The Aardvark I2C/SPI Host Adapter is a fast and powerful I2C bus and SPI bus host adapter through USB. It allows a developer to interface a Windows, Linux, or Mac OS X PC via USB to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols. Overview • I2C master and slave up to 800 kHz • I2C multi-master support • SPI master up to 8 MHz • SPI slave up to 4 MHz • GPIO with selectable pins I2C • True 800 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. The Aardvark I2C/SPI Host Adapter is compatible with: • Display Data Channel (DDC) • System Management Bus (SMBus) • Power Management Bus (PMBus) • Smart Battery Bus (SBBus) • Intelligent Platform Management Interface (IPMI) • Two-Wire Interface (TWI) Learn more about I2C in the I2C Background Article. † Actual system bus speed may vary as a function of capacitance. SPI • Operates in master or slave mode. • From 0.125 kHz 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 target power pins to power downstream devices. • Software configurable Slave Select (SS) polarity in master mode. Learn more about SPI in the SPI Background article. GPIO - General Purpose IO • 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. Low Cost The Aardvark adapter comes complete with a royalty-free API. The low cost makes it affordable for a company to provide every developer with their own interface. The benefits of every developer having their own interface are: • Less time wasted because developers do not have to share tools or go to the lab to debug simple problems. • Less wasted time means higher productivity because developers can identify and fix problems quickly and easily with less down-time. • Higher productivity means shorter development cycles. Projects get done on time and on budget • 深圳博瑞图电子科技有限公司 • TEL :0755-83244576 • MOB :13798234453 • QQ :52519094 • ADD :深圳市福田区中航路都会轩1416 • EMAIL :lijin810230@163.COM • 网 址：www.szprotools.com
