STMPE16M31 and STMPE24M31 Touch Key Controllers

STMicroelectronics' 16/24-channel touch key controller with PWM and ratiometric engines

Image of STMicrelectronics' STMPE16M31 & STMPE24M31 Touch Key ControllersSTMicroelectronics' STMPE16M31 and STMPE24M31 touch key controllers expand the existing portfolio of S-Touch™ products. In addition to 16 or 24 capacitive sensing channels, the controllers offer two built-in ratiometric engines for sliders and wheels. Eight independent PWM controllers allow for control of up to 16 LEDs. The I²C interface supports up to 400 kHz communication with the system host, and a very wide dynamic range allows most applications to work without hardware tuning.
