Infineon CYUSB3014-BZXC, Controller IC, 1-Channel 5 Gbps, 1.25V, USB 2.0, 1.2 V, 121-Pin BGA

This controller IC provides USB 2.0 interfacing and protocol control for embedded systems requiring a single-supply solution. Designed for surface-mounted PCB integration, it supports data transfer rates typical of USB 2.0 and includes electrostatic discharge protection for robust signal integrity. The device operates across a moderate commercial temperature window and is intended for applications needing a compact, high-functionality controller in a BGA package.

• 5Gbps capability enables high-throughput USB signalling
• Single supply 1.2-1.25V simplifies power-rail design
• 121 pins provide extensive I/O and routing options
• Built-in ESD protection reduces risk during handling
• Supports a single transceiver for streamlined implementation
• Surface-mount BGA facilitates dense PCB layouts

• Suitable for industrial peripherals requiring USB 2.0 connectivity
• Ideal for embedded host or device controller implementations
• Used with compact consumer electronics requiring minimal power rails
• Can be used for gateway modules in constrained spaces
• Appropriate for development boards needing high-pin-count interfaces

The device requires a supply within 1.2V minimum to 1.25V maximum, so power regulation must maintain that window for stable operation.

It is supplied in a BGA package with a low profile, so precise solder mask definition and reflow-profile control are necessary for reliable joints.

It is rated to operate from 0°C up to 70°C, so thermal management should ensure ambient and PCB heating keep junctions within that span.

The part supports USB 2.0 protocol and integrates one transceiver to handle differential USB signalling.
