Operating Conditions
1
Cyclone IV E industrial devices I7 are offered with extended operating temperature
range.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Cyclone IV
devices. The values are based on experiments conducted with the device and
theoretical modeling of breakdown and damage mechanisms. The functional
operation of the device is not implied at these conditions.
Table 1–1
lists the absolute
maximum ratings for Cyclone IV devices.
c
Conditions beyond those listed in
Table 1–1
cause permanent damage to the device.
Additionally, device operation at the absolute maximum ratings for extended periods
of time have adverse effects on the device.

Table 1–1:
(1) Supply voltage specifications apply to voltage readings taken at the device pins with respect to ground, not at the
power supply.
Maximum Allowed Overshoot or Undershoot Voltage
During transitions, input signals may overshoot to the voltage shown in
Table 1–2
and
undershoot to –2.0 V for a magnitude of currents less than 100 mA and for periods
shorter than 20 ns.
Table 1–2
lists the maximum allowed input overshoot voltage and
the duration of the overshoot voltage as a percentage over the lifetime of the device.
The maximum allowed overshoot duration is specified as a percentage of high-time
over the lifetime of the device.

A DC signal is equivalent to 100% duty cycle. For example, a signal that overshoots to
4.3 V can only be at 4.3 V for 65% over the lifetime of the device; for a device lifetime
of 10 years, this amounts to 65/10ths of a year.

Figure 1–1
shows the methodology to determine the overshoot duration. The
overshoot voltage is shown in red and is present on the input pin of the Cyclone IV
device at over 4.3 V but below 4.4 V. From
Table 1–2,
for an overshoot of 4.3 V, the
percentage of high time for the overshoot can be as high as 65% over a 10-year period.
Percentage of high time is calculated as ([delta T]/T) × 100. This 10-year period
assumes that the device is always turned on with 100% I/O toggle rate and 50% duty
cycle signal. For lower I/O toggle rates and situations in which the device is in an idle
state, lifetimes are increased.
