SFTO350PY-7118ACT: A Feature-Rich 3.5-Inch TFT LCD Module with Integrated PCAP Touch for Interactive Embedded Systems

Saef Technology Limited presents the SFTO350PY-7118ACT, a versatile and responsive 3.5-inch TFT LCD module that combines a sharp HVGA (320x480) display with a robust Projected Capacitive (PCAP) touchscreen. Driven by the ILI9488 display controller and the FT6336U touch IC, this module offers unparalleled interface flexibility with support for both MCU parallel (8080-series) and SPI communication. Engineered for reliability across an industrial temperature range (-20°C to +70°C) and featuring a bright 300-nit output, it is the ideal integrated solution for engineers in the USA and Europe developing next-generation HMIs, portable medical devices, smart retail terminals, and IoT control panels where intuitive touch interaction is critical.

Engineered to Address Specific Design Hurdles in Interactive Applications:

• Dual-Interface Flexibility for Optimal Host Compatibility: This module's standout feature is its configurable host interface. Engineers can select the optimal connection for their system: a high-speed 16-bit parallel MCU interface for complex graphical user interfaces (GUIs) driven by application processors, or a pin-saving SPI interface for simpler microcontrollers (MCUs) where GPIOs are at a premium. This eliminates the need for external level shifters or bridge chips, simplifying your BOM and PCB layout.

• Premium Touch Experience with Reliable PCAP Technology: The integrated PCAP touchscreen (FT6336U) supports multi-touch gestures, offers excellent clarity with direct glass bonding, and provides a modern, durable user interface resistant to surface contaminants. The separate touch FPC with dedicated I²C interface (CTP_SDA/SCL) and interrupt pin simplifies software integration and allows for low-power touch sensing.

• Superior Optical Performance for Readability: With a balanced 300-nit brightness and 500:1 contrast ratio, the display ensures clear visibility in most indoor and controlled lighting environments. The 12 o'clock viewing direction is optimized for the most common vertical mounting orientation in handheld and panel-mounted devices.

• Robust Design for Demanding Use-Cases: The module is built to last, undergoing a full suite of environmental reliability tests (thermal cycling, vibration, ESD). The LED backlight system is rated for a typical lifetime of 40,000 hours, ensuring long-term performance in commercial and industrial applications.

• Streamlined Power Architecture: Separate power pins for digital logic (IOVCC: 1.8V) and display analog (VCC: 2.8V) allow for precise power sequencing and management, aiding in overall system power optimization and stability.

Ideal for Creating Engaging User Interfaces in:

• Industrial Human-Machine Interfaces (HMIs): For control panels, factory equipment interfaces, and test stations requiring a responsive, glove-compatible (with thick glove mode) touchscreen and clear display feedback.

• Portable Medical & Diagnostic Devices: Suitable for handheld monitors, patient data entry terminals, and portable scanners where a smooth, cleanable glass surface and reliable touch are essential.

• Smart Home & Building Automation: Perfect for advanced thermostat controls, security system panels, and appliance interfaces demanding an intuitive and modern user experience.

• Retail & Hospitality: For point-of-sale (POS) systems, self-service kiosks, and order terminals where speed and user engagement are key.

Saef Technology: Your Partner for Tailored Interactive Solutions
