Infineon’s High-Throughput USB 2.0 Controller

Infineon Technologies has recently unveiled the EZ-USB FX2G3, a USB 2.0 peripheral controller that expands its USB portfolio. This new controller is specifically designed for applications that demand higher data throughput, deterministic latency, and tighter system integration. It is targeted at a wide range of industries, including industrial, consumer, and embedded system designs where USB remains a prevalent interface choice.

For readers in the embedded platforms space, the introduction of the EZ-USB FX2G3 is significant. USB 2.0 continues to be extensively used in industrial automation, test equipment, and consumer peripherals, often in conjunction with newer interfaces. Updates like this can potentially streamline system architecture and prolong the lifespan of existing USB-based platforms.

Focus on embedded system integration

The EZ-USB FX2G3 is engineered to cater to high-bandwidth USB 2.0 applications while incorporating features that could minimize the reliance on external components. Infineon positions this controller for systems that merge USB connectivity with local processing and real-time data handling, such as industrial sensors, robotics subsystems, and human–machine interface devices.

This device offers flexible interface options for connecting to external processors, FPGAs, or sensors, making it suitable for a variety of embedded architectures. Infineon also emphasizes security-related functions to support authenticated firmware and controlled device behavior, which is increasingly crucial in industrial and connected environments.

Target applications and performance considerations

Infineon has identified several target applications for the EZ-USB FX2G3, including industrial automation, robotics, and consumer electronics peripherals. In industrial systems, it can facilitate real-time data acquisition and control tasks, while in consumer designs, it is ideal for applications like gaming accessories and audio peripherals.

Although USB 2.0 may not offer the bandwidth of newer USB standards, Infineon is focusing on designs where determinism, compatibility, and long-term availability take precedence over raw throughput. In this context, the USB 2.0 peripheral controller approach may appeal to engineers looking to maintain or extend established product platforms rather than adopting entirely new interface standards.

Availability and packaging

The EZ-USB FX2G3 comes in a 104-pin LGA package with an 8 × 8 mm footprint. Infineon has confirmed that samples, documentation, and development support are readily available, with volume production being supported for long-term deployment scenarios.
