Notes to tables:
(1)
Microparameters are timing delays contributed by individual architectural elements. These parameters cannot be
measured explicitly.
(2)
Operating conditions: VCCIO = 5.0 V ± 5% for commercial use in FLEX 10K devices.
VCCIO = 5.0 V ± 10% for industrial use in FLEX 10K devices.
VCCIO = 3.3 V ± 10% for commercial or industrial use in FLEX 10KA devices.
(3)
Operating conditions: VCCIO = 3.3 V ± 10% for commercial or industrial use in FLEX 10K devices.
VCCIO = 2.5 V ± 0.2 V for commercial or industrial use in FLEX 10KA devices.
(4)
Operating conditions: VCCIO = 2.5 V, 3.3 V, or 5.0 V.
(5)
Because the RAM in the EAB is self-timed, this parameter can be ignored when the WE signal is registered.
(6)
EAB macroparameters are internal parameters that can simplify predicting the behavior of an EAB at its boundary;
these parameters are calculated by summing selected microparameters.
(7)
These parameters are worst-case values for typical applications. Post-compilation timing simulation and timing
analysis are required to determine actual worst-case performance.
(8)
External reference timing parameters are factory-tested, worst-case values specified by Altera. A representative
subset of signal paths is tested to approximate typical device applications.
(9)
Contact Altera Applications for test circuit specifications and test conditions.
(10) These timing parameters are sample-tested only.
Figures 29 and 30 show the asynchronous and synchronous timing
waveforms, respectively, for the EAB macroparameters in Table 34.
