The STM8T143 is a single channel, fully integrated, touch sensing capacitive sensor. It uses a ProxSense™ charge transfer capacitive acquisition method that is capable of near range proximity detection. The STM8T143 offers a state of the art capacitive sensing engine with an embedded sampling capacitor and voltage regulator allowing the overall solution cost to be reduced and improving system immunity in noisy environments. It can target a detection range up to 20 cm thanks to the electrode parasistic capacitance compensation (EPCC) feature. The EPCC automatically compensates ground parasitic capacitance sources (such as ground planes, printed circuit board tacks, and large metal objects) which significantly reduce the proximity detection range.
The application fields or typical functions with proximity features are various and include: on/off switches, replacement/enhancement, home buttons, backlighting feature on proximity for user interfaces, wakeup or control function on proximity, find-in-the-dark for lighting equipment, and companion device for battery saving in portable equipment.
The device has been designed to be used in applications where proximity is required and touch conditions can prevail for an extended period of time which may result in uncompensated drift in conventional capacitive sensors. Therefore, a process called DYCAL is implemented.
The STM8T143 is an ideal alternative, cost-effective, and extremely low power solution to replace conventional infrared optical proximity sensors. Capacitive sensing technology is not sensitive to sunlight or artifical light effects. The STM8T143 offers a much lower consumption (12 μA range versus 100 μA range) and a small form factor (DFN8 2*3*0.65 mm). Lastly, there is no need for a clear opening on the bezel to let light pass through.
The STM8T143 is offered in 8-pin packages and features both touch and proximity sensing outputs.
The STM8T143 touch pad can sense through almost any dielectric and thereby allows the electronics to be contained in a sealed enclosure
