Infineon Technologies has developed a 20Gbit/s programmable USB controller that it says in an industry first.
The Infineon EZ-USB FX20 programmable USB controller is aimed at AI, image processing and emerging applications. The 20Gbit/s USB interface and LVDS interface increase the total bandwidth up to six times over its predecessor, the 10Gbit/s EZ-USB FX3.
The programmable USB controller uses two ARM Cortex-M4 and M0+ cores, 512 KB Flash, 128 KB SRAM, 128 KB ROM and seven serial communication blocks (SCBs). It also includes a cryptography accelerator and a high-bandwidth data subsystem that enables Direct Memory Access (DMA) data transfers between LVDS/LVCMOS and USB ports at speeds of up to 20 Gbit/s.
Data transfer is also supported by an additional 1 MB of SRAM for USB data buffering. As the peripheral controller integrates USB-C port orientation detection and flip-mux functionality, no external logic is required.
The 10 x 10 mm² BGA package requires little PCB space and supports direct USB-C connection without a high-speed signal multiplexer, simplifying the design process.
A quick-start development kit includes firmware and a configuration tool for easy integration. It comes with a standard FPGA Mezzanine Card (FMC) connector for easy connection to Field Programmable Gate Array (FPGA) cards and an all-in-one programming and debugging accessory card.
Infineon also has a set of application notes for hardware and software design to simplify the development of high-performance devices for various applications.
“With the growing popularity of USB devices, the demand for compatible and adaptable USB controllers is increasing,” said Ganesh Subramaniam, Senior Vice President and General Manager of the Wired Connectivity Solutions Product Line at Infineon. “Therefore, we are continuously improving the features and performance of our EZ-USB peripheral controllers and are pleased to support developers with our new addition to the product family, providing them with a flexible component to create powerful and advanced applications.”
The EZ-USB FX20 programmable USB controller in a 10 x 10 mm² BGA package will be available in the first quarter of 2025. Development samples are available now. It will be previewed at VISION, the international trade fair for industrial image processing at Messe Stuttgart, from October 8 to 10.
