Called MXT2912TD-UW, it works with display up to 45in with a very wide aspect ratio, and supports LCDs and OLEDs.
“Driven by the ISO 26262 specification for functional safety in road vehicles, MXT2912TD-UW contains a variety of safety related features, simplifying the display module system’s path to functional safety certification,” according to the company. “These include periodic self-test, touch sensor test, internal flash and RAM tests, full signal data path integrity checks and additional microprocessor core testing. The embedded firmware is developed to Automotive SPICE processes.”
Up to 32 touch keys are supported, with screens up to 3mm thick (plastic) and multiple glove (5mm) touches “even in the presence of moisture”, said Microchip.
Communication is via I2C or SPI up to 8MHz, and operation is across -40 to +105°C
It comes in a LQFP176 package.
“The automotive industry is driving innovations in interior design, including the integration of sleek human machine interface concepts,” said Microchip v-p Fanie Duvenhage. “Our single-chip solution offers display makers and automotive Tier 1 suppliers simple and known touch solutions for modern vehicle HMI systems.”
Software support includes Microchip’s maXTouch Studio development tool and maXTouch Analyzer inspection tool for production line testing.
