5 / 34 page Chapter 1: Cyclone III Device Data Sheet 1–5 Electrical Characteristics © January 2010 Altera Corporation Cyclone III Device Handbook, Volume 2 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. T J Operating junction temperature For commercial use 0 — 85 °C For industrial use –40 — 100 °C For extended temperature (5) –40 — 125 °C For automotive use –40 — 125 °C t RAM P Power supply ramp time Standard power-on reset (POR) (6) 50 µs — 50 ms — Fast POR (7) 50 µs — 3 ms — I Diode Magnitude of DC current across PCI-clamp diode when enabled —— — 10 mA 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) The I7 devices support extended operating junction temperature up to 125°C (usual range is –40°C to 100°C). When using I7 devices at the extended junction temperature ranging from –40°C to 125°C, select C8 as the target device when designing in the Quartus® II software. The I7 devices meet all C8 timing specifications when I7 devices operate beyond 100°C and up to 125°C. (6) POR time for Standard POR ranges between 50–200 ms. Each individual power supply should reach the recommended operating range within 50 ms. (7) POR time for Fast POR ranges between 3–9 ms. Each individual power supply should reach the recommended operating range within 3 ms. Table 1–3.
