Figure 9–8. Single-Device AP Configuration Using Numonyx P30 and P33 Flash Memory
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) The AP configuration ignores the WAIT signal during configuration mode. However, if you are accessing flash during user mode with user logic,
Cyclone III Device Handbook, Volume 1
page
you can optionally use a normal I/O to monitor the WAIT signal from the Numonyx P30 or P33 flash.

Numonyx P30/P33 Flash
The interface for the Numonyx P30 flash memory and P33 flash memory connects to
Cyclone III device pins, as shown in
In a single-device AP configuration, the maximum board loading and board trace
length between the supported parallel flash and Cyclone III devices must follow the
recommendations listed in
If you use the AP configuration scheme for Cyclone III devices, the V
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/P33 flash and the Cyclone III device in the AP
configuration scheme.
There are no series resistors required in the AP configuration mode for Cyclone III
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 III
devices, all shared pins are still subject to the 4.1-V limit and may require series
resistors.
