Our Products

Aardvark I2C/SPI Host Adapter

The Aardvark I2C/SPI Host Adapter is a fast and powerful I2C 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 as a master or slave using the I2C and SPI protocols.

Beagle I2C/SPI Protocol Analyser

The Beagle I2C/SPI Protocol Analyser is a low-cost analyser that can monitor high-speed I2C (up to 4 MHz) and SPI (up to 24 MHz). Embedded engineers can use the Beagle I2C/SPI protocol analyser to monitor packet data in real-time, with 20 ns resolution bit-level timing. The Beagle I2C/SPI Protocol Analyser is ideal for embedded engineers and are perfect complements to the Aardvark I2C/SPI and Cheetah SPI Host Adapters.

Cheetah SPI Host Adapter

The Cheetah SPI Host Adapter is a high-speed SPI adapter that is capable of communicating over SPI at up to 40+ MHz. The Cheetah adapter is specifically designed to communicate with high-speed, SPI-based flash memory. It is an ideal tool to develop, debug, and program SPI-based systems.

Beagle USB 12 Protocol Analyser

The Beagle USB 12 Protocol Analyser is a non-intrusive full-/low-speed USB protocol analyser. This analyser can capture, display, and filter full-/low-speed USB activity in real time at 21 ns resolution. Whether developing hardware, firmware or software, the Beagle analyser is an invaluable tool that enables developers to see what is happening on the USB bus.

Beagle USB 480 Protocol Analyser

The Beagle USB 480 Protocol Analyser is a low-cost, non-intrusive high-/full-/low-speed USB 2.0 bus monitor. The Beagle analyser is capable of capturing, displaying, and filtering high-speed USB traffic and bus-states in real-time with timing at 16.7 ns resolution. Thanks to an on-board 64 MB buffer, sustained bursts of 480 Mbps traffic can be captured with no loss of data.

Beagle USB 480 Power Protocol Analyzer

Beagle USB 480 Power Protocol Analyser

The Beagle USB 480 Power Protocol Analyser is a low-cost, non-intrusive high-/full-/low-speed USB 2.0 bus monitor which enables VBUS current and voltage measurement within our industry-leading Data Center software. In addition to all the features included in our Beagle USB 480 Protocol Analyzer, the Power version also includes enhanced USB 2.0 advanced triggering, extra-large hardware buffer, and one-click correlation of voltage and current measurement to protocol-level activity ensures that engineers can take advantage of our unique real-time data analysis and display,

Beagle 5000 v2 SuperSpeed Protocol Analyzer

Beagle USB 5000 v2 Protocol Analysers

The Beagle USB 5000 v2 SuperSpeed Protocol Analyser, the winner of Best in Test 2012, is a world-class USB 3.0 bus monitor that provides real-time interactive capture and analysis of USB 3.0 and USB 2.0 (up to 5 Gbps). Now offering USB 3.0 downlink and multi-analyzer synchronization in the platform, we have created a blazing fast, advanced tool which is loaded with interactive and flexible features for even the most experienced USB developer. Free Data Center Software and cross-platform support for Windows, Linux, and Mac OS X make the Beagle USB 5000 v2 analyzer Ultimate a user-friendly and versatile tool for any engineer working with USB 3.0 or USB 2.0.

Promira Serial Platform

Promira Serial Platform

Promira Serial Platform is our most versatile and powerful serial device, supporting a variety of protocols, speeds, and features through varying levels of downloadable applications. This tool supports I2C, SPI, eSPI, and A2B protocols, and can support master clock speeds up to 80 MHz for SPI or 3.4 MHz for I2C. Among these features, this tool provides integrated level shifting, ethernet connectivity, and up to 200 mA of power. It the perfect tool for benchtop programming, testing, and emulation applications.

USB Power Delivery Analyzer

USB Power Delivery Analyser

USB Power Delivery Analyser is a small adapter that records the Power Delivery (PD) protocol traffic on the USB Type-C connector. It connects in-line between two Type-C products and passively captures all communication between them, on both the CC1 and CC2 signals. While connected, it does not disturb any USB 3.1 Gen 2 or USB 2.0 signals, enabling capture of PD negotiation for power, USB data roles, DisplayPort, or other Type-C Alternate Modes. Additionally, VBUS and VCONN are both monitored, graphing their current and voltage correlated in real-time to the captured data. 

Advanced Cable Tester v2

Advanced Cable Tester v2

Advanced Cable Tester v2 is Total Phase’s second generation, comprehensive cable testing solution that supports numerous cable types including USB, Apple Lightning, and video. This tool performs a complete analysis on each cable, testing for pin continuity, DC resistance, E-marker, Signal Integrity, and more to ensure compliance with the cable specification. Focused on mass-scale testing, users can obtain a complete report in seconds, providing clear results of a passing or failing cable. 


All Total Phase products are powered through USB and do not require an additional power adapter. All products support Windows, Linux, and Mac OS X and include free software, APIs, upgrades, and technical support. Whether developing I2C, SPI, MDIO, or USB products, Total Phase's high-performance, low-cost, and pocket-sized tools provide an ideal solution for every embedded systems engineer.
