It handles keypad scanning, GPIO expansion, and interrupt management, offloading these tasks from the main application processor. The supply voltage range is 2.25V to 2.9V, a narrow window that demands a regulated rail — a direct 3.3V supply will exceed the absolute maximum. A small LDO or buck regulator from a 3.3V or battery rail is the typical approach. Quiescent current is 6 mA typical, low enough for battery-powered handsets and wearables where every milliamp of standby draw is budgeted. ## Package and PCB layout — the exposed paddle matters The part comes in a 32-WFQFN Exposed Pad package, 6x6 mm body. The exposed paddle on the underside must be soldered to a thermal land on the PCB, with vias to a ground plane to keep junction temperature within limits. The 0.5 mm pitch QFN demands careful solder-paste stencil design — a 4-layer board is recommended for fan-out and thermal relief. Listed package form is Bulk, meaning the parts ship in tubes or trays rather than tape-and-reel. If your pick-and-place line expects reeled parts, confirm the packing option or plan for a tube feeder. ## Active lifecycle — no end-of-life pressure New designs can proceed without the sourcing clock ticking.","metaTitle":"LM8333FLQ8X/NOPB Mobile I/O Companion Controller","metaDescription":"Texas Instruments LM8333FLQ8X/NOPB mobile I/O companion controller with I²C/ACCESS.bus interface, 2.25V–2.9V supply, 6 mA supply current, 32-WFQFN exposed pad","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Package":"Bulk","Function":"Controller","Interface":"ACCESS.bus, I²C","Package / Case":"32-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"6mA","Voltage - Supply":"2.25V ~ 2.9V","Supplier Device Package":"32-WQFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.74","stockQuantity":0,"priceTiers":[{"qty":173,"price":"$1.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/jy6ng5xsun/NATLS11412-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"Does LM8333 support I²C or ACCESS.bus?","answer":"Yes, the LM8333 supports both I²C and ACCESS.bus interfaces, allowing it to communicate with modern I²C hosts and legacy ACCESS.bus peripherals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM8333FLQ8X-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM8333FLQ8X-NOPB when reusing this data.
