Configuration Schemes
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 VCCIO before
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 VCCIO of the bank where the pins reside. The bank
VCCIO selects whether the configuration inputs are 1.5-V, 1.8-V, 2.5-V, or
3.3-V compatible.
Configuration
Schemes
You can load the configuration data for a Cyclone II device with one of
three configuration schemes (see Table 3–4), chosen on the basis of the
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.
