Connects to and communicates with devices using I²C, SMBus, and SPI protocols.

The I²C/SPI Interface Device is a master or slave interface for inter-integrated circuit (I²C), or master interface for serial parallel interface (SPI) devices. With plug-and-play USB connectivity, the I²C/SPI Interface Device is a portable solution to communicate with consumer electronics and integrated circuits. The I²C/SPI Interface Device can be physically located more closely to I²C/SPI devices than PCI interfaces, reducing I²C bus length and minimizing noise problems. The I²C/SPI Interface Device supports I²C rates up to 250 kHz and SPI rates up to 50 MHz, and it also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I²C devices or toggling LEDs.
