SRAM configuration elements allow Cyclone II devices to be
reconfigured in-circuit by loading new configuration data into the device.
With real-time reconfiguration, the device is forced into command mode
with the nCONFIG pin. The configuration process loads different
configuration data, reinitializes the device, and resumes user-mode
operation. You can perform in-field upgrades by distributing new
configuration files within the system or remotely.
A built-in weak pull-up resistor pulls all user I/O pins to V
and during device configuration.
The configuration pins support 1.5-V/1.8-V or 2.5-V/3.3-V I/O
standards. The voltage level of the configuration output pins is
determined by the V
V
3.3-V compatible.
You can load the configuration data for a Cyclone II device with one of
three configuration schemes (see
target application. You can use a configuration device, intelligent
controller, or the JTAG port to configure a Cyclone II device. A low-cost
configuration device can automatically configure a Cyclone II device at
system power-up.
Multiple Cyclone II devices can be configured in any of the three
configuration schemes by connecting the configuration enable (nCE) and
configuration enable output (nCEO) pins on each device.

Devices chapter of the Cyclone II Handbook, Volume 2.
