I²C/​SPI Interface Device

​查看​产品​详情 ​

​ ​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 SCSI 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.
