The 28 general-purpose I/O pins give headroom for scanning a 12- to 16-key matrix plus LED feedback, all without an external multiplexer. Supply range spans 1.71 V to 5.5 V, so the same part can sit on a 1.8 V core rail or a 5 V legacy backplane. ## Package and footprint — 32-UFQFN with exposed pad The Tape & Reel shipping format (Cut Tape also available) suits automated pick-and-place lines. ## Interface and application fit Communication with a host processor runs over I²C or SPI — both are available on-chip. The I²C interface can operate as a slave at standard and fast-mode speeds, which is the typical hookup for a touch-sensor panel reporting to a main application MCU. The SPI port can be used for higher-throughput data transfer or to daisy-chain multiple CapSense controllers on the same bus. ## Lifecycle status — active, no LTB pressure Infineon lists the CY8C20446A-24LQXIT with an Active product status. This is not a shortage-risk line item for the foreseeable production horizon.","metaTitle":"CY8C20446A-24LQXIT CapSense Controller, 16KB Flash, 2K RAM","metaDescription":"Infineon CY8C20446A-24LQXIT CapSense controller with M8C core, 16KB Flash, 2K x 8 RAM, I²C/SPI interface, -40°C to 85°C, 32-UFQFN.","metaKeywords":null},"attributes":{"series":"CapSense® Controllers","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"CapSense® Controllers","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Interface":"I²C, SPI","Applications":"Capacitive Sensing","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"M8C","Package / Case":"32-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 5.5V","Controller Series":"CY8C20xx6A","Program Memory Type":"FLASH (16kB)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"32-QFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.71000","currency":"USD"},{"qty":10,"price":"$6.05800","currency":"USD"},{"qty":25,"price":"$5.77680","currency":"USD"},{"qty":100,"price":"$5.01590","currency":"USD"},{"qty":250,"price":"$4.79044","currency":"USD"},{"qty":500,"price":"$4.36774","currency":"USD"},{"qty":1000,"price":"$3.80416","currency":"USD"},{"qty":2500,"price":"$3.66327","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e8bac9edb4347eb29d3d0f2ffcdd8999.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CY8C20446A-24LQXIT and CY8C20446A-24LQXI?","answer":"The suffix 'T' in CY8C20446A-24LQXIT indicates Tape & Reel packaging, while CY8C20446A-24LQXI is the tray or tube variant.
