Automotive OEMs gain flexible, high-performance touchscreen solutions for evolving cockpit interfaces, supporting accuracy, uniformity, and immersive user experiences.
Automotive displays are continuing to grow in size and complexity as cockpit interfaces are becoming more immersive and software-defined. OEMs are pushing the boundaries of display size, shape, and technology, creating a need for touchscreen controllers that can deliver reliable, accurate, and secure touch detection across both large widescreens and compact panels.
Microchip has expanded its maXTouch M1 family of touchscreen controllers to cover automotive displays from 2 to 42 inches. The new additions include:
- ATMXT3072M1-HC, designed for large, continuous touch sensor designs such as clusters and center information displays
- ATMXT288M1, tailored for compact screens such as analog clocks and AI driver assistant interfaces.
Both products are engineered to work with OLED and microLED technologies and support precise touch detection even under high capacitive loads and display noise.
The controllers use Microchip’s proprietary Smart Mutual touch acquisition technology and advanced algorithms to boost the touch signal-to-noise ratio, ensuring consistent detection. Large displays benefit from a continuous touch sensor design that maintains uniform optical performance, while the compact M1 employs a thin profile fine-pitch BGA package to save PCB space. Host-client architecture simplifies integration by presenting the touchscreen as a single device to the host MCU, reducing external hardware requirements.
Key features of the controllers include:
- Reliable touch detection across displays from 2 to 42 inches
- Support for OLED and microLED technologies
- Smart Mutual technology for improved signal-to-noise ratio
- Continuous touch sensor design for uniform optical performance in large displays
- Thin Profile Fine-Pitch BGA package for space-constrained panels
- Host-client architecture for simplified system integration
- Compatibility with multiple RTOS platforms via maXTouch IDE and Analyzer
Giovanni Fontana, Director of Microchip’s human machine interface division, says, “Fueled by evolving user expectations and the rise of software-defined vehicles, automotive cockpit displays are rapidly changing, and OEMs are pushing the boundaries in size, shape and technology to deliver more immersive and intuitive user experiences,”
