Configuration

Notes to
(1) Connect the pull-up resistors to the V
(2) The nCEO pin is left unconnected or used as a user I/O pin when it does not feed the nCE pin of another device.
(3) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL[3..0], refer to
(4) AP configuration ignores the WAIT signal during configuration mode. However, if you are accessing flash during user mode with user logic, you

memory to the Cyclone IV E device pins.
In a single-device AP configuration, the maximum board loading and board trace
length between supported parallel flash and Cyclone IV E devices must follow the
recommendations listed in
If you use the AP configuration scheme for Cyclone IV E devices, the V
banks 1, 6, 7, and 8 must be 3.3, 3.0, 2.5, or 1.8 V. Altera does not recommend using the
level shifter between the Numonyx P30 or P33 flash and the Cyclone IV E device in
the AP configuration scheme.
There are no series resistors required in AP configuration mode for Cyclone IV E
devices when using the Numonyx flash at 2.5-, 3.0-, and 3.3-V I/O standard. The
output buffer of the Numonyx P30 IBIS model does not overshoot above 4.1 V. Thus,
series resistors are not required for the 2.5-, 3.0-, and 3.3-V AP configuration option.
However, if there are any other devices sharing the same flash I/Os with Cyclone IV E
devices, all shared pins are still subject to the 4.1-V limit and may require series
resistors.
