Notes to Table 5–2:
(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 Using
MAX II Devices in Multi-Voltage Systems chapter in the MAX II Device Handbook.

(4) All pins, including clock, I/O, and JTAG pins, may be driven before VCCINT and VCCIO are powered.
(5) MAX IIZ devices are only available in the commercial temperature range.
(6) 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.
