for the AP configuration scheme.
AP configuration of Cyclone III devices supports the Intel P30 family 64
Mbit, 128 Mbit and 256 Mbit flash memories. Configuring Cyclone III
devices from the Intel P30 family 512 Mbit and 1 Gbit flash memories are
possible, but you need to properly drive the extra address and chip select
pins as required by these flash memories.

In addition, AP configuration of Cyclone III devices supports the
128 Mbit and 256 Mbit flash memories of the Spansion S29WS-N family.
The Spansion S29WS-N family supports the 80 MHz (0S part identifier),
66 MHz (0P part identifier) and 54 MHz (0L part identifier) speed grades.
The AP configuration scheme in Cyclone III devices supports all three
speed grades. However, AP configuration for all three speed grades
should be capped at 40 MHz. The advantage of the faster speed grades is
realized when your design in the Cyclone III devices access the flash
memory in user mode.

Schemes
Flash Memory Density
The AP configuration scheme only support flash memory speed grades of
40 MHz and above. Therefore, you must refer to the respective flash datasheets to
check for the supported speed grades and package options.
For information on the operation of the StrataFlash Embedded Memory (P30)
flash memories from Intel, search for the key word P30 on the Intel web site at
www.intel.com to obtain the P30 family datasheet.
For information on the operation of the S29WSxxxN MirrorBit flash memories
from Spansion, search for the key word S29WS-N on the Spansion web site at
www.spansion.com to obtain the S29WS-N family datasheet.
Both 3.3 V and 1.8 V I/O options are supported for Intel P30 flash family.
Only 1.8 V I/O option is supported for Spansion S29WS-N flash family.

You must refer to the respective flash datasheets to check for the
supported speed grades and package options. For example, the
Intel P30 family only has a single speed grade at 40MHz.
However, it does not support 40 MHz on the TSOP packages.
Therefore, the P30 FBGA packages is supported for the AP
configuration scheme, and the TSOP packages is not supported.
