Datasheet CYUSB3304-68LTXI

Infineon USB Controller, 68 Pins, Surface Mount Type - CYUSB3304-68LTXI

This USB controller is a compact Infineon device designed to manage multiple USB transceivers within embedded systems. It operates from a single power rail and is intended for surface-mounted integration where board space and vertical profile are constrained. The component includes electrostatic discharge safeguarding and is specified for extended temperature environments common in mobile and automotive-adjacent electronics.

Features and Benefits:

• Four transceivers enabling multi-channel USB connectivity
• Single-supply operation simplifying power-rail design
• ESD protection reducing risk from electrostatic events
• Surface-mount QFN package for automated assembly
• Broad temperature range supporting harsh environments
• Low-profile package aiding slim system designs

Applications

• Suitable for multi-port USB hubs in compact devices
• Ideal for in-vehicle infotainment interface modules
• Used with industrial controllers requiring robust I/O
• Can be used for portable electronics with limited height
• Appropriate for automotive-adjacent sensor communication systems

What pin count should I plan for on the PCB footprint?

The device uses a 68-pin layout, so the board footprint and routing must accommodate that pin count.

How does the package influence thermal management on the PCB?

The QFN format provides a short thermal path to the board

designers should include thermal vias and copper pours beneath the package to aid heat dissipation.

What assembly considerations are important for this component?

As a surface-mount QFN, it requires precise solder paste deposition and reflow profiles suitable for low-profile packages to ensure reliable joints.

Which environmental range can the device handle during operation?

It is rated to function from -40°C up to 85°C, covering a wide span of operating conditions.
