Lumissil introduces a Family of Industry-Leading Capacitive-Touch Sense Controllers

MILPITAS, Calif., Nov. 17, 2020 (GLOBE NEWSWIRE) -- LUMISSIL MICROSYSTEMS, a Division of ISSI, today announced a new family of capacitive touch sensor controllers consisting of IS31SE5117 & IS31SE5118 which simplify the replacement of mechanical buttons in a variety of applications such as home appliances, IoT devices, instrumentation and control panels and liquid level measurement devices. To enable easy prototyping and rapid implementation into any product the software package comes complete with a standard code and calibration GUI.

“The new family of touch sensor controllers integrate a proprietary sigma delta enhanced dual-slope charge sharing capacitance touch technology with up to 24 bit precision to provide high sensitivity and low noise performance," said Ven Shan, VP of Marketing at Lumissil Microsystems. “Such performance is necessary where users wear gloves or surfaces have thick glass or air gaps as in home appliances. In addition, they consume very low average power and include an auto calibration feature that compensates for temperature and humidity changes and any false touch activation providing a superior value point for our customers.”

Both products are supplied as a turn-key product with a standard code. Applicable for variety of cap-touch sensors interfaces (button, wheel, slider and proximity) and materials (glass, plastics, wood etc.).

The development packages include documentation, evaluation boards and calibration GUIs that include a configuration tool. The calibration GUI enables simple device configuration in one flow for calibrating capacitive touch sensors, configuring GPIO ports and saving configuration directly to a file or target device’s flash, with no programing required. A GPIO can also be configured to output melody using on-chip melody/tone generator. Product debugging support is also available from ISSI’s application engineers.

Key features and benefits

Packaging and Availability

IS31SE5117 is available in 24 pin QFN-24 package and IS31SE5118 in 16 pin TSSOP-16 package. They operate from 2.7V to 5.5V over a temperature range of -40°C to +105°C. Samples can be ordered through Lumissil’s global sales team and worldwide distribution partners.
