Overview
This chip is a sensor IC to detect micro capacitances and can be used in touch sensors.
Internally, the chip employs the CMOS process and is contained in a 32-pin TQFP plastic package.
The IC has 8 independent measurement pins, of which each can measure capacitance independently.
On/Off- or serial communication output can be selected as the output mode.
The IC is provided with an EEPROM that can store operation mode.
