Product details

USB-to-I²C bridge for embedded control

The Infineon CY7C65211-24LTXI is a USB-to-I²C bridge from the CapSense® series, translating USB 2.0 traffic to an I²C bus for controlling sensors, GPIO expanders, or other I²C peripherals from a host PC or embedded USB port. It integrates the USB transceiver and protocol stack, so the host sees a standard HID or vendor-class device — no driver development needed for basic enumeration. The UART interface is also available on the same pins, giving a second serial path for debug or legacy device connections.

Supply range and current budget

The 1.71 V to 5.5 V supply range lets this bridge run off a 1.71 V to 5.5 V rail. At 20 mA typical supply current, it stays within the USB 2.0 bus-powered hub budget.

Frequently asked questions

Does CY7C65211 require an external crystal?

The evidence does not specify an external crystal requirement. The datasheet (available via the product page) covers the clocking scheme — check the oscillator section for your design.

Can CY7C65211 be used with Raspberry Pi?

Yes, the USB 2.0 interface and I²C output are compatible with a Raspberry Pi's USB host and I²C bus. The 1.71 V to 5.5 V supply range matches the Pi's 3.3 V or 5 V rail. No driver is needed for basic HID-class operation.
