16 KEYS OR 8 KEYS TOUCH PAD DETECTOR IC
GENERAL DESCRIPTION
    The jc229-BSF TonTouch  TM IC is capacitive sensing design specifically for touch pad controls.
The device built in regulator for touch sensor. Stable sensing method can cover diversity conditions.
Human interfaces control panel links through non-conductive dielectric material. The main application
is focused at replacing of the mechanical switch or button. The ASSP can independently handle the 8
touch pads or up to 16 touch pads.
FEATURES
Operating voltage:2.4V}S.SV
Built-in regulator
Stand-by current
At 3V, and sleep mode slow sampling rate 8Hz:
=>Typical 2.SuA for 16 input keys
=>Typical 2.OuA for 8 input keys
Provides to set 8 direct keys or 16 direct keys by option
Provides to set 8 separate outputs only for 8 direct input keys mode
Has a 2-wires serial output interface, both can use for 8 and 16 direct input keys mode
8 separate outputs can select output driving types by option
(CMOS/OD/OC with active high/low)
2-wires serial interface can select active high or low by option
Offer multi-key or single-key feature by option
Provides two kinds of sampling rate that slow sampling rate 8Hz
and fast sampling rate 64Hz at sleep mode
Have the maximum key-on time about 80sec by pin option
Sensitivity can adjust by the capacitance(1}SOpF) outside
