Fast Active Serial Configuration (Serial Configuration Devices)
FPP Configuration Using a Microprocessor
In this configuration scheme, a microprocessor can control the transfer of
configuration data from a storage device, such as flash memory, to the target
Stratix IV device.
All information in “FPP Configuration Using a MAX II Device as an External Host”
on page 10–6 is also applicable when using a microprocessor as an external host. Refer
to this section for all configuration and timing information.
Fast Active Serial Configuration (Serial Configuration Devices)
In the fast AS configuration scheme, Stratix IV devices are configured using a serial
configuration device. These configuration devices are low-cost devices with
non-volatile memory that feature a simple four-pin interface and a small form factor.
The largest serial configuration device currently supports 128 MBits of configuration
bitstream. Use the Stratix IV decompression features or select an FPP or PS
configuration scheme for EP4SE360, EP4SGX290, EP4S40G5, EP4S100G3 and larger
devices.
f For more information about serial configuration devices, refer to the Serial
Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Data Sheet
chapter in volume 2 of the Configuration Handbook.
Serial configuration devices provide a serial interface to access configuration data.
During device configuration, Stratix IV devices read configuration data using the
serial interface, decompress data if necessary, and configure their SRAM cells. This
scheme is referred to as the AS configuration scheme because the Stratix IV device
controls the configuration interface. This scheme contrasts with the PS configuration
scheme where the configuration device controls the interface.
1 The Stratix IV decompression and design security features are fully available when
configuring your Stratix IV device using fast AS mode.
