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.

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.
