Operating Modes
The Stratix II architecture uses SRAM configuration elements that require
configuration data to be loaded each time the circuit powers up. The
process of physically loading the SRAM data into the device is called
configuration. During initialization, which occurs immediately after
configuration, the device resets registers, enables I/O pins, and begins to
operate as a logic device. The I/O pins are tri-stated during power-up,
and before and during configuration. Together, the configuration and
initialization processes are called command mode. Normal device
operation is called user mode.
SRAM configuration elements allow Stratix 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 a
device 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 either
within the system or remotely.
PORSEL is a dedicated input pin used to select POR delay times of 12 ms
or 100 ms during power-up. When the PORSEL pin is connected to
ground, the POR time is 100 ms; when the PORSEL pin is connected to
V
The nIO PULLUP pin is a dedicated input that chooses whether the
internal pull-ups on the user I/O pins and dual-purpose configuration
I/O pins (nCSO, ASDO, DATA[7..0], nWS, nRS, RDYnBSY, nCS, CS,
RUnLU, PGM[2..0], CLKUSR, INIT_DONE, DEV_OE, DEV_CLR) are on or
off before and during configuration. A logic high (1.5, 1.8, 2.5, 3.3 V) turns
off the weak internal pull-ups, while a logic low turns them on.
Stratix II devices also offer a new power supply, V
connected to 3.3 V in order to power the 3.3-V/2.5-V buffer available on
the configuration input pins and JTAG pins. V
