Trenz Electronic USB FX2 FPGA modules are devices that support USB 2.0 Hi-Speed communication with a host computer.
This document gives an overview of the USB FX2 technology stack supported by Trenz Electronic FPGA modules equipped with Cypress EZ-USB FX2 microcontroller (currently: TE0300, TE0320 and TE0630).

Trenz Electronic modules can be used with both couples of driver/API:
- DEWESoft device driver + DEWESoft API,
- Cypress device drivers + Trenz Electronic API(s),
but not a mix of the two:
- DEWESoft device driver + Trenz Electronic API(s),
- Cypress device driver + DEWESoft API.
Modules of both generations are factory programmed and tested with an open source reference architecture.
Capabilities
The reference architecture allows users to
- read and write the module SDRAM,
- read and write the Flash EEPROM,
- read and write the USB microcontroller EEPROM,
- read firmware version,
- reconfigure the FPGA
from a host application.
