See the technical documentation for the command interface. The 0v Ground pin must be connected to the 0v (Ground) on your device. Do not connect this to an RS232 port without using a suitable RS232 logic level adapter. These are logic level signals, not RS232. SCK is the SPI clock output from the USB-ISS, connect it to SCK on your device.ĬE is the active low chip enable signal, connect it to CE on your device. Now that the SPI flash is programmed with the target bitstream, the UltraScale FPGA configures directly from the SPI flash after a PROGRAMB assertion or power cycle if the mode pins are set for master SPI configuration mode. SDO is the SPI output from the USB-ISS, connect it to SDI on your device. to program the SPI flash with the target bitstream over the JTAG connection through the indirect programming bitstream. SDI is the SPI input to the USB-ISS, connect it to SDO on your device. These resistors are automatically disconnected in other modes. The USB-ISS module is always a bus master, and is fitted with 4.7kΩ pull-up resistors. They should be connected directly to the SCL and SDA pins on your I2C device. I/O pinsĮach I/O pin, 1 to 4, may be individually selected to be analog input or digital Input or digital output. Inputs will not accept voltage higher than the selected supply voltage, so when operating at 3.3V the inputs are not 5V tolerant. Analog inputs span from 0v to the supply votlage, and are connectedt to a 10-bit ADC. The Red LED will flash whenever there is a valid I2C or SPI command received. The Green LED is a power indicator and is on when the module is connected to a powered USB port. Do not apply your own voltage to this pin. This regulator is capable of 50mA, so when running at 3.3V approximately 30mA is available to external devices.

When the jumper is removed, a 3.3V regulator supplies the power. From a standard 100mA USB port, when operating at 5V, the USB-ISS module can supply up to 80mA to external devices. With the LEDs on, it takes approximately 20mA. Use the "power link" jumper to operate from 5V, or remove it for 3.3V
