Altera has identified an issue with Cyclone III MSEL pins connected to V
high. If V
the MSEL pins may be sensed at a different setting than was intended. The device
might then require a power cycle to recover. This issue does not occur when the
device is in user mode or when configuration has started.
Connect MSEL pins to V
point then the POR circuit will reset the device. If you have already connected the
MSEL pins to V
recommended operating condition voltage level and stays within the voltage min and
max. A monotonic rise will prevent the issue from occurring.
Cyclone III EP3C25 ES Revision B and C and EP3C120 ES Revision A devices might
exhibit a momentary current surge from the V
system’s V
transition into user mode as intended. This issue will be fixed in all production
devices. While the size of the current surge is dependent on your design and on
Quartus II placement and routing, the following currents are maximums for each
device.
