SPI StormData sheet2.2 Minimum Host PC requirementsSPI Storm connects to any PC using Microsoft Windows XP or Windows 7 operating systems (32-bit/64bit) through a USB 2.0 port connector.NET 4.0 or .NET 4.0 (or a more recent version) client profile framework must be installed – .aspx?FamilyID e5ad0459-cbcc-4b4f-97b6fb17111cf5442.3 Operating powerThe main power supply of the SPI Storm device is taken from the USB bus to provide the necessaryvoltage to the device core. By default, the I/O voltage standard is 3.3V LVCMOS.To use a different voltage standard for the I/O, the jumper located on the I/O external voltage supplyconnector must be removed and an external voltage source must be applied on this connector. Externalvoltage level must be between 1.25V and 3.3V.The external power supply connector is located at the side of the device. It is protected with a jumper.This power connector is labelled “GND VEXT”. ! Respect the connector polarity !Figure 2:System connector external power supply pinsVEXT connector locationGND pinVEXT (positive voltage) pin2.4 USB and system interface connectionsA USB mini-B to USB type A cable is provided with the SPI Storm device.A set of 34 flying lead wires connect the SPI Storm device to the board under test. A standard pinheader with 2.54 mm (0.1 inch) pitch must be foreseen on the target board where access is desired.Revision 1.02 - February 2015www.byteparadigm.com5/9
