Total Phase: host adapters and protocol analysers for debug

Total Phase makes USB-connected host adapters and protocol analysers for I2C, SPI, eSPI, USB and CAN. A host adapter lets a PC act as a bus master or slave to program, control and test a device; a protocol analyser sits on the bus and records what other devices say. Total Phase supplies the hardware, free Control Center and Data Center software, and a royalty-free API for your own test scripts.

Host adapter or protocol analyser: active versus passive

A host adapter is active: it drives the bus, so the PC can read an EEPROM, program a flash or exercise a sensor. A protocol analyser is passive: it listens to traffic between two other devices and decodes it without transmitting. Total Phase sells both, and the Promira Serial Platform can do either depending on the applications loaded.

A host adapter transmits on the bus; a protocol analyser only records it.

Total Phase products by bus

For I2C and SPI the choice is Aardvark, Cheetah or Promira to drive a device, and Beagle I2C/SPI or Promira to analyse one. Total Phase USB analysis is covered by the Beagle USB range, CAN by the Komodo CAN Duo, and eSPI by a Promira with the eSPI Analysis application.

Pick the bus first, then decide whether you need to drive it or only watch it.

Aardvark, Cheetah and Promira: which host adapter?

The Aardvark suits general I2C and SPI development, the Cheetah suits fast SPI flash work, and the Promira covers faster I2C, Quad SPI and remote use. The Aardvark speaks both I2C and single-lane SPI. The Cheetah is SPI only and targets large memory writes and production flash programming. The Promira is an FPGA-based platform whose capabilities are set by licensed applications, which you can add later without changing the hardware:

I2C Active: Level 1 to 1 MHz, Level 2 to 3.4 MHz (High-Speed mode).
SPI Active: Level 1 at 12.5 MHz master and 8 MHz slave, Level 2 at 40 MHz master and 20 MHz slave, Level 3 at 80 MHz master and 20 MHz slave with Quad I/O.
eSPI: the eSPI Analysis Application monitors eSPI at up to 66 MHz in single, dual and quad modes. The Promira eSPI Bus Analyser Kit bundles the platform, the application and Data Center.

Aardvark and Cheetah need an accessory board such as the Level Shifter Board for voltage translation; the Promira has level shifting built in.

Beagle protocol analysers

Beagle analysers capture traffic non-intrusively and stream it to Data Center. The Beagle I2C/SPI Analyser decodes I2C and SPI. For USB, the Beagle USB 12 covers low and full speed, the Beagle USB 480 adds high speed with an on-board buffer, the Beagle USB 480 Power Ultimate also records VBUS current and voltage, and the Beagle USB 5000 v2 Ultimate adds USB 3.0 SuperSpeed. For wiring, see the Beagle USB connections guide.

Komodo CAN Duo

The Komodo CAN Duo is a two-channel USB-to-CAN interface that can transmit on one channel while monitoring on the other. Each channel has independent galvanic isolation and runs up to 1 Mbps, and the unit has 8 configurable GPIO lines. Accessories include the CAN Bus Terminator, the CAN Bus Split Cable and the CAN/I2C Activity Board Pro. Pin assignments are on the Komodo CAN pinout page.

Software and API

Total Phase software is free to download and runs on Windows, Linux and macOS.

Control Center Serial Software: controls Aardvark, Cheetah and Promira. Send and receive I2C or SPI data as master or slave, configure GPIO, log transactions to CSV and automate tasks with XML batch scripts.
Data Center Software: captures and displays I2C, SPI, USB, eSPI and CAN data from the Beagle analysers, Promira (eSPI) and Komodo CAN Duo, with LiveDisplay, LiveFilter and LiveSearch.
Flash Center: programming software supplied with the Promira.
API: a royalty-free software API lets you script the hardware from your own code. Language support depends on the product; the Promira lists C, Python, Visual Basic and C#, and the Komodo lists C/C++, .NET, Python and Visual Basic. LabVIEW drivers are available for the Komodo and Beagle analysers.

Connector layouts are on the Aardvark pinout and I2C and SPI pinouts pages. Split cables such as the 10-pin Split Cable, the Split Cable with Grabbers and the 34-pin Split Cable break the connector out to your target.

Typical applications

Bringing up and validating I2C and SPI peripherals, sensors and EEPROMs with an Aardvark and the I2C Development Kit
Programming SPI flash on the bench or in production with a Cheetah and the SPI Development Kit
Debugging timing and protocol faults between devices on an I2C or SPI bus with a Beagle I2C/SPI Analyser
USB device and host development, enumeration and power debugging with the Beagle USB analysers
Automotive, industrial and medical CAN bus monitoring and message injection with the Komodo CAN Duo
Embedded-controller and eSPI debugging with the Promira eSPI Bus Analyser Kit

Frequently asked questions

What is the difference between a host adapter and a protocol analyser?

A host adapter such as the Aardvark drives the bus as a master or slave so you can control a device. A protocol analyser such as the Beagle I2C/SPI Analyser only listens and decodes traffic between other devices.

Should I buy an Aardvark, a Cheetah or a Promira?

Choose the Aardvark for I2C and SPI up to 800 kHz and 8 MHz, the Cheetah for SPI up to 40 MHz, and the Promira for I2C to 3.4 MHz, SPI to 80 MHz, Dual and Quad SPI, built-in level shifting and Ethernet.

Is the software free?

Yes. Control Center and Data Center are free downloads and run on Windows, Linux and macOS. Promira capabilities are unlocked by purchasing applications for the platform.

Which Beagle should I use for USB?

Use the Beagle USB 12 for low and full speed, the Beagle USB 480 for high speed, the Beagle USB 480 Power Ultimate if you also need VBUS current and voltage, and the Beagle USB 5000 v2 Ultimate for USB 3.0 SuperSpeed.

Can I script the hardware from my own software?

Yes. Total Phase provides a royalty-free API for its adapters and analysers, with language support that varies by product (for example C, Python, Visual Basic and C# for the Promira). See the product page for your model.

Can the Komodo CAN Duo monitor and transmit at the same time?

Yes. The Komodo CAN Duo has two independently isolated channels, so one can transmit while the other monitors, at up to 1 Mbps per channel.
