ideal for industrial HMIs, medical devices,
test equipment, consumer electronics, and IoT dashboards.
Engineered for Design Flexibility & Ease of Integration:
Multi-Interface Support: Configure as MPU 8/9/16/18-bit parallel,
SPI, or RGB interface via IM[3:0] pins, allowing seamless
compatibility with a wide range of MCUs and processors.
Bright & Readable Display: 250 cd/m² brightness and 250:1 contrast
ratio ensure clear visibility in various lighting conditions. The
12 o’clock viewing direction is optimized for portrait-mode
applications.
Touch Panel Ready: Includes dedicated pins (YU, XL, YD, XR) for
easy integration of a 4-wire resistive touch panel, simplifying
touch-enabled designs.
Robust & Reliable: Operating temperature range of -20°C to +70°C
and comprehensive reliability testing ensure stable performance in
demanding environments.
Technical Specifications for System Integration:
Active Area: ~36.72mm × 48.96mm
Module Dimensions: 42.72mm × 60.26mm × 2.3mm
Supply Voltage: VCI = 2.6V–3.3V, VDD3 = 1.8V–3.3V
Backlight: 4 white LEDs, Vf = 3.0V–3.4V, If = 80mA total
Interface Signals: Includes TE (tearing effect), DOTCLK,
HSYNC/VSYNC for RGB mode
Compliance: Designed to meet industrial standards with
environmental and reliability testing
