It belongs to the CapSense® series, though its primary function here is the bridge, not capacitive sensing. The 24-UFQFN package with exposed pad (4x4mm) keeps the footprint small for space-constrained designs like portable instruments or embedded modules. The 1.71V to 5.5V supply range covers both legacy 3.3V logic and newer 1.8V-core systems, plus it can drive 5V-tolerant I²C buses without a level shifter. That saves a translator IC and the board area it would take. The 20mA supply current is the active draw during USB communication — budget for it on the 3.3V or 5V rail, but it's low enough that a standard linear regulator can feed it without thermal concern. No derating needed for ambient temperatures inside a ventilated enclosure. ## Package and layout — the exposed pad matters The 24-UFQFN with exposed pad is a 4x4mm body with a thermal pad underneath. The pad also serves as a low-inductance ground return for the USB signals, which helps with signal integrity on the D+ and D- lines.","metaTitle":"Infineon CY7C65211A-24LTXI USB-to-I2C/SPI/UART Bridge","metaDescription":"Infineon CY7C65211A-24LTXI CapSense® USB 2.0 bridge with UART, I2C, SPI interfaces. 1.71V-5.5V supply, -40°C to 85°C, 24-QFN.","metaKeywords":null},"attributes":{"series":"CapSense®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"CapSense®","Package":"Tray","Function":"Bridge, USB to I²C","Protocol":"USB","Interface":"UART","Standards":"USB 2.0","Package / Case":"24-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"20mA","Voltage - Supply":"1.71V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-QFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.53000","currency":"USD"},{"qty":10,"price":"$3.17300","currency":"USD"},{"qty":25,"price":"$2.99960","currency":"USD"},{"qty":80,"price":"$2.59975","currency":"USD"},{"qty":230,"price":"$2.46643","currency":"USD"},{"qty":490,"price":"$2.21310","currency":"USD"},{"qty":980,"price":"$1.86648","currency":"USD"},{"qty":2450,"price":"$1.77316","currency":"USD"},{"qty":4900,"price":"$1.70650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1d7b39ce00deaf9556f3089860f05b65.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C65211A-24LTXI compatible with USB 2.0?","answer":"Yes, it implements the USB 2.0 standard, so it connects directly to any USB 2.0 host port at full-speed (12 Mbps) data rates."},{"question":"What is the equivalent or replacement for CY7C65211A-24LTXI?","answer":"The CY7C65213-28PVXIT is a functional sibling in the same USB bridge family, but it is a USB-to-UART only part — it lacks the I²C and SPI interfaces that the CY7C65211A-24LTXI provides.
