Operating voltage 2.4V ~ 5.5V
Built-in regulator for touch sensor
Built-in low voltage reset(LVR) function
Operating current, @VDD=3V no load
At low power mode typical 5.0uA, At fast mode typical 30uA
@VDD=3V operating voltage :
The response time about 160mS at low power mode, 60mS at fast mode
Sensitivity can adjust by the capacitance（1~50pF）outside for each touch pad
Provides Fast mode and Low Power mode selection by pad option (LPM pin)
Provides 8 direct outputs for 8 direct input keys. And all can selec active high or active low by pad option (SAHL pin)
Provides two kinds of serial output interface
Include 2-wires and I2C-bus slave serial interface that can be selected by pad option (SLSERT pin)
Have the maximum on time 120sec/64sec/16sec/infinite by pad option (MOT1, MOT0 pin)
Provides Single-key and Multi-key functions by pad option (SM pin)
2-wires serial interface can selec active high or low by pad option (SAHL pin)
After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled
Auto calibration for life
The re-calibration period is about 1 sec within 8 sec after power-on. When key has been touched within 8 sec or key has not been touched more than 8 sec after power-on, then the re-calibration period change to 4 sec
Applications
Wide consumer products
Button key replacement
