Maximum Allowed Overshoot or Undershoot Voltage
During transitions, input signals may overshoot to the voltage listed 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 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
4.2 V can only be at 4.2 V for 10.74% over the lifetime of the device; for device lifetime
of 10 years, this amounts to 10.74/10ths of a year.

Figure 1–1
shows the methodology to determine the overshoot duration. In the example in
Figure 1–1,
overshoot
voltage is shown in red and is present on the input pin of the Cyclone III device at over 4.1 V but below 4.2 V. From
Table 1–1,
for an overshoot of 4.1 V, the percentage of high time for the overshoot can be as high as 31.97% over
a 10-year period. Percentage of high time is calculated as ([delta T]/T) × 100. This 10-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 in which the device is in an idle state, lifetimes are increased.

CCIO

CCA
pins must be powered to 2.5 V (even when PLLs are not used), and
must be powered up and powered down at the same time.
(2) V
CCD_PLL
must always be connected to V
CCINT
through a decoupling capacitor and ferrite bead.
(3) The V
CC
must rise monotonically.
(4) All input buffers are powered by the V
CCIO
supply.
(5) POR time for Standard POR ranges between 50–200 ms. Each individual power supply should reach the recommended operating range within
50 ms.
(6) POR time for Fast POR ranges between 3–9 ms. Each individual power supply should reach the recommended operating range within 3 ms.

DC Characteristics
This section lists the I/O leakage current, pin capacitance, on-chip termination (OCT)
tolerance, and bus hold specifications for Cyclone III devices.
Supply Current
Standby current is the current the device draws after the device is configured with no
inputs or outputs toggling and no activity in the device. Use the Excel-based early
power estimator (EPE) to get the supply current estimates for your design because
these currents vary largely with the resources used.
Table 1–4
lists I/O pin leakage
current for Cyclone III devices.

I/O leakage current limit is applicable when the internal clamping diode is off. A higher current can be the
observed when the diode is on.
Bus Hold
Bus hold retains the last valid logic state after the source driving it either enters the
high impedance state or is removed. Each I/O pin has an option to enable bus hold in
user mode. Bus hold is always disabled in configuration mode.
Table 1–5
lists bus hold specifications for Cyclone III devices.
