11 / 107 page  Multiple Channel Capacitive Touch Sensor and LED Driver Datasheet SMSC CAP1214 11 Revision 1.0 (08-30-10) DATASHEET The pin types are described in Table 1.2, "Pin Types". All pins labeled with (5V) are 5V tolerant. Note: For all 5V tolerant pins that require a pull-up resistor, the voltage difference between VDD and the pull-up voltage must never exceed 3.6V. 23 RESET Soft reset for system - resets all registers to default values DI (5V) Connect to Ground 24 FEEDBACK Sensor press feedback output. DO Leave open 25 N/C Not Connected N/A Connect to Ground 26 CS1 Capacitive Touch Sensor 1 AIO Connect to Ground 27 CS2 Capacitive Touch Sensor 2 AIO Connect to Ground 28 CS3 Capacitive Touch Sensor 3 AIO Connect to Ground 29 CS4 Capacitive Touch Sensor 4 AIO Connect to Ground 30 CS5 Capacitive Touch Sensor 5 AIO Connect to Ground 31 CS6 Capacitive Touch Sensor 6 AIO Connect to Ground 32 CS7 Capacitive Touch Sensor 7 AIO Connect to Ground Bottom Plate GND Power Ground Power n/a Table 1.2 Pin Types PIN TYPE DESCRIPTION AIO Analog Input / Output - this pin is used as an I/O for analog signals. DI Digital Input - this pin is used as a digital input. This pin is 5V tolerant. DIOD Digital Input / Open Drain Output - this pin is used as an digital I/O. When it is used as an output, It is open drain and requires a pull-up resistor. This pin is 5V tolerant. DO Push-pull Digital Output - this pin is used as a digital output and can sink and source current. OD Open Drain Digital Output - this pin is used as a digital output. It is open drain and requires a pull-up resistor. This pin is 5V tolerant. Power This pin is used to supply power or ground to the device.
