Exerciser/analyser handles nonstandard
interfaces
SPI Xpress provides very fast signal analysis for debug, analysis, programming and testing of chips and electronic boards that use SPI for chip-to-chip communications.
SPI Xpress is a high-speed SPI (serial peripheral interface) exerciser/analyser for debug, analysis and testing of chips and electronic boards It works for standard SPI-protocol interfaces as well as serial interfaces that vary from the SPI standard, including three-wire interfaces with a bidirectional data line and up to a 50Mbit/s datarate

SPI Xpress is delivered with 8PI Control Panel control software, which features an SPI application with a graphical user interface, an integrated waveform viewer, a scripting TCL/tk interface and direct C/C++ DLL access.
Powered either from the USB bus or from an external power supply, SPI Xpress is a versatile three and four-wire SPI exerciser/analyser which uses a USB 2.0 high-speed interface.
This permits very fast signal analysis for debug, analysis, programming and testing of chips and electronic boards that use SPI for chip-to-chip communications.
SPI Xpress can act as both a PC-controlled master (exerciser) with up to five slaves and as a SPI protocol sniffer (analyser).
Not all serial ICs use a strictly SPI-compliant interface: signal polarities and transitions can differ from the standard and there is an increasing tendency to reduce the pin count from four to three wires.
At datarates up to 50Mbit/s, SPI Xpress offers cycle-accurate operation and zero latency between accesses in a convenient tool for the electronic engineer performing design, debug and test.
SPI Xpress is supplied with accessories and control software, including a graphical user interface, a waveform viewer, scripting TCL/tk interface and direct C/C++ DLL access.
This enables complex automated control and advanced integration within custom environments developed in TCL/tk, C/C++ and Visual Basic.
Target applications include both in-lab development and on-site, after-installation servicing for: chip-to-chip communication emulation, SPI-based Flash memory access, SPI system development and debug, custom three and four-wire serial protocol communication, RF chip characterisation and test via DigRF protocol, and SPI sniffing.
