Fast Passive Parallel ConfigurationFPP Configuration Using a MicroprocessorIn the FPP configuration scheme, a microprocessor can control thetransfer of configuration data from a storage device, such as flashmemory, to the target Stratix II or Stratix II GX device.fAll information in “FPP Configuration Using a MAX II Device as anExternal Host” on page 7–15 is also applicable when using amicroprocessor as an external host. Refer to that section for allconfiguration and timing information.FPP Configuration Using an Enhanced Configuration DeviceIn the FPP configuration scheme, an enhanced configuration device sendsa byte of configuration data every DCLK cycle to the Stratix II orStratix II GX device. Configuration data is stored in the configurationdevice.1 When configuring your Stratix II or Stratix II GX device usingFPP mode and an enhanced configuration device, the enhancedconfiguration device decompression feature is available whilethe Stratix II and Stratix II GX decompression and designsecurity features are not.Figure 7–8 shows the configuration interface connections between aStratix II or Stratix II GX device and the enhanced configuration devicefor single device configuration.1 The figures in this chapter only show the configuration-relatedpins and the configuration pin connections between theconfiguration device and the device.fFor more information on the enhanced configuration device and flashinterface pins, such as PGM[2..0], EXCLK, PORSEL, A[20..0], andDQ[15..0], refer to the Enhanced Configuration Devices (EPC4, EPC8 &EPC16) Data Sheet.7–26 Altera CorporationStratix II Device Handbook, Volume 2 May 2007
