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.
