8.9 FMC memory extension connectors CN12 and CN13
All signals for memory are also connected to memory connectors CN12 and CN13 for memory daughterboards.
Two 40-pin male headers CN12 and CN13 are used to connect with the memory daughterboard. GPIOs which
work as FMC memory signals and don’t on CN5 and CN6 are available on these two connectors.
The space between these two connectors is defined as a standard that allows developing common
daughterboards. The standard width between CN13 pin1 and CN12 pin1 is 1914 mils (48.62 mm). For signal
assignment details refer to
Table 62 , Table 63 , Table 64 , and Table 65 .
