It handles up to 10 button inputs and drives up to 10 LED channels directly, with the tuning done through the I²C interface — no firmware development required. ## Supply voltage and I/O — what fits the BOM The 1.71 V minimum supply is low enough to work with a deeply discharged lithium cell, and the 5.5 V maximum covers 5 V logic and unregulated USB VBUS. The 10 button inputs are self-capacitance only — there is no proximity detection on this variant, so if you need a wake-on-approach gesture, look at the CapSense proximity-enabled siblings. Each of the 10 LED driver channels can sink enough current for a standard indicator LED, eliminating a separate LED driver IC on the board. ## Package and temperature grade for the environment The 32-QFN (5x5 mm) with exposed pad (32-UFQFN Exposed Pad) is a compact surface-mount package suited for dense PCBs. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"Cypress CY8CMBR2110-24LQXI CapSense Express 10-button","metaDescription":"Cypress CY8CMBR2110-24LQXI CapSense Express capacitive touch controller with 10 button inputs, 10 LED drivers, I²C interface, 1.71V-5.5V supply, -40°C to 85°C","metaKeywords":null},"attributes":{"series":"CapSense® Express™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Buttons","Series":"CapSense® Express™","Package":"Tray","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"32-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"3.4mA","Number of Inputs":"Up to 10","Voltage - Supply":"1.71V ~ 5.5V","LED Driver Channels":"Up to 10","Proximity Detection":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"32-QFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.98000","currency":"USD"},{"qty":10,"price":"$4.47100","currency":"USD"},{"qty":25,"price":"$4.22680","currency":"USD"},{"qty":80,"price":"$3.66325","currency":"USD"},{"qty":230,"price":"$3.47539","currency":"USD"},{"qty":490,"price":"$3.11847","currency":"USD"},{"qty":980,"price":"$2.63004","currency":"USD"},{"qty":2450,"price":"$2.49854","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6ed1c0ba1124a8a4470d47ee4c012bec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8CMBR2110-24LQXI have proximity detection?","answer":"No. This variant does not include proximity detection.
