Table 1–19 lists the weak pull-up resistor values for Arria II GZ devices.
Hot Socketing
Table 1–20 lists the hot-socketing specification for Arria II GX and GZ devices.
Schmitt Trigger Input
The Arria II GX device supports Schmitt trigger input on the TDI, TMS, TCK, nSTATUS,
nCONFIG
, nCE, CONF_DONE, and DCLK pins. A Schmitt trigger feature introduces
hysteresis to the input signal for improved noise immunity, especially for signals with
slow edge rates.
Table 1–21 lists the hysteresis specifications across the supported VCCIO range for
Schmitt trigger inputs in Arria II GX devices.

Notes to Table 1–19:
(1) All I/O pins have an option to enable weak pull-up except configuration, test, and JTAG pins.
(2) 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
(3) Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO.

Note to Table 1–20:
(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 I/O pin
capacitance and “dv/dt” is slew rate.
