Benefits

Used as a SPI master, this Xpress series device lets you play the role of a bus master from the host PC.

As a SPI analyzer, it lets you sample the serial protocol traffic for checking and analysis.

1.       50 MHz max SCLK frequency

2.       25 MHz max sampling frequency in analyzer mode

3.       Up to 5 slaves

4.       Zero-latency between accesses

5.       Support of all modes (data toggle edge / data sampling edge selection)

Moreover, as de facto standard, SPI interface protocol is characterized by many parameters and custom variations.

SPI Xpress host adapter is fits both standard serial peripheral interface protocol and non-standard 4-wires and 3-wires serial protocol interfaces, both as a Master and an Analyzer.

As a palm-sized, PC-based and USB-powered SPI host adapter tool, it typically suits embedded system development and validations usage scenarios, when there is a need to test and debug at signal level by interacting with each component of a serially-interconnected system.

1.       Stop quitting your desk for trials in the lab

2.       Stop waiting for the bench-top logic analyzer or signal generator to be available

3.       Place your debug tool next to your laptop on any desk

4.       Perform manual bench testing on your digital system (board, FPGA, ASIC, SoC) prototype
