Stratix II Hot-Socketing Specifications

Stratix II Device Handbook, Volume 1
Devices Can Be Driven Before Power-Up
You can drive signals into the I/O pins, dedicated input pins and
dedicated clock pins of Stratix II devices before or during power-up or
power-down without damaging the device. Stratix II devices support any
power-up or power-down sequence (V
to simplify system level design.
I/O Pins Remain Tri-Stated During Power-Up
A device that does not support hot-socketing may interrupt system
operation or cause contention by driving out before or during power-up.
In a hot socketing situation, Stratix II device's output buffers are turned
off during system power-up or power-down. Stratix II device also does
not drive out until the device is configured and has attained proper
operating conditions.
Signal Pins Do Not Drive the V
Supplies
Devices that do not support hot-socketing can short power supplies
together when powered-up through the device signal pins. This irregular
power-up can damage both the driving and driven devices and can
disrupt card power-up.
Stratix II devices do not have a current path from I/O pins, dedicated
input pins, or dedicated clock pins to the V
before or during power-up. A Stratix II device may be inserted into (or
removed from) a powered-up system board without damaging or
interfering with system-board operation. When hot-socketing, Stratix II
devices may have a minimal effect on the signal integrity of the
backplane.

less.
You can power up or power down the V
pins in any sequence. The power supply ramp rates can range
from 100 μs to 100 ms. All V
within 100 ms of each other to prevent I/O pins from driving
out. During hot socketing, the I/O pin capacitance is less than 15
pF and the clock pin capacitance is less than 20 pF. Stratix II
devices meet the following hot socketing specification.
