Connect V
The nINIT_CONF pin is available on enhanced configuration devices and has an internal pull-up resistor that is
always active. This means an external pull-up resistor is not required on the nINIT_CONF/nCONFIG line. The
nINIT_CONF pin does not need to be connected if its functionality is not used. If nINIT_CONF is not used, nCONFIG
must be pulled to V
The enhanced configuration devices’ OE and nCS pins have internal programmable pull-up resistors. If internal
pull-up resistors are used, external pull-up resistors should not be used on these pins. The internal pull-up resistors
are used by default in the Quartus II software. To turn off the internal pull-up resistors, check the Disable nCS and
OE pull-ups on configuration device option when generating programming files.
For PORSEL, PGM[], and EXCLK pin connections, refer to
In the 100-pin PQFP package, you must externally connect the following pins: C-A0 to F-A0, C-A1 to F-A1, C-A15
to F-A15, C-A16 to F-A16, and BYTE# to V
100-pin PQFP and 88-pin Ultra FineLine BGA packages: C-RP# to F-RP#, C-WE# to F-WE#, TM1 to V
GND, and WP# to V
Connect the FPGA MSEL[] input pins to select the PS configuration mode. For details, refer to the appropriate
FPGA family chapter in the Configuration Handbook.
