Notes to
(1) MAX II device in-system programming and/or user flash memory (UFM) programming via JTAG or logic array is not guaranteed outside the
recommended operating conditions (for example, if brown-out occurs in the system during a potential write/program sequence to the UFM,
users are recommended to read back UFM contents and verify against the intended write data).
(2) Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V for input currents less than 100 mA and periods shorter
than 20 ns.
(3) During transitions, the inputs may overshoot to the voltages shown in the following table based upon input duty cycle. The DC case is equivalent
to 100% duty cycle. For more information about 5.0-V tolerance, refer to the
chapter in the
MAX II Device Handbook.

(4) All pins, including clock, I/O, and JTAG pins, may be driven before V

(5) For the extended temperature range of 100 to 125º C, MAX II UFM programming (erase/write) is only supported via the JTAG interface. UFM
programming via the logic array interface is not guaranteed in this range.
