Electrical Characteristics
Operating Conditions
When Stratix?III devices are implemented in a system, they are rated according to a set of defined parameters. To maintain the highest possible performance and reliability of StratixIII devices, system designers must consider the operating requirements discussed in this chapter. StratixIII devices are offered in both
commercial and industrial grades. Commercial devices are offered in –2 (fastest), –3, –4 and –4L speed grades. Industrial devices are offered only in –3, –4, and –4L speedgrades.
1
In this chapter, a prefix associated with the operating temperature range is attached to the speed grades; commercial with “C” prefix and industrial with “I” prefix.
Commercial devices are therefore indicated as C2, C3, C4, and C4L per respective speed grades. Industrial devices are indicated as I3, I4, and I4L.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for StratixIII 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. Conditions beyond those listed in Table1–1 may cause permanent damage to the device. Additionally, device operation at the absolute maximum ratings for extended periods may have adverse effects on the device.

Maximum Allowed Overshoot/Undershoot Voltage
During transitions, input signals may overshoot to the voltage shown in Table1–2 and undershoot to -2.0V for input currents less than 100mA and periods shorter than 20ns.
Table1–2 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 percentage of high-time over the lifetime of the device.
A DC signal is equivalent to 100 % duty cycle. For example, a signal that overshoot to 4.2 V can only be at 4.2 V for 15.8 % over the lifetime of the device; for device lifetime of 10 years, this amounts to 15.8/10ths of a year. Figure1–1 shows the way to determine the overshoot duration.Figure1–1.Overshoot Duration
4.1 V3.15 V3.0 VΔTT1
Figure1–1 shows the methodology to determine the overshoot duration. In the
example shown in Figure1–1, the overshoot voltage is shown in red and is present at the StratixIII pin, up to 4.1 V. From Table1–2, for an overshoot of up to 4.1 V, the percentage of high time for overshoot > 3.15 V can be as high as 46% over an 11.4-year period. The percentage of high time is calculated as (delta T/T) * 100. This 11.4-year period assumes 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 where the device is in an idle state, lifetimes are increased.

Refer to the figures for “Differential I/O Standards” in “Glossary” for receiver input and transmitter output waveforms, and for all differential I/O standards (LVDS, mini-LVDS, RSDS). VCC_CLKIN is the power supply for differential column clock input pins. VCCPD is the power supply for row I/Os and all other column I/Os.
