Functional Description
Figure 2–2. FPP Configuration
Notes to
Figure 2–2
:
(1)
The V
CC
should be connected to the same supply voltage as the configuration device.
(2)
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
CC
either directly or through a resistor.
(3)
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
Table 2–9
.
(5)
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
CC
. Additionally, you must make the following pin connections in both
100-pin PQFP and 88-pin Ultra FineLine BGA packages:
C-RP#
to
F-RP#
,
C-WE#
to
F-WE#
,
TM1
to V
CC
,
TM0
to
GND, and
WP#
to V
CC
.
(6)
Connect the FPGA
MSEL[]
input pins to select the FPP configuration mode. For details, refer to the appropriate
FPGA family chapter in the Configuration Handbook.
Multiple FPGAs can be configured using a single enhanced configuration
device in FPP mode. In this mode, multiple Stratix series and/or APEX II
FPGAs are cascaded together in a daisy chain.
