Credit where it is due. The Cheetah is a proven, purpose-built high-speed SPI adapter, and it is fast. But that is all it does. Pulsar matches its SPI headroom and then covers every other bus on your board, with one app, Mission Control 3, that handles transactions and memory programming instead of the separate tools you juggle for the Cheetah.

// memory programming
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.

macOS included.
Runs natively on Windows, macOS, and Linux. Flash Center is Windows and Linux only, so Mac users are stuck in a VM.

// and there's more
Pulsar goes beyond one protocol.
You keep the high-speed SPI the Cheetah is known for. The Cheetah stops there. Pulsar keeps going, so the next board that needs another bus does not cost you another tool.
// 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.
How can I elegantly connect a Pulsar to a header designed for the Cheetah?
Every Pulsar includes an adapter to enable it to directly interface with connectors designed for the Cheetah's harness.
Is the Binho Pulsar a good upgrade from the Total Phase Cheetah?
Yes. The Pulsar keeps the high-speed SPI you bought the Cheetah for, a 50 MHz SPI controller with four chip-selects and all four modes over USB 2.0 High Speed, then adds every bus the Cheetah can't touch: I²C, UART, RS-485, GPIO, CAN-FD, and 1-Wire. All in a machined-aluminum enclosure with one modern, cross-platform app.
Does the Pulsar do high-speed SPI like the Cheetah?
Yes. Pulsar is an SPI controller to 50 MHz with up to four chip-selects and all four SPI modes, over the same USB 2.0 High Speed link, so you keep the SPI performance the Cheetah is known for.
Can the Pulsar program SPI flash like the Cheetah?
Yes. Mission Control 3's Memory Programmer reads, writes, verifies, and blank-checks SPI flash (and I²C EEPROMs) with a visual hex editor, on Windows, macOS, and Linux. Total Phase's Flash Center is Windows and Linux only.
What does the Pulsar add beyond SPI?
I²C, UART, RS-485, and six dedicated GPIO, plus CAN-FD and 1-Wire, and a programmable 1.2 to 3.3 V DUT-power rail. The Cheetah speaks SPI and nothing else.
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.
Explore the Binho Supernova How do I control it?
The Mission Control 3 desktop app (Windows, macOS, Linux) gives you a full GUI with no code, plus Python, Java, and C/C++/C# SDKs for automated test. Nothing to license.
Move past the Cheetah.
Keep the high-speed SPI. Add every other bus, sturdier on the bench, ready for whatever your next board needs.
