Supporting
LCD and OLED displays, Microchip’s latest maXTouch® touchscreen
controller reduces integration complexity and cost for ultrawide touch displays
up to 45 inches
New Delhi, April 26, 2021
— To better meet the need for safe, intuitive
and easy-to-use user interfaces within automotive vehicles, designers are
continuing to consolidate the vehicle’s cluster, center stack and co-driver
displays into very wide screens. Streamlining and simplifying system
development for these ultrawide screens often seen in electric vehicles (EVs), advanced
driver-assistance systems (ADAS) and premium vehicles, Microchip Technology
Inc. (Nasdaq: MCHP) today announced its maXTouch® MXT2912TD-UW touchscreen controller. This is the industry’s first automotive-qualified, single-chip solution
that addresses display sizes up to 45 inches with a very wide aspect ratio, supporting
liquid-crystal display (LCD) and organic light emitting diode (OLED) display technologies.
The MXT2912TD-UW reduces the need for multiple touch
controllers within a vehicle’s human machine interface (HMI) display. This
single-chip touch controller provides the highest report rate for wide displays
and is independent of the display resolution, helping achieve the same user experience
that has become accustomed with the smart phone. Also supported by the exceptional
maXTouch family’s intrinsic Signal-to-Noise Ratio (SNR), the MXT2912TD-UW enables
detection and tracking of multi-finger thick gloves through a wide variety of
overlay materials and thicknesses, even in the presence of moisture.
Driven by the ISO 26262 specification for functional
safety in road vehicles, the MXT2912TD-UW contains a variety of safety related
features, simplifying the display module system’s path to functional safety certification.
These include periodic self-test, touch sensor test, internal flash and RAM
tests, full signal data path integrity checks and additional microprocessor
(MPU) core testing. The embedded firmware is developed to Automotive SPICE®
processes.
“The automotive industry is driving new innovations in
interior design, including the integration of sleek human machine interface
concepts. Microchip enables these revolutionary designs with our new touch
controller, supporting wide aspect ratio touch sensors with our unique and
patented technology,” said Fanie Duvenhage, vice president of Microchip’s human
machine interface business unit. “Our single-chip solution offers display
makers and automotive Tier 1 suppliers simple and known touch solutions for
modern vehicle HMI systems, reducing cost, risk and time to market.”
To support its touchscreen controllers, Microchip also
offers complementary devices such as low-dropout regulators (LDOs), 8-16-and-32-bit
microcontrollers (MCUs), controller area network (CAN) and CAN physical layer (PHY)
controllers and more.
