It handles up to 8 capacitive touch inputs and includes proximity detection, so a finger approaching the surface can wake the system before a button is pressed. The part communicates over I²C, making it a straightforward add-on to any host MCU that has a spare I²C bus. Four integrated LED driver channels provide backlighting for the touch buttons, reducing external component count. ## Lifecycle and sourcing It is ROHS3 compliant. For current pricing and availability, submit an RFQ — we source through independent distribution and confirm both at quote time. No lead-time or stock figures are published here; the quote will reflect real-time supply.","metaTitle":"CY8CMBR3108-LQXIT CapSense Button Controller, 1.8V-5.5V, I²C","metaDescription":"Infineon CY8CMBR3108-LQXIT capacitive touch controller, up to 8 buttons, proximity detection, I²C interface, 16-QFN, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"CapSense® Express™ SmartSense™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Buttons","Series":"CapSense® Express™ SmartSense™","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"16-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"140mA","Number of Inputs":"Up to 8","Voltage - Supply":"1.8V ~ 5.5V","LED Driver Channels":"Up to 4","Proximity Detection":"Yes","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-QFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.80000","currency":"USD"},{"qty":10,"price":"$2.51600","currency":"USD"},{"qty":25,"price":"$2.37360","currency":"USD"},{"qty":100,"price":"$2.02220","currency":"USD"},{"qty":250,"price":"$1.89880","currency":"USD"},{"qty":500,"price":"$1.66144","currency":"USD"},{"qty":1000,"price":"$1.37663","currency":"USD"},{"qty":2500,"price":"$1.28169","currency":"USD"},{"qty":5000,"price":"$1.23422","currency":"USD"}]},"links":{"datasheetUrl":"https://www.infineon.com/dgdl/Infineon-CY8CMBR3002_CY8CMBR3102_CY8CMBR3106S_CY8CMBR3108_CY8CMBR3110_CY8CMBR3116-DataSheet-v18_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0ebe3508318e","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8CMBR3108-LQXIT support proximity detection?","answer":"Yes, proximity detection is supported.
