2 / 42 page 1–2 Chapter 1: Cyclone IV Device Datasheet Operating Conditions Cyclone IV Device Handbook, May 2013 Altera Corporation Volume 3 1 Cyclone IV E industrial devices I7 are offered with extended operating temperature range. Absolute Maximum Ratings Absolute maximum ratings define the maximum operating conditions for Cyclone IV 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 IV devices. c Conditions beyond those listed in Table 1–1 cause permanent damage to the device. Additionally, device operation at the absolute maximum ratings for extended periods of time have adverse effects on the device. Maximum Allowed Overshoot or Undershoot Voltage During transitions, input signals may overshoot to the voltage shown 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 a percentage of high-time over the lifetime of the device. Table 1–1. Absolute Maximum Ratings for Cyclone IV Devices (1) Symbol Parameter Min Max Unit VCCINT Core voltage, PCI Express (PCIe) hard IP block, and transceiver physical coding sublayer (PCS) power supply –0.5 1.8 V VCCA Phase -locked loop (PLL) analog power supply –0.5 3.75 V VCCD_PLL PLL digital power supply –0.5 4.5 V VCCIO I/O banks power supply –0.5 3.75 V VCC_CLKIN Differential clock input pins power supply –0.5 4.5 V VCCH_GXB Transceiver output buffer power supply –0.5 3.75 V VCCA_GXB Transceiver physical medium attachment (PMA) and auxiliary power supply –0.5 3.75 V VCCL_GXB Transceiver PMA and auxiliary power supply –0.5 1.8 V VI DC input voltage –0.5 4.2 V IOUT DC output current, per pin –25 40 mA TSTG Storage temperature –65 150 °C TJ Operating junction temperature –40 125 °C Note to Table 1–1: (1) Supply voltage specifications apply to voltage readings taken at the device pins with respect to ground, not at the power supply. |
