MicroTouch™ EX II Series Controller

The MicroTouch™ EX II Series Controllers bring flexibility and feature-rich functionality to capacitive and resistive touch screen applications. This high perform ance 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.

Making the Difference-Advanced Capabilities

The EX II series showcases a number of innovative new features. Standard firmware loaded at the factory can be easily replaced in the future with downloadable, newer revisions containing additional functionality. This field upgrade capability means access to the latest 3M Touch Systems firmware features with minimal downtime for upgrades.

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).

The MicroTouch™ SC Series Controllers

The MicroTouch™ SC Series Controllers provide the solution needed for long term viability. This enhanced voltage-driven series supports 3M's full range of resistive touch screens for LCD's, while offering tremendous flexibility and high performance at a cost-effective price. A common board size provides resistive and capacitive designs; a solution that offers standards compliance as well as configuration adaptability.

Making the Difference

3M supports the latest communication interfaces by providing both a Serial (RS232) Plug and Play interface and a Universal Serial Bus (USB) interface compliant with the USB Human Interface Device (HID) class.

In order to provide integration design flexibility for customers, the new SC series of resistive controllers maintain the same form and fit as the newest MicroTouch™ EX II controllers from 3M. Available in a compact 1" x 2" format, and supporting 4-, 5-, and 8-wire resistive touch screens as well as the specialty resistive products, these controllers are designed for easy integration onto LCD panels
