CY8CMBR3108-LQXI

Cypress Semicon · Touch Screen Controllers · QFN-16-EP(3x3)

CY8CMBR3108-LQXI from Cypress Semicon, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CS0/PS0 input CapSense button / proximity sensor input that controls GPO0; connect to ground if unused.
2 CS1/PS1 input CapSense button / proximity sensor input that controls GPO1; connect to ground if unused.
3 CMOD passive External modulator capacitor pin; connect a 2.2 nF/5 V/X7R or NPO capacitor.
4 VCC power_out Internal regulator output; connect a 0.1-µF decoupling capacitor if VDD > 1.8 V, or short to VDD if VDD is 1.71 V to 1.89 V.
5 VDDIO power_in Power for the I2C and HI lines; connect to VDD if unused.
6 VDD power_in Power supply input.
7 VSS power_in Ground.
8 CS4/GPO0 bidirectional CapSense button / general purpose output (default GPO0); if unused connect to ground or see Unused GPO Pin Connection.
9 CS5/GPO1 bidirectional CapSense button / general purpose output (default GPO1); if unused connect to ground or see Unused GPO Pin Connection.
10 CS6/GPO2 bidirectional CapSense button / general purpose output (default GPO2); if unused connect to ground or see Unused GPO Pin Connection.
11 CS7/GPO3/SH bidirectional CapSense button / GPO / shield electrode (SPO1 in the register map, default GPO3); see Unused SPO Pin Connection if unused.
12 CS2/GUARD input CapSense button controlling GPO2 / guard sensor; functions as AXRES reset during boot-up so must not be grounded at power-up, connect to VDD if unused.
13 CS3 input CapSense button that controls GPO3; connect to ground if unused.
14 I2C SDA bidirectional I2C data line; pull up if unused.
15 I2C SCL bidirectional I2C clock line; pull up if unused.
16 HI/BUZ output Host interrupt / buzzer output (SPO0 in the register map); supply for buzzer and HI pull-up should equal VDDIO.
17 Center Pad passive Exposed pad; connect to VSS for best mechanical, thermal and electrical performance, otherwise leave floating and not connected to any other signal.
