During device configuration, Cyclone III devices read configuration data using the
parallel interface and configure their SRAM cells. This scheme is referred to as the AP
configuration scheme because the device controls the configuration interface. This
scheme contrasts with the FPP configuration scheme, where an external host controls
the interface.
AP Configuration Supported Flash Memory
The AP configuration controller in Cyclone III devices is designed to interface with
the Numonyx StrataFlash
StrataFlash Embedded Memory P33 flash family, which are two industry standard
flash families. Unlike serial configuration devices, both of the flash families supported
in the AP configuration scheme are designed to interface with microprocessors. By
configuring from an industry standard microprocessor flash which allows access to
the flash after entering user mode, the AP configuration scheme allows you to
combine configuration data and user data (microprocessor boot code) on the same
flash memory.
The Numonyx P30 and P33 flash families support a continuous synchronous burst
read mode at 40 MHz DCLK frequency for reading data from the flash. Additionally,
the Numonyx P30 and P33 flash families have identical pin-out and adopt similar
protocols for data access.
Cyclone III devices use a 40-MHz oscillator for the AP configuration scheme.

configuration scheme.
Table 9–11. Supported Commodity Flash for the AP Configuration Scheme for Cyclone III
Devices
The AP configuration scheme of Cyclone III devices supports the Numonyx P30 and
P33 family 64-, 128-, and 256-Mbit flash memories. Configuring Cyclone III devices
from the Numonyx P30 and P33 family 512-Mbit flash memory is possible, but you
must properly drive the extra address and nCS pins as required by these flash
memories.
You must refer to the respective flash data sheets to check for supported speed grades
and package options.
Notes to
(1) The AP configuration scheme only supports flash memory speed grades of 40 MHz and above.
(2) 3.3- , 3.0-, 2.5-, and 1.8-V I/O options are supported for the Numonyx P30 flash family.
(3) 3.3-, 3.0- and 2.5-V I/O options are supported for the Numonyx P33 flash family.
