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
(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
(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
(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
