Functional Description
serial interface that can store configuration data for a Stratix II FPGA or a
Cyclone series device and reload the data to the device upon power-up or
reconfiguration. Table 4–1 lists the serial configuration devices.

Note to Table 4–1:
(1) This information is preliminary.
You can vertically migrate from the EPCS1 to the EPCS4 device since they
are offered in the same device package. Similarly, you can vertically
migrate from the EPCS16 to the EPCS64 device.
Table 4–2 lists the serial configuration device used with each Stratix II
FPGA and the configuration file size. Stratix II devices can only be used
with EPCS16 or EPCS64 devices.
