the power supply can provide current to the device’s V
planes. This condition can lead to latch-up and cause a low-impedance
path from V
a large amount of current, possibly causing electrical damage.
Altera has ensured by design of the I/O buffers and hot-socketing
circuitry, that Cyclone II devices are immune to latch-up during hot
socketing.
The hot-socketing feature turns off the output buffer during power up
(either V
generates an internal HOTSCKT signal when either V
below the threshold voltage. Designs cannot use the HOTSCKT signal for
other purposes. The HOTSCKT signal cuts off the output buffer to ensure
that no DC current (except for weak pull-up leakage current) leaks
through the pin. When V
even after the internal POR signal (not available to the FPGA fabric used
by customer designs) is released and the configuration is finished. The
CONF_DONE, nCEO, and nSTATUS pins fail to respond, as the output
buffer cannot drive out because the hot-socketing circuitry keeps the I/O
pins tristated at this low V

ensure that they are able to operate during configuration. These pins are
expected to drive out during power-up and power-down sequences.
