Infineon CYUSB330 Series USB Controller, 480 Mbps Maximum Data Rate, 3.3V Minimum Supply Voltage - CYUSB3304-68LTXC

This USB controller is a surface-mount device intended to manage high-speed USB links in electronic designs. It implements the USB 3.0 protocol and is suited to applications where compact integration and controlled power consumption are required. The component is supplied from a single 3.3V rail and is offered in a QFN package optimised for PCB mounting.

Features and Benefits:

• 480 Mbps data throughput for high-speed transfers
• 4 transceivers enabling multiple SuperSpeed endpoints
• 272 mA supply current for predictable power budgeting
• ESD protection to reduce damage from electrostatic events
• Operation across 0-70 °C for varied ambient conditions

Applications

• Used for connecting SuperSpeed peripherals on embedded boards
• Suitable for industrial communication interfaces requiring USB 3.0
• Ideal for high-bandwidth data-acquisition modules on PCBs
• Can be used for external storage enclosures with surface mounting
• Used with multi-channel USB hubs requiring several transceivers

What package type should designers plan for on the PCB?

A QFN footprint is required for correct thermal and electrical contact and to accommodate the 68-pin arrangement during assembly.

How does supply arrangement affect system power design?

The device operates from a single 3.3V supply and draws 272 mA under typical conditions, which helps define regulator capacity and thermal dissipation needs.

What environmental limits must be observed during operation?

The component is specified to function between 0 °C and 70 °C, so system cooling and placement should maintain temperatures within that band.

How many transceiver channels are available for data paths?

There are four transceivers provided, allowing multiple SuperSpeed data lanes or parallel USB connections as required.
