CoolRunner-II CPLD Family
software. The AIM minimizes both propagation delay and
power as it makes attachments to the various FBs.
I/O Block
I/O blocks are primarily transceivers. However, each I/O is
either automatically compliant with standard voltage ranges
or can be programmed to become so. See
detailed information on CoolRunner-II I/Os.
In addition to voltage levels, each input can selectively
arrive through Schmitt-trigger inputs. This adds a small time
delay, but substantially reduces noise on that input pin.
Approximately 500 mV of hysteresis is added when
Schmitt-trigger inputs are selected. All LVCMOS inputs can
have hysteresis input. Hysteresis also allows easy genera-
tion of external clock circuits. The Schmitt-trigger path is
best seen in
patibility with I/O standards.
Outputs can be directly driven, 3-stated or open-drain con-
figured. A choice of slow or fast slew rate output signal is
