It handles up to 16 capacitive touch inputs and integrates up to 16 LED driver channels for backlighting or status indicators, eliminating the need for a separate GPIO expander or LED driver IC. The supply voltage range spans 1.71V to 5.5V, covering 3.3V and 5V logic rails as well as single-cell Li-ion down to near-depletion. Typical supply current is 3.3 mA, making it viable for always-on touch panels in battery-powered handhelds. ## Industrial temperature grade — deployment environments Rated for -40°C to 85°C, this part fits industrial and outdoor equipment: factory automation HMI panels, outdoor kiosks, commercial appliance front panels, and automotive cabin touch controls where the ambient stays below 85°C. The 48-UFQFN package with exposed pad needs a thermal via array under the pad for heat spreading — the 3.3 mA draw is modest, but the LED driver outputs can sink higher current per channel, and the pad keeps junction temperature in check when driving multiple LEDs. ## Lifecycle and sourcing posture Cypress lists the CY8CMBR2016-24LQXI as an active product — no last-time-buy notice, no NRND flag. This means it can be specified into new designs without an obsolescence risk horizon. For volume production, the active status supports multi-year supply commitments. ## What the 16-button and 16-LED-channel count means for BOM consolidation Sixteen capacitive inputs cover a typical appliance or industrial keypad — numeric pad, navigation cluster, dedicated function keys. The matching 16 LED driver channels mean each button can have its own backlight or status LED without external transistors or a separate LED controller. This integration collapses what would otherwise be an MCU with firmware, a touch IC, and an LED driver into a single configurable device. No proximity detection is available, so this part is for contact-only touch buttons, not hover or wake-on-approach.","metaTitle":"CY8CMBR2016-24LQXI CapSense Express capacitive button","metaDescription":"Cypress CY8CMBR2016-24LQXI capacitive touch button controller with 16 inputs, 16 LED driver channels, 1.71V-5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"CapSense® Express™","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Buttons","Series":"CapSense® Express™","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"48-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"3.3mA","Number of Inputs":"Up to 16","Voltage - Supply":"1.71V ~ 5.5V","LED Driver Channels":"Up to 16","Proximity Detection":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-QFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.24000","currency":"USD"},{"qty":10,"price":"$5.60100","currency":"USD"},{"qty":25,"price":"$5.29480","currency":"USD"},{"qty":80,"price":"$4.58888","currency":"USD"},{"qty":230,"price":"$4.35361","currency":"USD"},{"qty":490,"price":"$3.90647","currency":"USD"},{"qty":980,"price":"$3.29462","currency":"USD"},{"qty":2450,"price":"$3.12989","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9de701eab8601ac234845d09dd0b3861.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many capacitive buttons can the CY8CMBR2016-24LQXI control, and does it have integrated LED drivers?","answer":"It controls up to 16 capacitive touch buttons and integrates up to 16 LED driver channels for button backlighting or status indication.
