Configuration Handbook, Volume 2
If the external flash interface feature is not used, then the flash pins should be left unconnected since they are
internally connected to controller unit. The only pins that need external connections are WP#, WE#, and RP#. If the
flash is being used as an external memory source, then the flash pins should be connected as outlined in the pin
descriptions section.
F-RP# and F-WE# are pins on the flash die. C-RP# and C-WE# are pins on the controller die. C-WE# and F-WE#
should be connected together on the PCB. F-RP# and C-RP# should also be connected together on the PCB.
WP# (write protection pin) should be connected to a high level (3.3 V) to be able to program the flash bottom boot
block, which is required when programming the device using the Quartus II software.

Package Layout Recommendation
EPC16 and EPC8 enhanced configuration devices in the 100-pin PQFP
packages have different package dimensions than other Altera 100-pin
PQFP devices (including EPC4).
footprint specifications for enhanced configuration devices that allows
for vertical migration between all three devices. These footprint
dimensions are based on vendor-supplied package outline diagrams.
