Notes:
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.
