Description
The STMPE1208S is a GPIO 12 channel
capacitive touch key sensor able to interface a
Main Digital ASIC via the two-line bidirectional
bus (I2C). It senses changes in capacitance using
a fully digital architecture, giving fast and accurate
results at very low power consumption. Automatic
Impedance Calibration ensures that changes in
environment will never affect the correct operation
of the capacitive touch keys.
Applications

Notebook Computer, Monitor
■
Set Top Box, Television
■
Portable media player, Game console
■
Mobile phone, Smart phone
■
Home Entertainment Systems
