AC and DC Specifications
Hot Socketing Feature Implementation in MAX II Devices
MAX II Device Handbook
1
A device that does not support hot-socketing may interrupt system operation or cause
contention by driving out before or during power-up. In a hot socketing situation, the
MAX II device’s output buffers are turned off during system power-up. MAX II
devices do not drive out until the device attains proper operating conditions and is
fully configured. Refer to
about turn-on voltages.
MAX II devices do not have a current path from I/O pins or GCLK[3..0] pins to the
V
(or removed from) a system board that was powered up without damaging or
interfering with system-board operation. When hot socketing, MAX II devices may
have a minimal effect on the signal integrity of the backplane.
You can power up or power down the V
hot socketing, the I/O pin capacitance is less than 8 pF. MAX II devices meet the
following hot socketing specifications:

MAX II devices are immune to latch-up when hot socketing. If the TCK JTAG input
pin is driven high during hot socketing, the current on that pin might exceed the
specifications above.
I
when the device is being powered up or powered down. This specification takes into
account the pin capacitance but not board trace and external loading capacitance.
Additional capacitance for trace, connector, and loading must be taken into
consideration separately. The peak current duration due to power-up transients is
10 ns or less.
The DC specification applies when all V
powered-up or powered-down conditions.
The hot socketing feature turns off (tri-states) the output buffer during the power-up
event (either V
generates an internal HOTSCKT signal when either V
threshold voltage during power-up or power-down. The HOTSCKT signal cuts off the
output buffer to make sure that no DC current (except for weak pull-up leaking) leaks
through the pin. When V
relatively low even after the power-on reset (POR) signal is released and device
configuration is complete.
