This chapter describes the electric characteristics, switching characteristics, and I/O timing for Cyclone

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.

III devices. A glossary is also included for your reference.

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. Tabl e 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 Ta ble 1 –2 and undershoot to –2.0 V for a magnitude of currents less than 100 mA and for periods shorter than 20 ns. Tab le 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.

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 Tab le 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.

Electrical Characteristics

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. Tab le 1 –4 lists I/O pin leakage current for Cyclone III devices.
