Cypress’s EZ-USB FX3 is a SuperSpeed peripheral controller, providing integrated and flexible features.
FX3 has a fully configurable, parallel, general programmable interface called GPIF II, which can connect to any processor, ASIC, or FPGA. GPIF II is an enhanced version of the GPIF in FX2LP, Cypress’s flagship USB 2.0 product. It provides easy and glue less connectivity to popular interfaces, such as asynchronous SRAM, asynchronous and synchronous address data multiplexed interfaces, and parallel ATA.
FX3 has integrated the USB 3.1 Gen 1 and USB 2.0 physical layers (PHYs) along with a 32-bit ARM926EJ-S microprocessor for powerful data processing and for building custom applications. It implements an architecture that enables 375-MBps data transfer from GPIF II to the USB interface.
An integrated USB 2.0 OTG controller enables applications in which FX3 may serve dual roles

for example, EZ-USB FX3 may function as an OTG Host to MSC as well as HID-class devices.
FX3 contains 512 KB or 256 KB of on-chip SRAM. EZ-USB FX3 also provides interfaces to connect to serial peripherals such as UART, SPI, I2C, and I2S.
FX3 comes with application development tools.
FX3 complies with the USB 3.1, Gen 1.0 specification and is also backward compatible with USB 2.0. It also complies with USB 2.0 OTG Specification v2.0.
