Automotive Qualified maXTouch MXT2912TD-UW Touchscreen Controller for Supporting LCD and OLED Displays
Microchip has introduced the maXTouch MXT2912TD-UW touchscreen controller, a single chip solution for addressing 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 in automotive applications. The MXT2912TD-UW can detect and track multi-finger touch through thick gloves and other thick materials even in the presence of moisture.
Along with the highest report rate for wide displays, the MXT2912TD-UW is independent of the display solutions it can offer an experience similar to that of a smartphone. To meet the ISO 26262 specification for functional safety in road vehicles, the device includes various safety features such as periodic self-test, touch sensor test, internal Flash and RAM tests, full signal data path integrity checks, and an additional microprocessor (MPU) core testing.
Users can leverage 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 as the support for the touch screen controllers. Software support such a Microchip’s maXTouch Studio development tool and maXTouch Analyzer inspection tool is also available for production line testing.
