Serial Configuration Devices (EPCS1, EPCS4, EPCS16 & EPCS64) Data Sheet
Table 4–3 lists the serial configuration device used with each Cyclone II
FPGA and the configuration file size. Cyclone II devices can be used with
all serial configuration devices.

Notes to Table 4–3:
(1) These are preliminary, uncompressed file sizes.
(2) This is with the Cyclone II compression feature enabled.
Table 4–4 lists the serial configuration device used with each Cyclone
FPGA and the configuration file size. Cyclone devices can only be used
with EPCS1, EPCS4, or EPCS16 devices.

Notes to Table 4–4:
(1) These are preliminary, uncompressed file sizes.
(2) This is with the Cyclone compression feature enabled.
With the new data-decompression feature in the Stratix II and Cyclone
FPGA families, designers can use smaller serial configuration devices to
configure larger FPGAs.
