This chapter describes the electric characteristics, switching characteristics, and I/O
timing for Cyclone® III devices. A glossary is also included for your reference.
Electrical Characteristics
The following sections provide information about the absolute maximum ratings,
recommended operating conditions, DC characteristics, and other specifications for
Cyclone III devices.
Operating Conditions
When Cyclone 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 Cyclone III devices, system designers must consider the operating
requirements in this document. Cyclone III devices are offered in commercial,
industrial, and automotive grades. Commercial devices are offered in –6 (fastest), –7,
and –8 speed grades. Industrial and automotive devices are offered only in –7 speed
grade.
1
In this chapter, a prefix associated with the operating temperature range is attached to
the speed grades; commercial with “C” prefix, industrial with “I” prefix, and
automotive with “A” prefix. Commercial devices are therefore indicated as C6, C7,
and C8 per respective speed grades. Industrial and automotive devices are indicated
as I7 and A7, respectively.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Cyclone III
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 III devices.

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.

Note to Table 1–2:
(1) 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.
Figure 1–1 shows the methodology to determine the overshoot duration.

Notes to Table 1–3:
(1) VCCIO for all I/O banks must be powered up during device operation. All VCCA 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) VCCD_PLL must always be connected to VCCINT through a decoupling capacitor and ferrite bead.
(3) The VCC must rise monotonically.
(4) All input buffers are powered by the VCCIO 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.
f For more information about power estimation tools, refer to the PowerPlay Early Power
Estimator User Guide and the PowerPlay Power Analysis chapter in the Quartus II
Handbook.

Notes to Table 1–4:
(1) This value is specified for normal device operation. The value varies during device power-up. This applies for all
VCCIO settings (3.3, 3.0, 2.5, 1.8, 1.5, and 1.2 V).
(2) 10 A 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.

Example 1–1 shows you the example to calculate the change of 50 I/O impedance
from 25°C at 3.0 V to 85°C at 3.15 V:
Example 1–1.
RV = (3.15 – 3) × 1000 × –0.026 = –3.83
RT = (85 – 25) × 0.262 = 15.72
Because RV is negative,
MFV = 1 / (3.83/100 + 1) = 0.963
Because RT is positive,
MFT = 15.72/100 + 1 = 1.157
MF = 0.963 × 1.157 = 1.114
Rfinal = 50 × 1.114 = 55.71

Switching Characteristics
Power Consumption
You can use the following methods to estimate power for a design:
■
the Excel-based EPE.
■
the Quartus II PowerPlay power analyzer feature.
The interactive Excel-based EPE is used prior to designing the device to get a
magnitude estimate of the device power. The Quartus II PowerPlay power analyzer
provides better quality estimates based on the specifics of the design after place-androute is complete. The PowerPlay power analyzer can apply a combination of userentered, simulation-derived, and estimated signal activities which, combined with
detailed circuit models, can yield very accurate power estimates.
f For more information about power estimation tools, refer to the Early Power Estimator
User Guide and the PowerPlay Power Analysis chapter in volume 3 of the Quartus II
Handbook.
Switching Characteristics
This section provides the performance characteristics of the core and periphery blocks
for Cyclone III devices. All data is final and is based on actual silicon characterization
and testing. These numbers reflect the actual performance of the device under
worst-case silicon process, voltage, and junction temperature conditions.

Notes to Table 1–20:
(1) VCCD_PLL should always be connected to VCCINT through decoupling capacitor and ferrite bead.
(2) This parameter is limited in the Quartus II software by the I/O maximum frequency. The maximum I/O frequency is different for each I/O standard.
(3) The VCO frequency reported by the Quartus II software in the PLL summary section of the compilation report takes into consideration the VCO post-scale
counter K value. Therefore, if the counter K has a value of 2, the frequency reported can be lower than the fVCO specification.
(4) A high input jitter directly affects the PLL output jitter. To have low PLL output clock jitter, you must provide a clean clock source, which is less than 200 ps.
(5) Peak-to-peak jitter with a probability level of 10–12 (14 sigma, 99.99999999974404% confidence level). The output jitter specification applies to the intrinsic
jitter of the PLL, when an input jitter of 30 ps is applied.

and 1.5-V LVCMOS, the JTAG port clock to output time is 16 ns.
Periphery Performance
This section describes periphery performance, including high-speed I/O, external
memory interface, and IOE programmable delay.
I/O performance supports several system interfacing, for example, the high-speed
I/O interface, external memory interface, and the PCI/PCI-X bus interface. I/O using
the SSTL-18 Class I termination standard can achieve up to the stated DDR2 SDRAM
interfacing speeds with typical DDR SDRAM memory interface setup. I/O using
general-purpose I/O standards such as 3.0-, 2.5-, 1.8-, or 1.5-LVTTL/LVCMOS are
capable of a typical 200 MHz interfacing frequency with a 10 pF load.

Actual achievable frequency depends on design- and system-specific factors. Perform
HSPICE/IBIS simulations based on your specific design and system setup to
determine the maximum achievable frequency in your system.

I/O Timing
You can use the following methods to determine the I/O timing:
■
the Excel-based I/O Timing.
■
the Quartus II timing analyzer.
The Excel-based I/O Timing provides pin timing performance for each device density
and speed grade. The data is typically used prior to designing the FPGA to get a
timing budget estimation as part of the link timing analysis. The Quartus II timing
analyzer provides a more accurate and precise I/O timing data based on the specifics
of the design after place-and-route is complete.

The JEDEC standard for SSTl and HSTL I/O standards defines both the AC and DC input signal
values. The AC values indicate the voltage levels at which the receiver must meet its timing
specifications. The DC values indicate the voltage levels at which the final logic state of the
receiver is unambiguously defined. After the receiver input crosses the AC value, the receiver
changes to the new logic state. The new logic state is then maintained as long as the input stays
beyond the DC threshold. This approach is intended to provide predictable receiver timing in the
presence of input waveform ringing.
