Description
The Cheetah SPI Host Adapter is a high speed SPI adapter. It enables communication via the SPI bus with up to 40+ MHz and is the ideal tool for developing, testing and programming SPI-based systems.
SPI Features
- Works in master or slave mode.
- Master signaling rate of up to 8 Mbit / s.
- Slave signaling rate of up to 4 Mbit/s.
- Send/receive full-duplex master.
- Asynchronous slave send / receive.
- Software-configurable target power pins to power downstream devices.
- Software-configurable slave select (SS) polarity in master mode.

High Speed USB 2.0
The Cheetah adapter is a bus-powered, high-speed USB 2.0 device.
All data captured by the Cheetah adapter is sent at 480 Mbps to the Transfer test computer.
As a bus-powered device, the Cheetah adapter does not require a power supply, making it the ideal tool for engineers.
Available software
Control Center Software
The Control Center allows users to fully utilize the functions of I2C, SPI and GPIO immediately. Multiple devices can be used simultaneously and a virtually unlimited number of configurations can be selected, allowing engineers to develop and test their embedded systems.
Flash Center Software
Total Phase Flash Center Software is a software package that allows engineers to quickly erase, program and verify I2C and SPI-based EEPROM and Flash memory chips. In addition, non-listed building blocks can be added within minutes via the XML-based library.
Labview Driver
The Cheetah LabVIEW driver is a free, open-source LabVIEW instrument driver for accessing the Cheetah SPI host adapter within the LabVIEW development environment. The driver package is Windows oriented and based on the Cheetah software library.
