1 GENERAL DESCRIPTION
The Nuvoton touch key series, NT1160, provides an easy-to-implement touch key interface solution
and supports configurable 16 touch button applications, 3-channel LED output, and multi-key input
mode configuration, such as single touch key, multi-keys and Toggle function to enable the shortest
development cycle. Through the I2C bus implemented by an external device, the NT1160 can be
controlled to handle chip performance precisely.
There is nearly no special requirement for application board circuit design, and no need to design
special ground net or other protections for the key pad. The NT1160 provides excellent anti-static
capability and immunity to EFT. It also supports outstanding immunity to EMI from mobile phone or
walkie-talkie applications. That is to say, the NT1160 provides a comprehensive response to a
variety of applications.
The NT1160 is suitable for a wide range of applications, such as audio panel, telephone keyboard,
instrument control panel, washer control panel, access control system control panel, household
appliances and various small appliances (cooker, disinfection cabinet, microwave, etc.). Almost all
applications related to the control panel key operation can be used.

4 CAPACITIVE TOUCH KEY
4.1 Input Circuit
Each capacitive touch key needs to be connected with one resistor as shown in Figure 4-1. It is
strongly recommended that the resistor value is 390 and the capacitor value is 4.7pF. At the
same time, all the resistors need to be kept as close to sensor pad as possible during PCB layout.

Figure 4-1 Touch Key Reference Circuit
There are two touch key driving signals (CPn) for NT1160 to operate matrix scan. One SIN pin can
distinguish two touch keys through the driving signal as shown in Figure 4-2.
