MicroTouch™ EX II Series Controller

A Sophisticated Electronics Solution
The MicroTouch™ EX II Series Controllers bring flexibility and feature-rich functionality to capacitive and resistive touch screen applications. This high performance electronics platform is based on the innovative MicroTouch™ EX II ASIC, designed to provide higher resolution touch coordinates, on-chip RAM, and a wider operating temperature range. With expanded regulatory approvals, improved power modes, and enhanced ESD and EMI protection, this controller series is a robust solution for popular touch applications.

The EX II series supports both ClearTek™ capacitive and 5-wire resistive touch screens, using the same board size and mounting hole locations. System manufacturers that start with one touch screen technology can move to the other using the same electronic hardware footprint and feature-rich software drivers, simplifying the transition and shortening development cycles. Considered the premium controller for resistive systems, the EX II enables 5-wire resistive touch screens to work in “current-driven” mode, where the X and Y coordinates are calculated with a single measurement, shortening touch response time to 8 ms (typical).
