• Manufacturer Part Number: CYUSB3014
• Description: EZ-USB FX3 SuperSpeed USB Controller UART support up to 4 Mbps
• Manufacturer: CYPRESS [Cypress Semiconductor]

Functional Overview
Cypress EZ-USB FX3 is the next generation USB3.0 peripheral
controller providing highly integrated and flexible features that
enable developers to add USB3.0 functionality to any system.
EZ-USB FX3 has a fully configurable, parallel, General
Programmable Interface called GPIF II, which can connect to
any processor, ASIC, or FPGA. The General Programmable
Interface GPIF II is an enhanced version of the GPIF in FX2LP,
Cypress’s flagship USB2.0 product. It provides easy and
glueless
asynchronous SRAM, asynchronous and synchronous Address
Data Multiplexed interface, parallel ATA, and so on.
EZ-USB FX3 has integrated USB3.0 and USB2.0 physical layer
(PHYs) along with a 32-bit ARM926EJ-S microprocessor for
powerful data processing and for building custom applications. It
implements an ingenious architecture which enables data
transfers of 320 MBps
An integrated USB2.0 OTG controller enables applications that
need dual role usage scenarios, for example EZ-USB FX3 may
function as OTG Host to MSC and HID class devices.

EZ-USB FX3 contains 512 kB of on-chip SRAM for code and
data. EZ-USB FX3 also provides interfaces to connect to serial
peripherals such as UART, SPI, I
EZ-USB FX3 comes with the easy to use EZ-USB tools providing
a complete solution for fast application development. The
software development kit comes with application examples for
accelerating time to market.
EZ-USB FX3 is fully compliant to USB3.0 v1.0 specification and
is also backward compatible with USB2.0. It is also complaint
with the Battery Charging Specification v1.1 and USB2.0 OTG
Specification v2.0.
