Introduction
This document contains a list of frequently asked and anticipated questions (FAAQs)
concerning the STM8T141.
The STM8T141 is a single-channel 8-pin capacitive controller for human touch or nearby
proximity detection (up to a few centimeters). This solution replaces the “on/off” switch and
mechanical buttons of most human interfaces. It also enhances the user experience by
offering new activation and gesture controls.
The STM8T141 offers power consumption below 12 µA and simultaneously reports the
detection with a fast response time which is ideal for power critical and battery supplied
applications.
It brings new horizons and new application domains for designing the next generation of
"hand held" devices, including mobile phones, multimedia players, gaming consoles, and
Bluetooth headsets or headphones.
The STM8T141 has a single user configurable output to report the touch or proximity
detection to the host processor.
