Trenz Electronic USB FX2 FPGA modules are devices that support USB 1.1 and USB 2.0 Hi-Speed communication with a host computer. Low-power downstream ports (capable of sourcing 100 mA or less) are not supported. High-power downstream ports (capable of sourcing at least 500 mA) are supported.
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.
