Device applied: ATA2508, DPI7 Family
SAMSUNG GSM Phone SGH-U708E applied with ATA2508 was released to the China market in July 2008.
Haptic feedback function of SGH-U708 makes users feel vibration when they touch the buttons.
Besides the touch function, ATA2508 receives mechanical key input signal through ATA2508’s GPIO. A single I2C port that controls both mechanical buttons and touch buttons allows module design simpler.
