19 / 82 page Chapter 1: DC and Switching Characteristics for Stratix IV Devices 1–11 Electrical Characteristics March 2014 Altera Corporation Stratix IV Device Handbook Volume 4: Device Datasheet and Addendum Hot Socketing Table 1–15 lists the hot socketing specifications for Stratix IV devices. Internal Weak Pull-Up Resistor Table 1–16 lists the weak pull-up resistor values for Stratix IV devices. COUTFB Input capacitance on the dual-purpose clock output and feedback pins 5 pF CCLK1, CCLK3, CCLK8, and CCLK10 Input capacitance for dedicated clock input pins 2 pF Table 1–14. Pin Capacitance for Stratix IV Devices (Part 2 of 2) Symbol Description Value Unit Table 1–15. Hot Socketing Specifications for Stratix IV Devices Symbol Description Maximum IIOPIN (DC) DC current per I/O pin 300 A IIOPIN (AC) AC current per I/O pin 8 mA (1) I XCVR-TX (DC) DC current per transceiver TX pin 100 mA I XCVR-RX (DC) DC current per transceiver RX pin 50 mA Note to Table 1–15: (1) The I/O ramp rate is 10 ns or more. For ramp rates faster than 10 ns, |IIOPIN| = C dv/dt, in which C is the I/O pin capacitance and dv/dt is the slew rate. Table 1–16. Internal Weak Pull-Up Resistor for Stratix IV Devices (1), (3) Symbol Description Conditions (V) Value (4) Unit RPU Value of the I/O pin pull-up resistor before and during configuration, as well as user mode if the programmable pull-up resistor option is enabled. VCCIO = 3.0 ±5% (2) 25 k VCCIO = 2.5 ±5% (2) 25 k VCCIO = 1.8 ±5% (2) 25 k VCCIO = 1.5 ±5% (2) 25 k VCCIO = 1.2 ±5% (2) 25 k Notes to Table 1–16: (1) All I/O pins have an option to enable weak pull-up except configuration, test, and JTAG pins. (2) Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO. (3) The internal weak pull-down feature is only available for the JTAG TCK pin. The typical value for this internal weak pull-down resistor is approximately 25 k (4) These specifications are valid with ±10% tolerances to cover changes over PVT. |
