In order to provide reliable and secure touch detection to an even wider variety of automotive displays, Microchip Technology has once again expanded its maXTouch M1 family of touchscreen controllers.
These controllers now span free-form widescreen format displays up to 42 inches down to small, compact screens in the 2 to 5 inch range.
In addition to supporting advanced technologies like Organic Light Emitting Diodes (OLEDs) and microLEDs, the ATMXT3072M1-HC and ATMXT288M1 devices have been designed to function with a broad range of display sizes.
The ATMXT3072M1-HC is Designed For:
- Large, continuous touch sensor designs,
- Covers both the cluster and center information display (CID),
- Addresses the needs of left-hand and right-hand drive vehicles with a single hardware design.
- Help eliminate the need for dedicated hardware designs by the OEM and simplify global automotive market support.
- The continuous touch sensor design maintains uniform optical properties regardless of the ambient lighting environment.
- The host-client ATMXT3072M1-HC solution appears as a single maXTouch device to the host MCU,
- Streamlines system design by removing the need for an external MCU to merge touch coordinates; maXTouch client interaction is managed by the maXTouch host device.
The ATMXT288M1 is Designed For:
- Small screens to meet the increasing demand for compact automotive display solutions,
- Such as traditional analog clocks and AI driver assistants, where physical space constraints are critical,
- A Thin Profile Fine-Pitch Ball Grid Array (TFBGA60) package,
- Delivers a 20 percent reduction in printed circuit board (PCB) area compared to the previous smallest automotive-qualified maXTouch product,
- The ATMXT288M1 is the first TFBGA package introduced in the M1 family,
- Well suited for space-sensitive applications utilizing OLED/microLED technologies.
In comparison to previous generations, the M1 controllers boost the touch Signal-to-Noise Ratio (SNR) by up to 15 dB by utilizing Microchip’s proprietary Smart Mutual touch acquisition scheme and advanced algorithms.
Even with integrated touch sensors exposed to high capacitive loads and substantial display noise coupling, Smart Mutual technology is designed to provide reliable touch detection.
For large, thin displays like on-cell OLEDs, where embedded touch electrodes are exposed to higher capacitive loads and enhanced noise coupling, this capability is especially important because it increases the risk of false or missing touch detections with conventional capacitive methods.
Key Comment
“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,” said Giovanni Fontana, director of Microchip’s human machine interface division. “This expansion of our maXTouch M1 family addresses the complexities of integrating touch into these next-generation displays, offering robust and secure touch detection for a diverse array of formats.”
