Product details

2-port USB 3.0 hub with integrated MCU

The CYUSB3312-88LTXI is a 2-port USB 3.0 hub controller from the HX3 series, integrating an ARM Cortex-M0 core with 32KB of ROM for firmware and a 16K x 8 RAM buffer for data transactions. It operates across three supply rails — 1.14V to 1.26V core, 2.5V to 2.7V, and 3V to 3.6V I/O — giving the board designer flexibility to match existing power trees without an extra regulator. The I²C interface allows the host to configure hub parameters or read status registers, which is useful for systems that need to disable ports on overcurrent or adjust charging-downstream current limits without a firmware update.

Package, temperature, and board integration

With 10 general-purpose I/O lines, the controller can drive status LEDs, reset signals, or port-power enable FETs directly, reducing the need for external GPIO expanders.

RoHS3 compliant, with no halogen or lead restrictions that would block EU or California market entry.

Frequently asked questions

What is the difference between CYUSB3312-88LTXI and CYPD2122-24LQXIT?

The CYPD2122-24LQXIT is a USB Type-C controller with a FLASH-based program memory and SPI/UART interfaces, while the CYUSB3312-88LTXI is a dedicated 2-port USB 3.0 hub with ROM firmware and I²C only — they serve different functions and are not drop-in replacements.

What compliance documentation does Infineon provide for CYUSB3312-88LTXI?

Infineon provides RoHS3 compliance certification; no UL or IEC documentation is listed in the record.
