Detailed Description
1. Spartan-6 XC6SLX16-2CSG324 FPGA
A Xilinx Spartan-6 XC6SLX16-2CSG324 FPGA is installed on the Embedded Development
Board.
Configuration
The SP601 supports configuration in the following modes:
• Master SPI x4
• Master SPI x4 with off-board device
• BPI
• JTAG (using the included USB-A to Mini-B cable)
For details on configuring the FPGA, see “Configuration Options.”
I/O Voltage Rails
There are four available banks on the LX16-CS324 device. Banks 0, 1, and 2 are connected
for 2.5V I/O. Bank 3 is used for the 1.8V DDR2 component memory interface of Spartan-6
FPGA’s hard memory controller. The voltage applied to the FPGA I/O banks used by the
SP601 board is summarized in Table 1-2.
