Serial buses on AVR and AVR32
All AVR and AVR32 microcontrollers feature multiple I2C (TWI) and SPI buses for interfacing with peripheral devices such as EEPROMs, flash chips, sensors, ADC/DAC, and more. Total Phase offers a wide range of I2C and SPI tools that can rapidly simulate, program, exercise, and passively monitor these serial buses.

Aardvark I2C/SPI Host Adapter
The Aardvark I2C/SPI Host Adapter is a low-cost USB interface that allows developers to send and receive data as an I2C/SPI master or slave from a Windows, Linux, or Mac OS X PC. This versatile tool is indispensable for debugging embedded systems. The Aardvark adapter can be used to emulate master or slave devices, in-system programming, configuration of I2C or SPI peripherals, automated test fixtures, and much more.
Beagle I2C/SPI Protocol Analyzer
The Beagle I2C/SPI Protocol Analyzer is a low-cost, non-intrusive USB-based bus monitor for I2C and SPI. This analyzer can display I2C bus traffic at up to 4 MHz and SPI bus traffic at up to 24 Mhz in real-time, with bit-level timing resolution of 20 ns. The analyzer fully supports Windows, Linux, and Mac OS X, and is an excellent complement to the Aardvark and Cheetah host adapters.
Cheetah SPI Host Adapter
The Cheetah SPI Host Adapter is an efficient high-speed SPI adapter over USB. Reaching speeds of up to 40+ MHz without gaps, the Cheetah adapter is an excellent tool for in-system programming of serial flash memory, streaming data applications, and more.
USB on AVR and AVR32
AVR32 AP7
The AVR32 AP7 microcontroller features a built-in 480 Mbps USB PHY which allows developers to develop high-speed USB-based embedded hosts or devices.
AVR32 UC3
The AVR32 UC3 microcontroller provides full-speed USB (12 Mbps) and On-The-Go capability for creating the next generation of plug-and-play devices.
