EZ-USB™ SX3: Configurable SuperSpeed USB 3.2 Gen 1 Controller

Overview

Universal Serial Bus (USB) integration, configurable interface and ultra low-power in core power-down mode

Infineons’ EZ-USB™ SX3 is a Configurable SuperSpeed peripheral controller, providing integrated and flexible features. SX3 has a fully configurable, parallel interface called General Configurable Interface, which can connect to any ASIC, ISP, image sensor or FPGA that supports Slave FIFO or Video interface.

SX3 has integrated the USB 3.2 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 General Configurable Interface to the USB interface.

SX3 contains 512 KB of on-chip SRAM for code and data. EZ-USB SX3 also provides interfaces to connect to serial peripherals such as SPI and I2C.

SX3 comes with “SX3 Configuration Utility”, that will help customers to configure the SX3 for various applications. This tool can also merge the FPGA configuration or ISP firmware along with SX3 configuration and stores it in a single SPI Flash. SX3 complies with the USB 3.2 Gen 1 specification and is also backward compatible with USB 2.0.

EZ-USB SX3 Configuration Utility is a graphical user application that allows users to configure the EZ-USB SX3 USB 3.2 Gen 1 Device controller variants. The user can completely configure the EZ-USB SX3 based on the system requirements. The tool supports configuration of SX3-UVC and SX3-Data variants. Users can configure the following using EZ-USB Configuration Utility for each variant:

SX3-UVC (CYUSB3017 - variant supporting UVC and UAC)

  • USB descriptor settings: Vendor ID, Product ID, String descriptors (Product, Manufacturer, Serial Number), Remote wakeup configuration,
  • GPIO configuration
  • Debug interface
  • FPGA, HDMI receiver, or ISP configuration
  • DMA buffer configuration
  • UVC video formats and resolutions
  • Camera terminal controls
  • Processing unit controls
  • Extension unit controls
  • Image sensor / HDMI RX configuration
  • Audio interface configuration

SX3-Data (CYUSB3015, CYUSB3016 - variant supporting USB vendor class)

  • USB descriptor settings: Vendor ID, Product ID, String descriptors (Product, Manufacturer, Serial Number), Remote wakeup configuration
  • GPIO configuration
  • Debug interface
  • FPGA configuration
  • Buffer configuration

Users can also program the created configuration into the EX-USB SX3 using the programming tool integrated into the utility. This utility allows the user to save the created configuration. It also allows users to load the selected configuration. The utility is supported across Windows, Linux and Mac OSX platforms.
