6.1 Touch Controller Characteristics
EETI EXC3132 is a MCU based projected capacitive touch screen controller
designed for commercial and industrial applications. EXC3132 controller supports
high voltage driving signal to achieve high SNR and better wideband interference
susceptibility.
EXC3132 provides different working frequencies to avoid narrow band interference.
With high voltage driving and different working frequencies, EXC3132 provides
excellent interference susceptibility performance. EXC3132 provides an excellent
solution for not only finger operation but also with gloves, thicker glass, etc. applica-
tions.
