Touch ICs scale across automotive display sizes

Two touchscreen controllers join Microchip’s maXTouch M1 family, expanding support for automotive displays over a wider range of form factors. The ATMXT3072M1-HC and ATMXT288M1 cover free-form widescreen displays up to 42 in., as well as compact screens in the 2- to 5-in. range. Both devices are compatible with display technologies such as OLED and microLED.

The AEC-Q100-qualified controllers leverage Smart Mutual acquisition technology to boost SNR by up to 15 dB compared to previous generations. They deliver reliable touch detection even for on-cell OLEDs, where embedded touch electrodes are subjected to high capacitive loads and increased noise coupling.

The ATMXT3072M1-HC targets large, continuous touch sensor designs that span both the cluster and center information display, enabling a single hardware design for left-hand and right-hand drive vehicles. For smaller screens, the ATMXT288M1 is available in a TFBGA60 package, reducing PCB area by 20% compared to the previous smallest automotive-qualified maXTouch product.
