Fast Passive Parallel Configuration
FPP Configuration Using a Microprocessor
In the FPP configuration scheme, a microprocessor can control the
transfer of configuration data from a storage device, such as flash
memory, to the target Stratix II or Stratix II GX device.
1 All information in “FPP Configuration Using a MAX II Device
as an External Host” on page 7–15 is also applicable when using
a microprocessor as an external host. Refer to that section for all
configuration and timing information.

FPP Configuration Using an Enhanced Configuration Device
In the FPP configuration scheme, an enhanced configuration device sends
a byte of configuration data every DCLK cycle to the Stratix II or
Stratix II GX device. Configuration data is stored in the configuration
device.
1
When configuring your Stratix II or Stratix II GX device using
FPP mode and an enhanced configuration device, the enhanced
configuration device decompression feature is available while
the Stratix II and Stratix II GX decompression and design
security features are not.
Figure 7–8 shows the configuration interface connections between a
Stratix II or Stratix II GX device and the enhanced configuration device
for single device configuration.

The figures in this chapter only show the configuration-related
pins and the configuration pin connections between the
configuration device and the device.
For more information on the enhanced configuration device and flash
interface pins, such as PGM[2..0], EXCLK, PORSEL, A[20..0], and
DQ[15..0], refer to the Enhanced Configuration Devices (EPC4, EPC8 &
EPC16) Data Sheet in volume 2 of the Configuration Handbook.
