Description High-speed USB to I2C / SPI Bus Converter The TotalPhase Aardvark SPI & I2C Adapter is a fast and powerful SPI & I2C bus converter. With a feature-rich GUI application as well as an API supporting a whole list of languages and Labview drivers, this SPI / I2C adapter is suited to be used in the test lab environment as well as manufacturing and automated testing. I2C Bus Converter Specifications: True 400 kbps performance over higher bandwidth USB versus slower RS-232. Supports standard mode (100 kbps) and fast (400 kbps) mode as well as various speeds ranging from 1 kHz to 800 kHz. Supports inter-bit and inter-byte clock stretching. Supports multi-master. Master transmit and receive. Asynchronous slave transmit and receive. Software configurable I2C pull-up resistors. Software configurable target power pins to power downstream devices. Repeated Start, 10-bit slave addressing, and Combined Format transactions. Compatible with: Display Data Channel (DDC), System Management Bus (SMBus), Two-WireInterface (TWI) SPI Bus Converter Specifications: Operates in SPI master or slave mode. Up to 8 Mbps master signaling rate. Up to 4 Mbps slave signaling rate. Full-duplex master transmit/receive. Asynchronous slave transmit/receive. Software configurable Slave Select (SS) polarity in master mode General Purpose IO (GPIO) Specifications: I2C and SPI pins can be repurposed for more general use, allowing them to be used for custom signals on target systems. GPIO functionality can also be combined with I2C or SPI to interact with your target system. GPIO configuration is cached internally to preserve settings between operational modes. General Technical Specifications: SPI & I2C Converter is USB bus-powered Software configurable power output to power downstream devices (5V @ 30mA) 3.3V and 5V compatible ESD protection on all pins Firmware is field-upgradable OS support for Windows, Linux, and Mac The SPI & I2C Converter Package Includes: Aardvark I2C / SPI Adapter, USB cable, I2C / SPI data cable, CD with converter software, drivers, code examples, and documentation.
