This chapter contains complete information on the Stratix
configuration schemes, how to execute the required configuration
schemes, and all the necessary option pin settings.
Stratix III devices use SRAM cells to store configuration data. As SRAM
memory is volatile, you must download configuration data to the
Stratix III device each time the device powers up. You can configure
Stratix III devices using one of four configuration schemes:

All configuration schemes use either an external controller (for example,
a MAX
download cable. Refer to the
more information.
Configuration Devices
The Altera serial configuration devices (EPCS128, EPCS64, and EPCS16)
support a single-device and multi-device configuration solution for
Stratix III devices and are used in the fast AS configuration scheme. Serial
configuration devices offer a low-cost, low-pin count configuration
solution.
For information on serial configuration devices, refer to the
Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128)
Data Sheet
All minimum timing information in this handbook covers the entire
Stratix III family. Some devices may work at less than the minimum
timing stated in this handbook due to process variation.
Configuration Schemes
Select the configuration scheme by driving the Stratix III device MSEL
pins either high or low, as shown in
