Microchip Technology said on the 28th that it has expanded its maXTouch M1 touchscreen controller lineup to support a wide range of sizes for in-vehicle displays.
The new products cover a broad lineup from extra-large 42-inch widescreens to ultra-small 2–5 inch displays. In particular, they provide stable touch detection performance optimized for next-generation display technologies such as organic light-emitting diode (OLED) and microLED.
The newly launched M1 controllers apply Microchip's proprietary Smart Mutual touch acquisition technology. Through this, the signal-to-noise ratio (SNR) has been improved by up to 15 decibels (dB) compared with the previous generation. The technology effectively controls high capacitive loads and noise interference that occur in thin display structures such as on-cell OLEDs, preventing touch malfunctions.
By product, the ATMXT3072M1-HC is for large screens where the instrument cluster and the central information display (CID) are consolidated. It supports left-hand and right-hand drive vehicles with a single hardware design, improving design efficiency for manufacturers. It adopts a host-client method recognized as a single chip without an external microcontroller (MCU), reducing system complexity.
The ATMXT288M1 for small screens targets applications with space constraints, such as smart knobs or AI voice assistant screens. By applying an ultra-compact package (TFBGA60), it reduces printed circuit board (PCB) area by about 20% compared with existing products.
Giovanni Fontana, director of Microchip's Human-Machine Interface business unit, said, "With the spread of software-defined vehicles (SDV), requirements for cockpit displays are changing rapidly," adding, "The expansion of the M1 lineup will help manufacturers easily integrate touch technology into various forms of next-generation displays."
Meanwhile, the new products support a range of in-vehicle operating systems (RTOS), including Linux, Android and QNX, and provide design convenience through the maXTouch Studio development environment.
