Notes to Table 5–12:
(1) Table 5–12 values apply to commercial and industrial range devices. For extended temperature range devices, the t_CONFIG maximum values are
as follows:
Device

300 µs
EPM570
400 µs
EPM1270
400 µs
EPM2210
500 µs
(2) For more information about POR trigger voltage, refer to the Hot Socketing and Power-On Reset in MAX II Devices chapter in the MAX II Device
Handbook.
Power Consumption
Designers can use the Altera^® PowerPlay Early Power Estimator and PowerPlay
Power Analyzer to estimate the device power.
f For more information about these power analysis tools, refer to the Understanding and
Evaluating Power in MAX II Devices chapter in the MAX II Device Handbook and the
PowerPlay Power Analysis chapter in volume 3 of the Quartus II Handbook.
Timing Model and Specifications
MAX II devices timing can be analyzed with the Altera Quartus^® II software, a variety
of popular industry-standard EDA simulators and timing analyzers, or with the
timing model shown in Figure 5–2.
MAX II devices have predictable internal delays that enable the designer to determine
the worst-case timing of any design. The software provides timing simulation, point-
to-point delay prediction, and detailed timing analysis for device-wide performance
evaluation.
