3. Recommended soldering conditions
Temperature conditions for mounting the IC chip
When mounting the IC chip at a high temperature using reflow soldering, the melting temperature of the solder
depends on the mounting board and paste adhesive materials. Referring to the mounting temperature profile shown in
Fig. 1, choose the optimum soldering temperature within the profile.

[Temperature]
Up to three times
(Complete the last reflow under storage condition B in Section 1.)
The surface temperature profile of the device is shown in Fig. 1.

1. 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 20-pin SSOP plastic package.
The IC has 4 independent measurement pins, each of which can measure capacitance independently.
On/off output or serial communication output can be selected as the output form.
The IC is provided with an EEPROM that can store operation mode and other parameters.
2. Pin connections
2.1 Pin arrangement diagram
Note 1: Pins TEST1, and TEST2 are used for testing during manufacture of the IC.
When using these pins, connect them to VDD through a pull-up resistor.
2.2 Pin functions
Pin Desig- Input/
No. nation Output
Function
───
1 OUT2 I/O
SCK
Output pin for measured result
[On/off output mode] channel 2 output (active low)
[Serial communication mode] serial communication clock input
───
2 OUT3 I/O
SD
Output pin for measured result
[On/off output mode] channel 3 output (active low)
[Serial communication mode] serial communication data (duplex)

───
RESET
I
Reset signal input. Inputting low to this pin resets the chip.
Connect this pin to VDD through a pull-up resistor of about 5k . When VDD starts
up, the power-on reset function operates and the chip is initialized.
When the power-on reset function is used, no other reset signal is needed when power
is turned on.
4 TEST1 I
(Connect to VDD through a pull-down resistor.)
5 VSS I
Ground
6 MEAS I
Initiation of measurement. Capacitance measurement is initiated by inputting high to
this pin. While low is input to this pin, the chip is held in standby status.
7,16 VDD I
Supply input (3.0 - 5.5V)
8 TEST2 I
(Connect to VDD through a pull-down resistor.)

───
SETUP
I
Setup mode. Low input to this pin moves the chip into setup mode.
