Part (a) of AC Test Loads and Waveforms is used for all parameters except t
ER
and t
EA(+)
. Part (b) of AC Test Loads and Waveforms is used for t
ER
. Part (c) of AC Test
Loads and Waveforms is used for t
.
Min. times are tested initially and after any design or process changes that may affect these parameters.
The test load of part (a) of AC Test Loads and Waveforms is used for measuring t
. The test load of part (c) of AC Test Loads and Waveforms is used for measuring
t
only. Please see part (e) of AC Test Loads and Waveforms for enable and disable test waveforms and measurement reference levels.
10. This parameter is measured as the time after output disable input that the previous output data state remains stable on the output. This delay is measured to
the point at which a previous HIGH level has fallen to 0.5 volts below V
min. or a previous LOW level has risen to 0.5 volts above V
OL
max. Please see part (e) of AC
Test Loads and Waveforms for enable and disable test waveforms and measurement reference levels.
11. This specification indicates the guaranteed maximum frequency at which a state machine configuration with external feedback can operate.
12. This specification indicates the guaranteed maximum frequency at which the device can operate in data path mode.
13. This specification indicates the guaranteed maximum frequency at which a state machine configuration with internal only feedback can operate.
14. This parameter is calculated from the clock period at f
internal (1/f
) as measured (see Note above) minus t
.
15. The registers in the PALCE22V10 have been designed with the capability to reset during system power-up. Following power-up, all registers will be reset to a
logic LOW state. The output state will depend on the polarity of the output buffer. This feature is useful in establishing state machine initialization. To insure
proper operation, the rise in V
CC
must be monotonic and the timing constraints depicted in Power-Up Reset Waveform must be satisfied
