Advanced portable and wearable wireless devices need a good device interface for fast charging and data transfer. Addressing this demand, Infineon Technologies launched the EZ-USB FX20 programmable USB peripheral controller. It opens the door to the creation of USB devices for the demanding requirements in AI, image processing, and emerging applications.
Offering high-speed connectivity with USB 20-Gb/s and LVDS interfaces, the EZ-USB FX20 has a bandwidth up to 6X greater than legacy devices.
“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.”
Well-suited for space-constrained applications, the EZ-USB FX20 comes in a 10- × 10-mm2 BGA package. The controller enables BOM optimization and supports direct USB-C connection without a high-speed signal multiplexer.
A quick-start development kit includes firmware and there's a configuration tool for easy integration. Also included is a standard FPGA Mezzanine Card connector for FPGA cards and an all-in-one programming and debugging accessory card. Furthermore, the peripheral controller offers application notes for hardware and software design to address various applications.
Among its other features are two Arm Cortex-M4 and M0+ core CPUs, 512-kB flash, 128-kB SRAM, 128-kB ROM, and seven serial communication blocks. A cryptography accelerator and a high-bandwidth data subsystem handles direct-memory-access data transfers between LVDS/LVCMOS and USB ports. Data transfer is also supported by an additional 1 MB of SRAM for USB data buffering. The controller integrates USB-C port orientation detection and flip-mux functionality as well, eliminating the need for external logic.
