* Promira I²C, SPI, and eSPI each require a separately-purchased Total Phase Application license. No Total Phase adapter supports MIPI I3C.
Credit where it is due. Each Total Phase adapter has a place. The Aardvark ships an I²C/SPI target (peripheral) mode that the Pulsar, a controller, does not, and the Promira is a higher-ceiling platform for 80 MHz SPI, 3.4 MHz I²C, sub-1.2 V signaling, and bus analysis. If you specifically need those, reach for them. For everyday multi-protocol host-adapter work, though, the Pulsar covers it in one modern tool, with free cross-platform software and every protocol included.

Program EEPROM and SPI FLASH memories with ease.
Reading and writing I²C EEPROMs and SPI flash is one of the top use-cases for host adapters. Mission Control 3’s Memory Programmer does it with a visual hex editor, per-chip presets, read / write / verify / blank-check / erase, and binary file load and save, then goes places Total Phase’s Flash Center can’t.

// mipi i3c
Need MIPI I3C? Binho can help.
No Total Phase adapter, not the Aardvark, Cheetah, or Promira, speaks MIPI I3C. The Binho Supernova does, adding I3C alongside I²C, SPI, UART, and GPIO, on the very same Mission Control 3 software as the Pulsar.
And I3C is our specialty, not an afterthought. As the industry begins migrating NVMe-MI / MCTP over I3C, Binho tools accelerate your development rather than the legacy tools that will slow it down.
// ai native
Ready for your agents.
An open, fully documented SDK lets an AI agent drive real silicon over I2C, SPI, UART, RS-485, and CAN-FD, learning the whole API from a single prompt. It is the kind of modern workflow a legacy adapter was never built for.
// the prompt
Use the Pulsar to scan the I2C bus, read the EEPROM at 0x50, and tell me what is stored there.
One sentence in. The agent learns the API, runs it on real silicon, and reports back.

Common questions.
Is the Binho Pulsar a good alternative to Total Phase adapters?
Yes. The Pulsar is a modern multi-protocol host adapter that covers the I²C and SPI work you rely on Total Phase for, over a 480 Mbps USB 2.0 High Speed link, and adds UART, RS-485, GPIO, CAN-FD, and 1-Wire. It ships in a machined-aluminum enclosure with free, cross-platform Mission Control 3 software, and every protocol is included with no per-protocol licenses.
Which Total Phase product does the Pulsar replace?
The Pulsar is a strong alternative to the Aardvark (I²C/SPI), the Cheetah (high-speed SPI), and the Promira Serial Platform (licensed I²C/SPI). Pick the head-to-head comparison above that matches the device you are replacing for a detailed breakdown.
Do I have to buy licenses to unlock protocols on the Pulsar?
No. Where the Total Phase Promira gates I²C and SPI behind separately-purchased Application licenses, the Pulsar includes every protocol out of the box. Mission Control 3 is free for Windows, macOS, and Linux, with a no-code GUI, a memory programmer, and Python, Java, and C/C++/C# SDKs. Nothing is behind a license or subscription.
What do the Total Phase adapters do that the Pulsar does not?
A few things worth knowing. The Aardvark ships an I²C/SPI target (peripheral) mode that the Pulsar, a controller, does not. The Promira is a higher-ceiling platform: with licenses it reaches 80 MHz SPI and 3.4 MHz I²C, signals down to 0.9 V, and can sniff and analyze buses. If you specifically need target emulation, bus analysis, or those top speeds, those tools are built for it. For everyday multi-protocol host-adapter work, Pulsar covers it for less.
Does the Pulsar support MIPI I3C?
No. The Pulsar covers SPI, I²C, UART, and RS-485, but not I3C. If you need MIPI I3C, reach for the Binho Supernova: it adds I3C alongside I²C, SPI, UART, and GPIO, and runs on the very same Mission Control 3 software and SDKs as the Pulsar, so moving between them is seamless.
