Automotive controller supports OLED and ultra-large screens with superior touch performance

In the ever-evolving automotive industry, users demand a seamless HMI experience for their infotainment application. Customers are looking for large touchscreens with advanced features and are venturing into OLED and Micro OLED as their preference of display. OLED is seen as the future of smart mobility applications, allowing flexible design and free-form shapes. Best customer experience coupled with functional safety standards must go hand in hand to deliver a seamless journey for the end user. To address these challenges, Infineon Technologies AG has introduced the Automotive PSoC Multitouch GEN8XL (IAAT818X), a new generation of touch controllers. Created for OLED and micro-LED displays up to 24", the touch controller delivers performance and frame rates that meet today's demands. It provides a seamless user experience on various touch-based interfaces, such as touchscreens, touchpads, and sliders, while fulfilling the rigorous automotive standards for EMC (EMC IEC 61967), including chip-level emission, conducted emission (IEC 62132), and radiated emission (ISO 11452).

The device is AEC-Q100 qualified, Auto-SPICE level 3, and ASIL-B compliant. It is supplied in two different packages: 128-pin and 100-pin TQFP. The touch controller operates reliably despite water droplets, condensation, or sweat and allows users to perform touch operations with gloves up to 4mm. The touch controller's design provides scalability to accommodate larger screen sizes, with the possibility of supporting screens up to 55" via multi-chip architectures. It also supports advanced add-on features like a rotary dial and built-in haptics.

The company provides a comprehensive support package, including application firmware, design guidance for sensor and FPC, and TTHE tuning, to facilitate seamless integration and production.

The device is expected to go into production in Q4 2025, samples are available now.

The new controller will be showcased at electronica 2024, hall C3, booth 502, from November 12 to 15, 2024.
