ISLKU060DEMO1Z Reference Manual
1. Functional Description
The ISLKU060DEMO1Z development platform allows users to prototype and evaluate the performance of the
FPGA in different applications. Figure 1 shows a block diagram of the development board. The board includes 4x
4GB Double Data Rate 3 (DDR3) memory and 2x 256MB SPI flash memory, a Gigabit Ethernet (GbE) port, RS-
485 communication port and a JTAG header for programming. On-board DC/DC Point-of-Load (PoL) Converters
power the FPGA and peripherals from a 5V power supply input.
1.1 Getting Started
1. Power Switch SW1 switches power to the ISLKU060DEMO1Z. Before making connections, ensure it is in the
down (OFF) position.
2. Apply +5VDC to the banana connectors J5 and J6. J5 is positive terminal and J6 is GND.
3. Move SW1 to the up (ON) position to power on board.
4. The LED indicators in the upper right sequence on to indicate power sequencing to the FPGA.
5. When the FPGA is properly powered and configured successfully, the FPGA_PROG_B, FPGA_INIT_B and
FPGA_DONE LEDs in the lower left hand corner of the board illuminate green.
6. Visit the Xilinx Kintex Ultrascale website to download the Vivado Design Suite and get started on your design.
1.2 Kintex XQRKU060 Power Solution
Table 1 summarizes the Renesas part numbers, descriptions and operation conditions of the various DC-DC
converters used in the space grade design.
In addition to the power management ICs in Table 1, two ISL70321SEH quad power supply sequencers and an
ISL70062SEH NMOS load switch control the power-up and power-down sequences of the eight power supply
rails. An ISL70244SEH Radiation Hardened Op-Amp is also used for buffering the VREF of the DDR3 VTT supply.

1. A mechanical potentiometer, labeled R4781, is available to tune the VCC Core voltage across a range of 0.95V to 0.98V. This feature
allows adjusting to a specific core voltage as determined by the Xilinx Power Estimator (XPE) tool when configuring the Kintex
XQRKU060.
