Touch Controller Update: DATA MODUL Presents mXT2952TD Controller Board

Munich, 23rd of April 2021

Introducing the mXT2952TD touch controller board, the latest innovation from DATA MODUL. Designed for PCAP touch applications in the medium diagonal segment, this controller board offers features that optimize its use in a variety of environments.

The new controller board supports the latest generation of microchip touch ICs and features a new type of signal acquisition method, the differential mutual sensing, which significantly increases the signal-to-noise ratio (SNR) and enables superb touch behavior, even under difficult environmental conditions.

The high SNR makes applications with thicker gloves and thicker cover lenses possible and is crucial for passing electromagnetic compatibility tests according to standard EN61000-4-6 (immunity to conducted disturbances, induced by radio-frequency fields). Even at noise levels of 10V/m and higher, the mXT2952TD controller board can comply with evaluation criterion A (no impairment of the function during and after the test). An improvement in noise immunity allows for use in noise-sensitive environments such as medical and military.

Thanks to the identical PCB dimensions and USB interface, the new controller board is compatible with the predecessor model mXT2952T2 and can be easily incorporated into existing products. With DATA MODUL’s easyANALYZER tuning tool, individual touch settings can be handled as usual.

The mXT2952TD controller board can also perform regular error analyses of sensor signals and voltage levels in real-time, which can then be forwarded to a host. This enables extended service concepts and provides additional reliability in the field.

“The requirements for PCAP touch modules are diverse and constantly increasing. For this reason, our touch solutions designed for industrial applications are true all-rounders in terms of the provided features and also safety.  Harsh environmental conditions such as dust, dirt, and also saltwater with a salinity of three percent and more do not impair the touch functionality. In addition, all touch solutions based on the new controller board can be individually adapted to the respective customer requirements regardless of their degree of complexity. This enables a high degree of flexibility for all industrial areas,” explains Robert Meier, Product Management Industrial Division at DATA MODUL.
