FPGA I/O Banks 2 and 3
IC10B2 represents the connections to I/O Bank 2 on the FPGA. Some of the I/O Bank 2
connections are used for FPGA configuration and are listed as IC10MISC.
IC10B3 represents the connections to I/O Bank 3 on the FPGA. Bank 3 is dedicated to the
DDR SDRAM interface and is consequently powered by 2.5V. See
Chapter 13, “DDR
SDRAM,” for additional information.
