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.

Not sure which product is right for your needs? The Product Selector Guide provides a summary table of key features for our I2C/SPI Total Phase products.

Detailed technical information about the Aardvark I2C/SPI adapter can be found in the User Manual.

We also have a Quick Start Guide to help you get started.

  • 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

Actual system bus speed may vary as a function of capacitance.

What is Included
  • 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.

  • Operates in 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 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.

By saving just a few hours of engineering time, the Aardvark adapter will have paid for itself.


The Aardvark adapter is completely field-upgradable via USB. Total Phase is committed to improving the Aardvark adapter and making these improvements available to our customers.

You will never have to worry about being out of step with the latest software features. Eligible Software and firmware upgrades are always freely available in the Downloads section of this website.
