Configuration Features
Configuration File Size
Table 9–3 lists the approximate uncompressed configuration file sizes for Cyclone III
device family. To calculate the amount of storage space required for multiple device
configurations, add the file size of each device together.

Use the data in Table 9–3 only to estimate the file size before design compilation.
Different configuration file formats, such as Hexadecimal (.hex) or Tabular Text
File (.ttf) formats, have different file sizes. However, for any specific version of the
Quartus II software, any design targeted for the same device has the same
uncompressed configuration file size. If you are using compression, the file size varies
after each compilation because the compression ratio is design dependent.
f For more information about setting device configuration options or creating
configuration files, refer to the Software Settings section in volume 2 of the
Configuration Handbook.
Configuration and JTAG Pin I/O Requirements
Cyclone III devices are manufactured using the TSMC 65-nm low-k dielectric process;
Cyclone III LS devices are manufactured using the TSMC 60-nm low-k dielectric
process. Although Cyclone III device family uses TSMC 2.5-V transistor technology in
the I/O buffers, the devices are compatible and able to interface with 2.5-, 3.0-, 3.3-V
configuration voltage standards. However, you must follow specific requirements
when interfacing Cyclone III device family with 2.5-, 3.0-, 3.3-V configuration voltage
standards.
