USB-based analyzer
SPI Xpress is a high-speed SPI (serial peripheral interface) exerciser/analyzer for debug, analysis, programming, and testing of chips and electronic boards from Saelig. The tool works on various serial interfaces, including three-wire with bidirectional data line, all at up to 50 Mbit/s data rate for cycle-accurate operation and zero latency between accesses. 8PI control panel software features an SPI application with graphical user interface, integrated waveform viewer, scripting TCL/tk interface, and direct C/C++ DLL access to enable automated control and integration within custom environments. Powered either from a USB bus or from an external power supply, the versatile SPI Xpress three- and four-wire analyzer uses a 2.0 USB high-speed interface to analyze for chip-to-chip communications. Suitable applications include both in-lab development and on-site servicing.
