CY8CMBR3108-LQXIT from Infineon Cypress Semicon, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS0/PS0 | input | CapSense button or proximity sensor input; controls GPO0. |
| 2 | CS1/PS1 | input | CapSense button or proximity sensor input; controls GPO1. |
| 3 | CMOD | passive | External modulating capacitor (connect 2.2 nF, 5 V, X7R or NPO type). |
| 4 | VCC | power_in | Internal regulator output; connect 0.1-µF decoupling capacitor if VDD > 1.8 V, short to VDD if 1.71 V ≤ VDD ≤ 1.89 V. |
| 5 | VDDIO | power_in | Power supply for I2C and HI lines (1.71 V to VDD). |
| 6 | VDD | power_in | Primary power supply (1.8 V to 5.5 V). |
| 7 | VSS | power_in | Ground. |
| 8 | CS4/GPO0 | bidirectional | CapSense button input or General Purpose Output; configurable via I2C. |
| 9 | CS5/GPO1 | bidirectional | CapSense button input or General Purpose Output; configurable via I2C. |
| 10 | CS6/GPO2 | bidirectional | CapSense button input or General Purpose Output; configurable via I2C. |
| 11 | CS7/GPO3/SH | bidirectional | CapSense button, General Purpose Output, or shield electrode (SPO1); configurable via I2C. |
| 12 | CS2/GUARD | input | CapSense button or guard sensor; functions as AXRES during boot-up. |
| 13 | CS3 | input | CapSense button input; controls GPO3. |
| 14 | I2C SDA | bidirectional | I2C serial data line (open-drain); pull-up resistor required. |
| 15 | I2C SCL | bidirectional | I2C serial clock line (open-drain); pull-up resistor required. |
| 16 | HI/BUZ | output | Host interrupt output or buzzer output (SPO0); supply voltage should equal VDDIO. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
