Overview

The CYAT81688-100AS77 is an automotive-grade capacitive touchscreen controller based on a 48 MHz Arm Cortex core. Designed for harsh environments, it features AEC-Q100 qualification and Infineon's AutoArmor technology to ensure high signal-to-noise ratios and robust electromagnetic immunity.

Why Choose This Part

This controller offers an effective 20-V drive for superior noise suppression and the ability to track fingers through gloves up to 5-mm thick. It features a dedicated low-power wakeup button consuming less than 50 uA and integrated self-test capabilities for safety-critical touchscreen sensors.

Applications

Automotive Infotainment
Main head unit displays requiring multi-touch support for up to ten fingers and glove operation.
Industrial Human-Machine Interfaces
Control panels in wet or noisy environments where water rejection and fingernail tracking are critical.
Off-Road Vehicle Dashboards
Ruggedized displays that must operate reliably between -40C and 105C with thick protective overlays.
