Win-I2CUSBDLL is a complete I²C software/adapter bundle which includes the Win-I2CUSB application for control of  I²C/SMBus devices (Win-I2CUSB GUI is cosmetically similar to the Win-I2CNT application).

The USB-based host adapter supports 400kb/s  I²C Master operations (800-1000 kb/s  I²C communication is possible, but these speeds are not guaranteed, and not supported in the 400kb/s  I²C specification).

The software has the capability to program I2C and SPI serial EEproms and Ram/ Fram device sizes ranging from 16Kb (128 bit) to 512Kb (64K bytes). Universal modes allow flexibility to communicate most  I²C compatible devices.

The  I²C adapter is USB powered and can also supply limited 3.3v/5v power to a low power I2C target application (50mA max).

The Win-I2CUSB software, DLL, and USB driver are compatible with Windows (x86)  2000, XP, and Vista.
Software updates are downloaded via the built-in update utility (requires internet connection).

The  DLL was developed specifically for the included Win-I2CUSB adapter to allow creation of custom applications in other environments such as Delphi, Visual Basic, MSVisual C++, C++ Builder, VB.Net,  and Visual C++.Net. Refer to the DLL User Manual on the FAQ page for details (link below).

The Win-I2CUSBDLL kit includes a single user license for Win-I2CUSB and the DLL.
