Microchip Unveils Advanced Touch Solutions for Automotive Displays
Microchip Enhances Automotive Technology with New Touch Solutions
Microchip Technology, a leader in embedded control and processing solutions, continues to shape the future of automotive displays. Recently, the company has expanded its maXTouch M1 Generation touchscreen controller family to support the demands of modern vehicles. With advancements toward larger, curved, and uniquely shaped displays, these controllers are designed for optimal performance and reliability.
Innovative Touchscreen Technology
As automakers embrace smart cockpit designs, integrating features like Organic Light Emitting Diodes (OLEDs) and microLEDs, challenges arise regarding capacitive touch sensing. Microchip’s new touchscreen controllers, ATMXT3072M1 and ATMXT2496M1, cater to these hurdles by providing robust solutions that facilitate the integration of large, innovative displays up to 20 inches in 16:9 format and 34 inches in 7:1 format.
Tackling the Challenges of Touch Integration
Modern displays equipped with on-cell OLED technology can lead to increased false or missed touch detections due to higher capacitive loads and display noise. By employing Microchip’s proprietary Smart Mutual touch acquisition method, the new maXTouch controllers enhance the touch Signal-to-Noise Ratio (SNR) by up to +15 dB, ensuring accurate touch detection even in difficult conditions.
User Experience and Safety Enhancements
Patrick Johnson, a senior corporate vice president at Microchip, emphasizes the importance of reliable touch functionality in automotive designs. The ability to blend advanced technology with intuitive touch response ensures that drivers enjoy a remarkable user experience. Additionally, features like the Shape Event Trigger and automated pattern Pulse Width Modulation (PWM) allow for a seamless haptic feedback experience, mitigating distractions while driving.
Compliance and Safety Standards
Microchip’s ATMXT3072M1 and ATMXT2496M1 controllers are engineered to comply with ASIL-A and B standards. Developed under the company’s ISO26262 Functional Safety Management System, certified by TÜV Rheinland, these controllers are well-equipped for automotive applications. The built-in security features not only enhance performance but also ensure compliance with ISO 21434:2021 standards, allowing for reliable firmware updates via Over-the-Air (OTA) mechanisms.
Development Tools for Comprehensive Testing
Microchip provides a comprehensive evaluation environment for developers looking to integrate these controllers into their designs. The EV01S50A development printed circuit board (PCB) and the EV13B92A evaluation kit streamline the testing and evaluation processes, offering valuable resources for manufacturers aiming to innovate in the automotive display sector.
