Electrical Characteristics
Hot Socketing
Table 2–12 lists the hot socketing specifications for Arria V devices.

Symbol
IIOPIN (DC)
IIOPIN (AC)
Description
DC current per I/O pin
Maximum
300 A
(1)
AC current per I/O pin
8 mA
DC current per transceiver transmitter (TX)
pin
IXCVR-TX (DC)
100 mA
50 mA
IXCVR-RX (DC)
DC current per transceiver receiver (RX) pin
Note to Table 2–12:
(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.
Internal Weak Pull-Up Resistor

Notes to Table 2–13:
(1) All I/O pins have an option to enable weak pull-up except the configuration, test, and JTAG pins.
(2) The internal weak pull-down feature is only available for the JTAG TCKpin. The typical value for this internal weak pull-down resistor is
approximately 25 k
(3) Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
.
(4) Valid with 10% tolerances to cover changes over PVT.
