Power-Up/Down and Hot Swapping
SX-A I/Os are configured to be hot-swappable, with the
exception of 3.3 V PCI. During power-up/down (or partial
up/down), all I/Os are tristated. VCCA and VCCI do not
have to be stable during power-up/down, and can be
powered up/down in any order. When the SX-A device is
plugged into an electrically active system, the device will
not degrade the reliability of or cause damage to the
host system. The device’s output pins are driven to a high
impedance state until normal chip operating conditions
are reached. Table 1-4 summarizes the VCCA voltage at
which the I/Os behave according to the user’s design for
an SX-A device at room temperature for various ramp-up
rates. The data reported assumes a linear ramp-up
profile to 2.5 V. For more information on power-up and
hot-swapping, refer to the application note, Actel SX-A
and RT54SX-S Devices in Hot-Swap and Cold-Sparing
Applications.

Output Buffer
“Hot-Swap” Capability (3.3 V PCI is not hot swappable)
I/O on an unpowered device does not sink current
Can be used for “cold-sparing”
Selectable on an individual I/O basis
Individually selectable slew rate; high slew or low slew (The default is high slew rate).
The slew is only affected on the falling edge of an output. Rising edges of outputs are
not affected.
Power-Up
Individually selectable pull-ups and pull-downs during power-up (default is to power-up
in tristate)
Enables deterministic power-up of device
VCCA and VCCI can be powered in any order
