XC2C64A CoolRunner-II CPLD
IC18 is a Xilinx XC2C64A CoolRunner-II CPLD. The CPLD primarily provides additional
flexibility when configuring the FPGA from parallel NOR Flash and during MultiBoot
configurations.
When the CPLD is loaded with the appropriate design, JP10 enables a watchdog timer in
the CPLD used during fail-safe MultiBoot configurations.
See Chapter 16, “XC2C64A CoolRunner-II CPLD,” for more information.
