FMC Expansion Connector #1
Samtec ASP-134603-01. The FMC expansion connector #1 (J13) follows the VITA 57.1
FMC standard and is used in low pin count (LPC) format. It can either be used to
accommodate a single width FMC Module or one dual FMC Module when used in
conjuncture with FMC expansion connector #2 (J19). See FMC expansion connector for
details. To use the Flash and ZBT memories, the memory enable pin needs to be set in
the FPGA (see
Table 1-6
).
Table 1-9
defines the FMC Expansion Connector #1 pin
assignments.
Note
: The Flash memory and ZBT synchronous SRAM cannot be used when using
FMC module #1. The FMC connector #1 has its own adjustable power supply to
provide the appropriate voltage to the FPGA bank used to communicate with the FMC
module. Be sure that the FMC adjustable power supply is configured for the voltage
specified by the FMC module. See FMC expansion connector for instructions about
how to configure the adjustable power supplies.
