USB to I2C Elite

USB to I2C Elite is a general purpose I2C interface tool that allows a user to communicate with any I2C slave device. USB-to-I2C Elite includes the USB-based hardware and Windows downloadable software which is compatible with Windows XP, Vista, Windows 7,  8, 10 and Windows 11. Windows drivers are available for 64-bit operating systems.  Click on our Software Overview tab above to view I2C Device part numbers which are supported.

The downloadable for the USB to I2C Elite software has the capability to program I2C serial eeproms from 16 bytes (128 bits) to 512k bits (64k bytes). Two universal modes provide the flexibility to communicate with any I2C device. In addition to the eeprom/ram/fram support, the USB-to-I2C application has built in support for over 72 specific I2C devices (see description below) which is useful for debugging hardware containing these common devices. The SPI software can be used for EEPROMs, as well as most other SPI devices.

The USB to I2C Elite hardware is capable of transmitting up to 1 Mb/s (note the I2C spec limits the speed to 400 Kb/s) and SPI up to 30 Mb/s. There are 3.3V and 5V power outputs on the USB-to-I2C hardware allowing you to power low-power target systems. The hardware can be used as a master-transmitter, master-receiver, slave-transmitter, and slave-receiver.

A DLL is included with the USB to I2C Elite that can be used to create your own custom I2C, SMBus, and SPI applications. Examples using Visual C++, Visual Basic, Delphi, and C++ Builder are provided. The DLL is compatible with LabView.
